In the present application, a communication link selection method is provided. The present application also relates to a communication link selection device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

FIG1 shows a flow chart of a communication link selection method provided according to an embodiment of the present application, which specifically includes the following steps:

Step S102: establishing multiple communication links based on the communication requirements of the client;

Step S104: sending a corresponding detection data packet to each of the communication links through the client, and determining a network quality parameter associated with each of the communication links according to a round-trip result of each of the detection data packets;

Step S106: Based on a preset weighting algorithm, a plurality of network quality sub-parameters included in each of the network quality parameters are weighted to obtain a communication score for each of the communication links, wherein the network quality sub-parameters include packet loss rate, delay data, fluctuation data, and load data;

Step S108: Determine one of the plurality of communication links as a target communication link according to the communication score of each of the communication links.

Among them, the communication link is used to realize information transmission between the client and other devices, such as data interaction between the client and other clients, or interaction between the client and the server. It should be noted that when the client interacts with other clients, the server is also required to transfer information.

Based on this, due to the physical distance between the client and the server, there will be a certain delay in the transmission of data packets. In order to find the lowest delay session between two points, multiple communication links are established. Then the client sends detection data packets to the multiple established communication links. For any communication link, the detection data packet is sent to the server through the communication link. After receiving the detection data packet, the server feeds the detection data packet back to the client through the communication link. The client monitors the round-trip situation of the detection data packet to determine the network quality parameters of the communication link. By weighted calculation of the packet loss rate, delay data, fluctuation data and load data contained in the network quality parameters, the communication score of the communication link is obtained, and the communication link with the highest communication score, that is, the target communication link, is selected as the link for the client to communicate.

Specifically, in actual usage scenarios, when the client sends a UDP data packet to the destination port, it first creates multiple UDP and TCP links at the same time. The number of links is determined by the number of ports. Generally, one port has 3 links, and each link uses a different source port and a different destination port. Multiple detection data packets are sent to each link to detect the network quality parameters of the UDP and TCP links respectively. After obtaining the network quality parameters of each data packet, the communication score is determined by a weighted algorithm, and the communication link with the best communication quality is selected as the link for data transmission. In actual measurement scenarios, the above method can often improve the communication quality by 5%~10%.

Furthermore, based on the communication requirements of the client, the process of establishing multiple communication links is specifically implemented as follows in this embodiment:

Determine the port address of the client and the target address of the client communication; determine multiple access nodes according to the port address and the target address, and establish multiple communication links according to all the access nodes.

Among them, the client's own port address can be determined through the client's communication needs, as well as the target address of the target device during the communication between the client and the target device. The corresponding access node can be determined based on the port address and the target address, and a communication link can be established based on the access node.

Specifically, if the port address of the client is U and the target address of the target device is V, U and V can be connected through servers established in each city. In actual usage scenarios, the service areas are often connected to each other. In this case, if the client is within the communication range of server A, and the access node corresponding to server A is a, the target device is within the communication range of server B, and the access node corresponding to server B is b, in addition, there is access node c of server C and access node d of server D, then the communication links that can be established at this time are U-a-b-V, U-a-c-b-V, U-a-d-b-V, U-a-c-d-b-V, and U-a-d-c-b-V.

Furthermore, the process of sending a corresponding detection data packet to each communication link by the client is specifically implemented as follows in this embodiment:

Determine the communication protocol between the client and each of the communication links, and generate the detection data packet corresponding to each of the communication links according to the communication protocol; and send the corresponding detection data packet to each of the communication links through the client.

Among them, it is necessary to determine the availability of the communication protocol between the client and the communication link, such as the availability of ICMP, UDP, and TCP protocols, and then send corresponding detection data packets, such as ICMP packets, UDP packets, and TCP packets, according to the availability of the communication protocol.

Furthermore, according to the round-trip result of each detection data packet, the process of determining the network quality parameter associated with each communication link is specifically implemented as follows in this embodiment:

After receiving the detection data packet, the access node associated with each communication link feeds the detection data packet back to the client through the associated communication link; monitors the transmission process of the detection data packet between the client and the access node through each communication link, and determines the network quality parameters associated with each communication link.

Furthermore, based on a preset weighted algorithm, a weighted calculation is performed on multiple network quality sub-parameters included in each network quality parameter to obtain a communication score for each communication link. In this embodiment, the specific implementation method is as follows:

According to the multiple network quality sub-parameters contained in each of the network quality parameters, the weight coefficient of the weighted algorithm is adjusted; according to the adjusted weight coefficient, the multiple network quality sub-parameters in each of the network quality parameters are weightedly calculated to obtain the communication score of each of the communication links.

Furthermore, the delay data is processed by a preset variance algorithm to obtain the fluctuation data.

Among them, the process of determining the access node associated with the communication link can be understood as the process of determining the port of the server responsible for the client communication. After receiving the detection data packet sent by the client, the server feeds the detection data packet back to the client, and determines the packet loss rate of any communication link by monitoring whether there is packet loss in the detection data packet, and records the delay of the detection data packet to obtain the delay data of any communication link; the delay data of any communication link is processed by the variance formula to calculate the fluctuation data of the communication link; and the load data of any communication link is determined according to information such as CPU utilization, bandwidth, PPS, memory usage, whether the export is unobstructed, etc.; finally, a weighted calculation is performed based on the obtained packet loss rate, delay data, fluctuation data and load data to obtain the communication score of the communication link.

Furthermore, in actual usage scenarios, the network quality of the communication link changes in real time. In this case, the previously determined target communication link may change over time and fail to meet the user's communication needs. In order to solve this problem, the communication link for transmitting data on the client may be replaced. In this embodiment, the specific implementation method is as follows:

According to the communication score of each of the communication links, one of the multiple communication links is selected as the target communication link, and another one of the multiple communication links is selected as an alternative communication link; when the network quality of the target communication link does not meet the communication quality requirement of the client, the alternative communication link is used as the target communication link.

Among them, the target communication link and the alternative communication link are selected through the calculated communication score. In the actual usage scenario, the target communication link generally focuses on the delay problem. Therefore, when calculating the communication score, the communication link with the lowest delay can be selected by increasing the weight of the delay data; and the alternative communication link can be selected based on the network quality sub-parameters on the other hand, such as the fluctuation of network communication. In this case, when calculating the communication score, the communication link with the smallest network fluctuation and the most stable one is selected by increasing the weight corresponding to the fluctuation data. In the case of poor network quality, the alternative communication link replaces the original target communication link to transmit data to the client.

Based on this, due to the characteristic that the network quality of the communication link changes, the target communication link and the alternative communication link need to be changed in a timely manner. A set time period, such as 10 seconds, can be used. Every time a time period passes, the target communication link is determined and the alternative communication link is replaced at the same time. It should be noted that the specific value setting of the time period is determined by the actual usage scenario and is not limited in this embodiment.

In addition, the network quality of each communication link is affected by multiple factors, namely, packet loss rate, delay, fluctuation and load. In some scenarios, one of these factors will become the main factor affecting the network quality. For example, in some scenarios, during the client's communication, the packet loss rate, network fluctuation and load of the target communication link are all within the normal range, but the network delay is very serious. This communication scenario with serious network delay cannot meet the user's actual communication needs. At this time, the weight of the delay data in the calculation process of the communication score will be adjusted according to the delay data of the network delay in the corresponding network quality, so as to select the communication link with the least network delay problem as the target communication link from multiple communication links.

Furthermore, there is a situation where the network quality of multiple communication links cannot meet the actual communication needs of users. In this case, network compensation is required for the communication links. In this implementation, the specific implementation method is as follows:

When the network quality of all the communication links does not meet the communication quality requirements of the client, determine the target access node and the target exit node associated with the target communication link; determine multiple intermediate nodes associated with the target access node, and send compensation data packets to the multiple intermediate nodes through the target access node; send the received compensation data packet to the target exit node through each of the intermediate nodes; retain the compensation data packet first received by the target exit node, and deduplicate the compensation data packets received repeatedly.

Among them, after the communication score is obtained according to the weighted calculation, the network quality can be graded according to the communication score, such as excellent, good, poor, or divided into A, B, C and other ratings. Taking the excellent, good, and poor ratings as an example, if the network quality ratings of all communication links are "poor", in this case, it can be determined that the network quality of all communication links does not meet the communication quality requirements of the client.

Based on this, the key nodes between the client and the target device are divided into entry nodes, intermediate nodes and exit nodes, among which the number of intermediate nodes is not limited. The entry node can be understood as the server node responsible for client communication, the exit node can be understood as the server node responsible for target device communication, and the intermediate node is the server node responsible for data transmission between the above two servers. As described above, node a of server A is the entry node, node b of server B is the exit node, and node c of server C and node d of server D are intermediate nodes.

In the process of the client sending compensation data packets, the compensation data packets passing through the entry node will be sent to all intermediate nodes. After receiving the compensation data packets, the intermediate nodes will send the compensation data packets to the exit node. The exit node retains the compensation data packets that arrive first, and the compensation data packets that arrive later are discarded. In this case, since the compensation data packets retained by the exit node are the first compensation data packets to arrive, the compensation data packets can be received with the lowest delay during data transmission, and packet loss can be reduced.

Furthermore, if the client continuously sends compensation data packets, and the communication speeds of the compensation data packets passing through each intermediate node are different, there are two intermediate nodes, one of which sends the current compensation data packet to the exit node, while the previous batch of compensation data packets sent by the other intermediate node has just arrived at the exit node. In this case, the compensation data packets may be confused. In order to avoid confusion, in this embodiment, the specific implementation method is as follows:

Read the data packet code of the compensation data packet received by the target exit node; query the coding table of the target exit node, and when the data packet code does not exist in the coding table, retain the compensation data packet and write the data packet code into the coding table; when the data packet code exists in the coding table, discard the compensation data packet.

Among them, by setting a corresponding data packet code for each compensation data packet, the data packet code is used as a unique identity code of the compensation data packet, so that different compensation data packets can be distinguished. In addition to selecting to distinguish compensation data packets, the data packet code can also ensure the information transmission security of the compensation data packet, such as using the MD5 code as the data packet code of the compensation data packet to ensure that the compensation data packet has not been tampered with during the transmission process.
