Description

Data transmission method and device and electronic equipment

Technical Field

The present disclosure relates to the field of network communication technologies, and in particular, to a data transmission method, a data transmission apparatus, an electronic device, and a computer-readable medium.

Background

With the development of data communication technology, most terminal devices can support access to a network for data transmission in a data traffic and local area network manner. For example, a user may open a local area network connection at a mobile phone terminal, so as to access a web page through the local area network, or close the local area network connection, open a data traffic, and access the web page through the data traffic.

In the prior art, a user can only select one mode of a local area network or data traffic to access data at a time. In order to meet the requirement of the user on the transmission rate, it is usually preferred to transmit data by way of a local area network. However, the stability of the local area network is weak, and data access failure is easily caused in the case of weak network. When the local area network fails to access the data, the user needs to be reminded to switch the network connection, and the data can be accessed through the data flow only after the network connection is switched to the data flow, so that the data transmission rate is greatly influenced, and the data transmission rate is low.

As another aspect, the present application also provides a computer-readable medium, which may be contained in the electronic device described in the above embodiments; or may exist separately without being assembled into the electronic device. The computer readable medium carries one or more programs which, when executed by an electronic device, cause the electronic device to implement the method as described in the embodiments below. For example, the electronic device may implement the steps shown in fig. 3 to 9, and the like.

The technical solution of the embodiment of the present disclosure is explained in detail below:

Wi-Fi is currently the most widely used local area network technology, and has a small coverage area and a high transmission rate, while mobile traffic has a larger coverage area than Wi-Fi. However, the same device cannot access the server to obtain data through the Wi-Fi transmission channel and the mobile traffic transmission channel at the same time, and only the user can manually switch from the Wi-Fi transmission channel to the mobile traffic transmission channel or from the mobile traffic transmission channel to the Wi-Fi transmission channel, which results in that the data transmission rate between the devices cannot be further optimized.

The inventor tries to keep the Wi-Fi transmission channel and the traffic transmission channel on the terminal equipment at the same time, and accesses the server to acquire data through the two channels, so that the data transmission rate can be guaranteed to be maintained at a high level. However, the data transmission through the two transmission channels causes data redundancy, thereby causing high power consumption, causing serious heating of the device, and even possibly causing a problem that a service error is unavailable due to redundant data.

In view of one or more of the above problems, the present example embodiment provides a data transmission method. The data transmission method may be applied to the server 105, and may also be applied to a proxy server corresponding to the server 105, which is not particularly limited in this exemplary embodiment. Referring to fig. 3, the data transmission method may include the following steps S310 to S340:

step S310, a request data packet sent by a service request party is received.

Step S320, if the request data packet is a non-redundant data packet, forwarding the request data packet to a service party.

And S330, receiving a response data packet of the service server to the request data packet.

Step S340, determining the transmission indexes of each transmission channel between the service request party and the service request party, and determining a target transmission channel according to the transmission indexes of each transmission channel.

And S350, sending a response data packet to the service request party through the target transmission channel.

In the data transmission method provided in this exemplary embodiment, on one hand, sending response data packets to the service requester through the multiple target transmission channels between the service requester and the response data packets can ensure that the data packets are reachable, thereby avoiding the problem of data packet loss, and improving the reliability of data transmission. On the other hand, if the plurality of transmission channels all receive the request data packet sent by the service request party, only the non-redundant data packet is forwarded to the service party, so that the data forwarding times can be reduced, and the excessive occupation of resources is avoided, thereby reducing the power consumption of the equipment, reducing the problem of equipment heating, and prolonging the service life of the equipment. On the other hand, when a response data packet is sent to the service request party each time, a transmission channel with faster transmission can be selected according to the transmission indexes of the transmission channels, so that the data transmission rate can be greatly improved.

The above steps of the present exemplary embodiment will be described in more detail below.

In step S310, a request packet sent by a service requester is received.

The service requesting party and the service serving party can interact with each other, so that a service function is realized, and a service application program is improved for a user. The application program can be installed in a terminal device or a server, the application program requesting data can be used as a service requester, the application program providing data can be used as a service server, and data transmission can be performed between the application programs at the two ends through a network. For example, the service requester may be an application installed in the terminal device, and the service server may be an application installed in the server; or, the service requesting party may also be an application program in the server, and the service serving party is an application program in the terminal device; in addition, the service requester and the service server may also be applications in two terminal devices, or applications in two servers; this embodiment is not particularly limited to this.

The request packet may include identification information of the service requester itself. The identification information may include a network address of a device where the service requester is located, such as an IP address and a mac address, or may also include a network socket (socket), or other information, such as a custom identifier of the service requester, which is not limited in this embodiment. The request packet may also include identification information of the corresponding service provider, such as an IP address of the service provider, or identification information of the request packet itself, such as a packet sequence number. Of course, the request packet may further include information of data to be acquired, for example, a storage address of the data, a data type, and the like, which is not particularly limited in this embodiment.

In this exemplary embodiment, when the service requester needs to obtain data, the service requester may send a request data packet to the service server, and the device or the server to which the service server belongs may receive the request data packet, or may be a proxy server corresponding to the service server. The proxy server refers to an intermediate program that can be used to forward the request of the service requester to the service server actually corresponding to the service requester. Data transmission and reception between the service requester and the service server need to be performed through a transmission channel formed by network connection.

A transmission channel refers to a network connection between a service requester and a service server. The transmission channel may be formed by a socket of the service requester and a socket of the corresponding service server, that is, the transmission channel may include a pair of sockets. In this embodiment, the transmission channel may include multiple types, the network channel established by the Wi-Fi signal may be a Wi-Fi channel, and the network channel established by the operator base station may be a Long Term Evolution (LTE) channel. Alternatively, the network connection may be established in other manners, for example, establishing a hot spot channel through a hot spot, which is not limited in this embodiment.

When the transmission channel is established, the authority acquisition request can be sent to the service requester, so that the network connection authority of the service requester is acquired. The authority acquiring request can comprise the authorities of all transmission channels, so that the transmission channels are respectively established with the service requesting party in various ways after the authorities are acquired; permission for a particular one or more transmission channels may also be included, for example, permission for Wi-Fi connections and LTE connections, such that after obtaining the permission, a particular transmission channel is established.

Take a proxy server of a business service side as an example. The proxy server may provide a plurality of ports to establish a transmission channel with the service requester, and perform data transmission through the transmission channel, thereby receiving the request packet. Specifically, the service requester may send a connection request to the service provider according to the IP address of the service provider, where the connection request may include a socket (socket), and the socket is a combination of an IP address and a port number. And when the proxy server receives the request, the proxy server can verify the identity of the service requester, and after the verification is passed, the socket can be bound with the socket of the service requester to determine a transmission channel with the service requester, so that the request data packet of the service requester is received through the transmission channel. For example, the proxy server may receive the request packet through a Wi-Fi channel, or may receive the request packet through a data traffic channel.

In step S320, if the request packet is a non-redundant packet, the request packet is forwarded to the service provider.

Here, a non-redundant packet refers to a packet that is not duplicated with other packets. After the proxy server of the service provider receives the request packet, if the request packet is not duplicated with any packet, the request packet is a non-redundant packet, and the non-redundant packet needs to be forwarded to the service provider. If the request data packet is repeated with other data packets, the request data packet is a redundant data packet, and the redundant data packet does not need to be forwarded to a service side, so that the redundant data packet can be deleted, and the redundant data packet can also be identified, so that the identified redundant data packet is skipped when data is forwarded. By comparing the request data packet with each received data packet one by one, whether the request data packet is repeated with other received data packets can be determined, if the request data packet is repeated with other data packets, the request data packet is a redundant data packet, and if the request data packet is not repeated with other data packets, the request data packet is a non-redundant data packet.

The proxy server of the service server can be used as a server in the proxy server cluster, so that all request data packets of the service request end can be forwarded to the same proxy server through a gateway of the proxy server cluster, so that the data packets are uniformly converged to the proxy server, and whether the data packets are non-redundant data packets or not is determined on the proxy server, and the redundant data packets are deleted or identified so as to not forward the identified redundant data packets when the data packets are forwarded to the service server.

In this exemplary embodiment, the identification information of the request packet may be obtained, so as to determine whether the request packet is a non-redundant packet according to the identification information. The identification information refers to information capable of uniquely identifying a data packet, and the identification information may be information carried by the data packet itself, such as addresses of a sending end and a receiving end of the requested data packet, that is, addresses of a service requester and a service server, and the identification information may further include attribute information of the data packet, such as a size and a type of the data packet, and the embodiment is not limited thereto. The identification information may be parsed from the request packet, or the identification information may be generated by the proxy server for the request packet, for example, when the request packet is received, a serial number may be generated as the identification information through a combination of numbers and letters. If the identification information of the request data packet is the same as that of other data packets, the request data packet can be determined to be a redundant data packet, and if the identification information of the request data packet is not the same as that of any data packet, the request data packet is a non-redundant data packet.

In the present exemplary embodiment, as shown with reference to fig. 4, it may be determined whether the request packet is a non-redundant packet through the following steps S410 to S440. Wherein:

in step S410, a unique identifier of a service requester is obtained according to a request packet, and the unique identifier and a packet sequence number of the request packet are used as identifier information of the request packet. The unique identifier refers to information capable of uniquely identifying a service requester who sends the request data packet. The unique identifier can be sent to the proxy server by the service requester when the service requester establishes a connection with the proxy server, so that the proxy server can identify different service requesters through the unique identifier. Determining a generation rule of the unique identifier according to actual requirements, for example, the unique identifier may include numbers, letters, symbols, or a combination thereof; a binary code string having a certain length, for example, a 128-bit binary character string, may also be included, and this embodiment is not particularly limited thereto. The packet sequence number is the value of the seq field in the packet header of the packet, and the values of the seq fields of the packets in the same connection are different, so the value of the seq field can indicate the sequence of the packets in the same connection. When receiving the request data packet, the proxy server can obtain the data of the packet head of the request data packet, so as to extract the unique identifier and the packet sequence number, and the unique identifier and the packet sequence are used as the identifier information of the request data packet.

In step S420, each packet other than the request packet that has been received is acquired. The proxy server can receive a plurality of data packets from the service requester, and store and process the received data packets, so that all the stored data packets can be acquired. Alternatively, the proxy server may record the received data packet, generate a record information, for example, record the identification information, socket information, and the like of each data packet, thereby obtaining the record information, and determine each data packet through the record information, or obtain the data packet in other manners, for example, obtain the received data packet recorded by the service provider.

In step S430, in each data packet, if there is a data packet having the same identification information as the request data packet, it is determined that the request data packet is a redundant data packet. The request data packet is a data packet which needs to be processed currently, and each data packet can be a data packet which is processed before the request data packet, so that each data packet except the current request data packet has identification information, and if the data packets with the same identification information exist, the existence of repeated data packets can be determined. After the identification information of the request data packet is determined, whether the identification information contained in each data packet is the same as the identification information of the request data packet or not can be judged, that is, whether the unique identification and the packet sequence number of each data table are the same as the identification information of the request data packet or not is judged, and if the unique identification and the packet sequence number are the same as the identification information of the request data packet, the request data packet can be determined to be a redundant data packet.

In step S440, if there is no data packet having the same identification information as the request data packet, the request data packet is a non-redundant data packet. If the identification information of the request data packet does not exist in all the received data packets, the request data packet can be determined to be unique and is a non-redundant data packet. In this embodiment, a plurality of transmission channels may be established between the service requester and the service server, for example, a Wi-Fi channel and a data traffic channel are established, so that, if the service requester needs to send a request packet, the request packet may be sent from the two transmission channels, and thus the proxy server may receive two identical request packets, and if the two identical request packets are both forwarded to the service server, not only the transmission channels are occupied too much, which results in low efficiency of data transmission and large power consumption. In the embodiment, only the non-redundant request data packets are forwarded by judging the request data packets, so that the transmission speed and the transmission efficiency can be effectively improved and the power consumption can be reduced under the condition of a large number of data packets.

In step S330, a response packet of the service provider to the request packet is received.

After receiving the request data packet, the service requester may parse the request data packet to obtain a data entity in the request data packet, where the data entity may include information of data requested by the service requester, such as a request type, a name, and the like, and the service server generates a response data packet according to the data entity and a source address and a destination address in the request data packet, and sends the response data packet through a transmission channel, and the proxy server may receive the response data packet.

In step S340, the transmission indexes of the transmission channels with the service requester are determined, and the target transmission channel is determined according to the transmission indexes of the transmission channels.

The proxy server and the service requester may establish a plurality of transmission channels through different communication technologies, for example, a Wi-Fi channel and a data traffic channel are established through a wireless communication technology, and then, for example, a wired transmission channel is established through a network cable, which is not particularly limited in this embodiment. The transmission index is data that measures the capability of the transmission channel to transmit data, and may specifically include a transmission rate, a time delay, a packet loss rate, and the like, and may also include other indexes, such as throughput, bandwidth, and the like, which is not particularly limited in this embodiment. The transmission index of the transmission channel can be calculated by using the data packet sent on the transmission channel. For example, when a data packet is sent to a service requester through a transmission channel, the size of data sent per second by the transmission channel may be calculated, so as to determine the transmission rate of the transmission channel; or when the transmission channel receives a data packet sent by a service request party, determining the receiving time of the data packet, and then determining the time delay of the transmission channel according to the sending time and the receiving time recorded in the data packet.

There may be several service request parties that need to interact with the service party, and different service request parties may establish transmission channels with the proxy server, respectively. In order to distinguish the transmission channels of different service requesters, so as to determine the transmission indexes of the transmission channels between the service requesters, in this embodiment, the unique identifier of the service requester and each transmission channel of the service requester may be respectively bound, so as to determine the transmission indexes of the transmission channels between the service requester and the service requester through the unique identifier. Specifically, the unique identifier may determine a unique service requester, i.e., a sender of the data packet. When the proxy server receives a request data packet from a certain data channel for the first time, a unique identifier can be determined from the request data packet, so that the data channel is bound with the unique identifier, and the data channel is determined to be a service requester for sending the request data packet. Then, when a data packet is received on the proxy server, whether a transmission channel receiving the data packet has a corresponding service request party or not can be judged through the unique identifier of the data packet, if so, the data packet is recorded, and if not, the transmission channel is bound with the unique identifier. Therefore, when the transmission index between the data packet and a service request party is calculated, the transmission channel between the data packet and the service request party can be determined through the unique identification of the service request party, and the transmission index is calculated through the data packet sent or received by the transmission channel.

Referring to fig. 5, in the present exemplary embodiment, each transmission index with the service requester may be determined through the following steps S510 and S520, where:

in step S510, transmitted data corresponding to each transmission channel between the service requesters is acquired. The transmitted data may represent information for a plurality of data packets transmitted by a transmission channel, and the transmitted data may be generated by recording data packets received from the transmission channel and data packets sent from the transmission channel. For example, a transmission channel may generate a record for each received data packet, record the receiving condition of the data packet, such as whether the receiving is successful, the size of the data packet, and the receiving time, and record the socket information, the current channel type, the packet sequence number of the data packet, the timestamp, and the receiving time of each received data packet. The time stamp of the data packet is the time when the sender sends the data packet, and the channel type is the channel receiving the data packet. Each transmission channel may maintain a transmitted data so that the transmitted data for each transmission channel may be obtained. Or, the transmitted data may be maintained on the proxy server in a unified manner, information of the data packets received and sent on each transmission channel is recorded in the transmitted data, and in order to distinguish data of each transmission channel, each data packet may be identified by an identifier of each transmission channel, or five-tuple information of each data packet is recorded. In addition, the embodiment may also obtain the transmitted data in other manners, for example, the service requester and the proxy server or the service server respectively record the transmitted data packets, so as to respectively obtain records from the service requester, the service server and the proxy server and summarize the records, thereby obtaining the transmitted data.

In step S520, a transmission index for each transmission channel is calculated based on the transmitted data. The transmission indexes can be determined according to actual conditions, the number of the transmission indexes can be one or more, and the transmission indexes of the transmission channels can be respectively calculated through the transmitted data of the transmission channels. For example, the bandwidth, throughput, etc. of the transmission channel may be determined by the number of received packets and the number of transmitted packets in the transmitted data. In this exemplary embodiment, the transmission index may be determined in a plurality of ways, specifically:

the average time delay of each transmission channel can be calculated according to the time stamp of the data packet in the transmitted data, and the average time delay is used as a transmission index. The time stamp is the time recorded when the data packet is received or the time recorded when the data packet is transmitted by the transmitter included in the data packet. If the transmitted data includes information of all transmitted data packets recorded by the service requester and information of received data packets recorded by the service server or the proxy server, for the same data packet, the transmission time delay of the data packet can be calculated by using the transmission time and the reception time of the data packet, so as to calculate the average time delay of all data packets. If the average time delay is used as a transmission index to select a target transmission channel, the data can be transmitted as fast as possible, so that the data transmission speed is improved.

The packet loss rate of each transmission channel can be calculated according to the number of data packets in the transmitted data, and the packet loss rate is used as a transmission index. For each transmission channel, counting the number of all data packets sent from the transmission channel by a service requester in transmitted data, and counting the number of all data packets received from the transmission channel by a service server, so as to determine the packet loss rate of the transmission channel by using the total sending number and the total receiving number. If the target transmission channel is selected by taking the packet loss rate as the transmission index, the problem of packet loss of the data packet in the transmission process can be reduced, so that the reliability of data transmission is improved.

And calculating the time delay variance of each transmission channel according to the time stamp of the data packet in the transmitted data, and taking the time delay variance as a transmission index. For each transmission channel, the transmission delay of each data packet can be calculated, and then the delay variance of all data packets can be calculated by using the transmission delay of each data packet. The delay variance can be used for measuring the stability of the transmission channel, if the delay variance is used as a transmission index to select a target transmission channel, the stability of data transmission can be improved, and the data transmission rate can be improved under the condition of a large amount of data.

In the exemplary embodiment, for each transmission channel, a plurality of indexes are calculated according to the transmitted data of the transmission channel, and a weight is determined for each index, so that the transmission index of the transmission channel is calculated based on each index and the weight of each index. For example, three indexes of the average time delay, the time delay variance and the packet loss rate of each transmission channel can be calculated through the transmitted data of each transmission channel, and then a weight is determined for each index, so that the indexes are weighted and summed to obtain the final transmission index. The weight may be determined according to actual requirements, for example, if the requirement on the delay is higher than the packet loss rate, the weight of the average delay may be higher than the weight of the packet loss rate, and if the requirement on the stability is higher, the weight of the delay variance may be higher than the weights of other indicators. In addition, in the process of actual data transmission, the weight can be continuously adjusted, so that the requirements of different scenes are met.

In other embodiments of the present disclosure, the transmission index may also be determined in other manners, for example, a processing rate of the transmission channel is calculated by using a time when the transmission channel receives the data packet and a time when the data packet is forwarded out, the processing rate is used as the transmission index, the transmission index is calculated by a self-defined algorithm, and the like, which all belong to the protection scope of the present disclosure. If the transmission index is a single index, the transmission index can be quickly calculated by using less calculation resources. Different from a single index, the mode of calculating the transmission indexes by adopting a plurality of indexes can more accurately determine the data transmission capacity of the transmission channel although more calculation resources are needed, so that a target transmission channel with higher data transmission capacity is selected, the reliability of data transmission can be guaranteed, and the stability and the transmission rate of data transmission can be improved.

In the exemplary embodiment, after the transmission index of each transmission channel is calculated according to the actual situation, the transmission channel with the transmission index meeting the requirement can be selected as the target transmission channel. For example, the transmission channel with the minimum average delay may be selected as the target transmission channel; the transmission channel with the smallest packet loss rate may also be selected as the target transmission channel, or the transmission channel with the smallest delay variance may be selected as the target transmission channel. Referring to fig. 6, the target transmission channel may be determined through step S610 and step S620, specifically:

in step S610, among the transmission channels, a transmission channel whose transmission index meets a preset condition is determined as a target transmission channel. The preset condition may refer to a value requirement for the transmission index, and specifically may include that the transmission index is not greater than a threshold, or the transmission index is greater than a threshold, for example, the average time delay is less than 0.1, the packet loss rate is less than 0.01, and the like, which is not particularly limited in this embodiment. And selecting a target transmission channel from a plurality of transmission channels between the target transmission channel and the service requester according to a preset condition, and if a plurality of transmission channels meet the preset condition, determining all the transmission channels as the target transmission channels or selecting one transmission channel with the maximum or minimum transmission index as the target transmission channel.

In step S620, if the transmission indexes of the transmission channels do not meet the preset condition, the transmission channels are determined as target transmission channels. And respectively judging the transmission indexes of each transmission channel, and if no transmission channel meets the preset condition, determining each transmission channel of the service request party as a target transmission channel. That is, if there is a transmission index meeting the preset condition, one transmission channel with the maximum or minimum transmission index may be selected, the maximum transmission effect may be obtained by sending a response data packet from the transmission channel, if there is no transmission channel meeting the preset condition with the service requester, the data packet may be transmitted from each transmission channel, and the data packet may also reach the service requester at the fastest transmission rate, thereby ensuring that the data transmission effect is currently optimized. In other embodiments of the present disclosure, a certain number of transmission channels with the service requester may be randomly selected as target transmission channels, for example, two transmission channels are selected as target transmission channels, three transmission channels are selected as target transmission channels, and the like, or a specific transmission channel is selected as a target transmission channel by default, which all belong to the protection scope of the present disclosure.

Before determining and calculating the transmission indexes of the transmission channels, whether the transmission channels are normally opened or not can be detected, and therefore the transmission channels are filtered. Exemplarily, based on the transmitted data of each transmission channel, a useless channel in each transmission channel between the service requester and the service requester can be determined; further, the useless channel is cleaned. The useless channel refers to a transmission channel which is closed, or a transmission channel which has not received or sent a data packet for a period of time. Specifically, the time of last sending or receiving data packet of the transmission channel can be determined according to the transmitted data, so as to calculate the time difference between the time and the current time, and if the difference exceeds the preset time limit, the transmission channel can be determined as a useless transmission channel; the preset time period may be 1 minute, 2 minutes, or 5 minutes, or may be other values, for example, 90 seconds or 150 seconds, and this embodiment is not particularly limited thereto; or, acquiring a state parameter of the transmission channel, and if the value of the state parameter is off, determining that the transmission channel is a useless transmission channel. In addition, the useless transmission channel may also be determined in other manners, for example, a test packet is sent to the service requester through the transmission channel, and if the sending fails, the transmission channel is determined to be the useless transmission channel, and the like. After the useless transmission channel is determined, the transmission channel can be cleaned, and the data packet or other data stored in the transmission channel can be cleaned, so that the IP address and the port number bound by the transmission channel can be used by other service requesters, resources are prevented from being occupied inefficiently, and the use efficiency of the channel is improved.

In step S350, a response packet is sent to the service requester through the target transmission channel.

The target transmission channel is a transmission channel with better transmission indexes in a plurality of transmission channels between the service server and the service requester, so that the response data packet is sent from the target transmission channel, and the response data packet can reach the service requester more quickly. And after the response data packet is sent, adding the record of the response data packet in the transmitted data of the target transmission channel, so as to update the transmission index of the target transmission channel by using the information of the response data packet, so that when the data packet is sent to the service requester next time, a new target transmission channel is determined according to the updated transmission index.

In this embodiment, a transmission channel may be established between the proxy server of the service provider and the service provider, and then the proxy server receives the request data packet sent by the service provider, and sends a response data packet corresponding to the request data packet back to the service provider from the target transmission channel, so that a transmission channel with better transmission performance may be selected according to the data transmission condition of the transmission channel, thereby optimizing the data transmission rate to the greatest extent and improving the availability of the service. However, it can be understood by those skilled in the art that, in the present embodiment, the data packet between the service requester and the service provider can also be transmitted by establishing a transmission channel between the proxy server of the service requester and the service provider, or establishing a transmission channel between the proxy server of the service requester and the proxy server of the service provider. Therefore, the data transmission method provided by the present exemplary embodiment may also be executed on a server or a terminal device to which the service requester belongs, or on a proxy server of the service requester. As shown in fig. 7, taking a proxy server of a service requester as an example, the data transmission method may include the following steps:

and S710, determining each transmission channel between the service provider and the service provider, and determining a target transmission channel according to the transmission index of each transmission channel.

Step S720, receiving a request data packet of a service request party.

And S730, sending the request data packet of the service request party to the service party through the target transmission channel.

And step S740, receiving a response data packet of the service party to the request data packet.

And S750, if the response data packet is a non-redundant data packet, forwarding the response data packet to the service request party.

In this embodiment, the proxy server of the service requester needs to establish a plurality of transmission channels with the proxy server of the service provider, and then may send some test data packets through each transmission channel, so as to determine the transmission index of each transmission channel through the test data packet, then determine the target transmission channel that meets the preset condition, and send out the request data packet through the target transmission channel. If the transmission channels meeting the conditions do not exist, the data packets can be respectively sent from the plurality of transmission channels, the proxy server of the service server can take the data packet which arrives fastest as the request data packet and filter the redundant data packet, so that the data packet can be ensured to be reachable, the transmission rate of the data packet can be improved, each transmission channel can be fully utilized, and the data transmission performance is greatly optimized.

Since the service server may be a server in a server cluster, and the server may have a plurality of gateways, when data transmission is performed with the service server, a gateway may be selected first through a routing service. Illustratively, a routing address corresponding to the service requester can be determined; and then the request data packet is sent to the routing address through a transmission channel between the routing address and the request data packet, so that the request data packet is forwarded to the service party through the routing address. Specifically, the proxy server of the service requester may send a connection request to connect with the service server. The connection request may be sent to a routing server connected to the service provider, and when the routing server receives the connection request, the area where the service provider is located may be determined according to the IP address of the service provider included in the connection request, so as to select a target gateway closest to the area, and return the IP address of the target gateway to the service provider. After receiving the IP address of the target gateway, the service server may send a request packet to the target gateway, and similarly, the request packet may be forwarded to the corresponding routing address by the proxy server of the service requester, so that the request packet of the service requester is forwarded to the corresponding target gateway through the routing address and is forwarded to the corresponding target server through the target gateway. The server corresponding to the gateway or the proxy server of the server may be preset in advance, so that a plurality of gateways are set to forward the data packets to the same proxy server, so that the data packets are aggregated on the proxy server, data filtering is performed on the proxy server, and redundant data packets are discarded.

Illustratively, fig. 8 shows a data interaction process between a proxy server of a service server and a proxy server of a service requester. As shown in fig. 8, the client 81 may be a service requester, such as a game client, a browser, etc., and the server 88 may be a service server, such as a game client, a web server, etc. The client 81 can establish a data connection with the

server agents

86, 87 through the routing service, thereby forming a transmission channel for data, and transmit data between the server 88 and the client 81 through the transmission channel. In the present embodiment, Wi-Fi channel and LTE channel are taken as examples. The

server agents

86 and 87 may be proxy servers of the server 88, the client agent 82 may be a proxy server of the client, and the client may use the server agent as the server, that is, the client and the server cannot perceive the existence of the other agent. Alternatively, the identification information of the proxy may be added to the data packet, so that the client or the server can specify that the data packet is forwarded by the proxy service.

Specifically, in step S801, the client transmits a packet requesting an IP address and a port number. The data packet may be received by the client agent 82. If the client needs to establish a connection with the server or the server proxy, an IP address and a port number of the server need to be applied, and the routing service 83 connected to the client can select the

server gateway

84, 85 corresponding to the client. In step S802, the client agent 82 forwards the packet requesting the IP address and port number to the routing service 83. In the routing service 83, a server gateway corresponding to the client may be selected according to an area where the IP address of the client is located and an area of the IP address of the requested server, and the server gateways corresponding to different transmission channels may be different, for example, the server gateway of the LTE channel may be 84, and the server gateway of the Wi-Fi channel may be 85. In step S804, the routing service 83 may send the packet back to the proxy server 82. The IP address and port number of the server agent 86 may be included in the loopback packet. In step S804, the client agent 82 may forward the packet back to the client 81. In step S805, the client 81 sends a message a to the server 88. The message a is sent out in a data packet and received by the client agent 82. If the target transmission channel can be determined in the Wi-Fi channel and the LTE channel, the message A is sent only through the target transmission channel, and if the target transmission channel cannot be determined, the message A is sent through the two channels. In step S806, the client agent 82 transmits the message a through the LTE channel. And, in step S807, the client agent 82 transmits the message a through the Wi-Fi channel. Different transmission channels may correspond to different gateways, and a target server proxy for gateway forwarding may be preset, so that different gateways may forward a message to the same target server proxy, for example, the target server proxy is 86, and thus, a message a sent from a Wi-Fi channel or an LTE channel may be forwarded to the same server proxy 86 by the corresponding

server gateway

84 or 85. In step S808, the server agent 86 filters the received message a and sends the non-redundant message a to the server 88; after receiving the received message a, the server agent 86 may determine whether the message a has been forwarded, determine whether the unique identifier of the transmission channel and the message a has been bound if the message a has not been forwarded, and if the unique identifier of the message a has been bound, may store information of the message a, for example, socket information, a current transmission channel type, a packet sequence number, a timestamp, and a five-tuple of receiving time corresponding to the message a, and then forward the message a according to protocol header information; and the transmission index of the current transmission channel can be updated by using the message a so as to determine the target transmission channel. In step S809, if the target channel is an LTE channel, the service agent 86 receives the packet of the message a from the service, and then sends the packet through the LTE channel. In step S810, if the target channel is a Wi-Fi channel, the server agent 86 sends the packet back of message A over the Wi-Fi channel. The server agent 86 may determine the unique identifier of the client according to the message a, and determine the corresponding socket through the unique identifier, so as to send the packet of the message a to the client through the socket. In step S811, after receiving the return packets of the message a respectively sent from the Wi-Fi channel and the LTE channel, the server agent 82 filters the return packets and forwards the non-redundant return packets to the client 81; the packet sequence number can be extracted from the packet header of the loopback packet, whether the loopback packet is the first packet or the redundant packet can be judged through the packet sequence number, if the loopback packet is the first packet, the loopback packet is forwarded to the client, if the loopback packet is the redundant packet, the loopback packet is ignored or deleted, and the transmission index of the current channel is updated by using the loopback packet so as to be convenient for selecting a target transmission channel next time.

Fig. 9 shows a data processing flow on the server agent 86 according to the present embodiment. As shown in fig. 9, in step S901, a packet of a transmission channel is received by receiving an event; e.g., by epoll thread for receipt of data packets. In step S902, the useless channel is cleared. In step S903, it is determined whether there is a reception event trigger, and if so, step S904 is executed. In step S904, a data packet in the received event is obtained and the current socket is recorded; the socket is a socket of a sender sending the data packet, that is, a socket of the client agent. In step S905, whether the data packet is complete is determined; if not, the current channel cannot normally receive the data packet, and the current channel can be identified as a useless channel so as to be convenient for cleaning the current channel; if so, step S906 is performed. In step S906, it is determined whether the data packet is sent by the client; if the client sends the message, step S908 is executed; if the transmission is not the client transmission, the transmission is the server transmission, and step S907 is executed. In step S907, the packet is forwarded to the client. In step S908, the data packet is parsed; parsing the packet may result in information contained in the packet, such as five-tuple information of the packet. In step S909, it is determined whether a transmission channel is established with the client, and if yes, step S910 is performed, and if no, step S911 is performed. In step S910, the quintuple information of the packet is saved and the transmission index is updated. In step S911, the transmission channel is updated; if no transmission channel is established between the client and the transmission channel, binding the transmission channel requested to be connected by the client and the unique identifier of the client so as to store the transmission channel, namely, storing the socket of the client and the current socket of the server agent receiving the data packet, and binding the socket of the server agent, the socket of the client and the unique identifier of the client. In step S912, it is determined whether the packet is a redundant packet according to the unique identifier and the packet sequence number; if yes, go to step S913, discard the redundant packet; if not, step S914 is performed. In step S914, the packet is added to the forwarding queue. In step S915, the data packet in the forwarding queue is forwarded to the server through the asynchronous thread. In step S916, whether the current channel is successfully transmitted is determined; if yes, the transmission is completed; if not, step S917 is performed. In step S917, the socket of the current channel is closed; when the current socket cannot send a data packet, the socket can be closed, so that the problem that the next data packet is sent from the channel again to cause failure in sending is avoided, and the current channel can contain a plurality of sockets, for example, the socket of a server agent and the socket of a client agent can be closed. In step S918, the current channel is identified as a useless channel. And then, processing the next data packet, and finishing the current data interaction between the server and the client after all the data packets are processed.

In an exemplary embodiment, a client user interface is also included, which may include a plurality of visualization components to enable interaction with a user. For example, when a user plays a game, surfs the internet, chats a video and broadcasts directly through application software on a mobile phone, the permission of an application can be opened through the user interface, so that the data transmission method is triggered, a Wi-Fi channel and an LTE channel between the application client and the server are opened, data are transmitted through the two channels, data interaction is accelerated, and the user experiences the accelerated data transmission effect. For example, as shown in fig. 10, when a user needs to accelerate an application, the user may click an authority switch 1001 corresponding to the application, so as to start dual-channel data transmission between a client of the application and a corresponding server, for example, the user may select to start an authority of the application a, the application a may establish a Wi-Fi channel and an LTE channel with the server of the application a, and when the application a sends a packet to the server or the server of the application a sends a packet to the application a, one transmission channel may be selected from the Wi-Fi channel and the LTE channel to send the packet, or both transmission channels may be sent simultaneously.

Taking application A as an example, after the two-channel acceleration is started, the transmission index of data transmission between the application A and the corresponding server can be determined, and the transmission index is displayed to the user through the user interface, so that the user can definitely feel the improvement of the transmission effect compared with the transmission effect of a single transmission channel, and the user can visually experience the acceleration effect for the application A. As shown in fig. 11, the user may click on a display page entering the application a, and the current network speed, network latency, and network stability of the application a may be displayed in the display page. In addition, other controls, such as a "stop acceleration" control 1101, may also be added to the display page, and after the user clicks the control 1101, the acceleration may be stopped, so that the state between the application a and its server is restored to a state in which data is transmitted only through a single transmission channel.
