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 in the following embodiments.

Fig. 1 shows a flowchart of a communication link selection method according to an embodiment of the present application, which specifically includes the following steps:

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

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

Step S106: based on a preset weighting algorithm, carrying out weighted calculation on a plurality of network quality sub-parameters contained in each network quality parameter to obtain a communication score of each communication link, wherein the network quality sub-parameters comprise packet loss rate, delay data, fluctuation data and load data;

step S108: and determining one of the communication links as a target communication link according to the communication score of each communication link.

The communication link is used for realizing 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, and it is required to be noted that the server is required to transfer information when the client performs data interaction with other clients.

Based on this, because there is a physical distance between the client and the server, there is a certain delay in the transmission of the data packet, in order to find the lowest delay session between two points, a plurality of communication links are established, then the client sends a detection data packet to the established plurality of 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 back the detection data packet to the client through the communication link, the client monitors according to the round trip condition of the detection data packet, and can determine the network quality parameter of the communication link, and by weighting calculation is performed on the packet loss rate, delay data, fluctuation data and load data contained in the network quality parameter, the communication score of the communication link is obtained, and the communication link with the highest communication score is selected, namely the target communication link is used as the link for the communication of the client.

Specifically, in an actual usage scenario, when a client sends UDP data packets to a destination port, a plurality of links of UDP and a plurality of TCP are first created at the same time, the number of links is determined according to the number of ports, generally 3 links of one port are used, each link enables different source ports and different destination ports, a plurality of detection data packets are sent to each link, and are used for respectively detecting network quality parameters of UDP and TCP links, after obtaining the network quality parameters of each data packet, a weighting algorithm is used for determining a communication score, and a communication link with the best communication quality is selected as a link of data transmission, and in an actual measurement scenario, the above manner can always improve the communication quality by 5% -10%.

Further, based on the communication requirement of the client, a process of establishing a plurality of communication links is implemented as follows in this embodiment:

determining the port address of the client and the target address of the client communication; and determining a plurality of access nodes according to the port address and the target address, and establishing a plurality of communication links according to all the access nodes.

The method comprises the steps of determining a port address of a client according to communication requirements of the client, determining a target address of target equipment in the process of communicating the client with the target equipment, determining a corresponding access node according to the port address and the target address, and establishing a communication link according to the access node.

Specifically, if the port address of the client is U, the destination address of the target device is V, the U and V may be connected through the servers set up in each city, and in this case, if the client is in the communication responsibility range of the server a, and the access node corresponding to the server a is a, the target device is in the communication responsibility range of the server B, and the access node corresponding to the server B is B, and in addition, there is an access node C of the server C, and an access node D of the server D, then the communication links that may 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.

Further, through the process that the client sends the corresponding detection data packet to each communication link, in this embodiment, the specific implementation manner is as follows:

determining a communication protocol between the client and each communication link, and generating the detection data packet corresponding to each communication link according to the communication protocol; and sending the corresponding detection data packet to each communication link through the client.

The communication protocol availability between the client and the communication link, such as the availability of ICMP, UDP, TCP protocols, needs to be determined, and then corresponding detection data packets, such as ICMP packets, UDP packets, and TCP packets, are sent according to the communication protocol availability.

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

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

Further, based on a preset weighting algorithm, a process of weighting and calculating a plurality of network quality sub-parameters included in each network quality parameter to obtain a communication score of each communication link is implemented as follows in this embodiment:

According to a plurality of network quality sub-parameters contained in each network quality parameter, adjusting the weight coefficient of the weighting algorithm; and carrying out weighted calculation on a plurality of network quality sub-parameters in each network quality parameter according to the adjusted weight coefficient to obtain the communication score of each communication link.

Further, the delay data is processed through a preset variance algorithm, and the fluctuation data is obtained.

The process of determining the access node associated with the communication link can be understood as a process of determining the port of the server responsible for the communication of the client, after receiving the detection data packet sent by the client, the server feeds back the detection data packet to the client, determines the packet loss rate of any communication link by monitoring whether the detection data packet has packet loss, and records the delay condition of the detection data packet to obtain delay data of any communication link; performing the time delay data memory processing on any communication link through a variance formula, and calculating to obtain the fluctuation data of the communication link; load data of any communication link is determined according to the CPU utilization rate, bandwidth condition, PPS, memory utilization rate, whether the outlet is unobstructed and the like; and finally, carrying out weighted calculation according to the obtained packet loss rate, delay data, fluctuation data and load data to obtain the communication score of the communication link.

Further, in the actual usage scenario, the network quality of the communication link is changed in real time, in this case, the previously determined target communication link may change with time, and a situation that the communication requirement of the user is not satisfied may occur, in order to solve the problem, the communication link of the client transmitting data may be replaced, and in this embodiment, the specific implementation manner is as follows:

Selecting one of the plurality of communication links as the target communication link and another of the plurality of communication links as an alternative communication link according to the communication score of each communication link; and when the network quality of the target communication link does not meet the communication quality requirement of the client, taking the alternative communication link as the target communication link.

The communication score obtained through calculation is used for selecting a target communication link and an alternative communication link, and in an actual use scene, the target communication link generally emphasizes the delay problem, so that when the communication score is calculated, the communication link with the lowest delay can be selected by a mode of increasing the weight of delay data; the alternative communication link can be selected according to network quality sub-parameters on the other hand, such as fluctuation conditions of network communication, when the communication score is calculated under the conditions, the communication link with the smallest network fluctuation and the most stable is selected by adjusting the weight corresponding to the fluctuation data, and under the conditions of poor network quality, the alternative communication link is used for replacing the original target communication link, and data transmission is performed on 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 change in time, and the determination of the target communication link can be performed once every time a set period of time passes, for example, 10 seconds, and the same alternative communication link is replaced at the same time, and it should be noted that the specific value setting of the period of time is determined by the actual use scenario, which is not limited in this embodiment.

In addition, the network quality of each communication link is commonly affected by a plurality of factors, namely, a packet loss rate, a delay condition, a fluctuation condition and a load condition, and in a part of scenes, one of the factors becomes a main factor affecting the network quality, for example, in a part of scenes, the packet loss rate, the network fluctuation condition and the load condition of a target communication link are in a normal range in the communication process of a client, however, the delay condition of the network is very serious, and the communication scene with serious network delay cannot meet the actual communication requirement of a user, then the weight of delay data in the process of calculating the communication score is adjusted according to delay data of network delay in the corresponding network quality, so that the communication link with the fewest network delay problem is selected as the target communication link from a plurality of communication links.

Further, there are situations that the network quality of a plurality of communication links cannot meet the actual communication requirement of the user, and in this case, network compensation needs to be performed on the communication links, and in this implementation, the specific implementation manner is as follows:

Determining a target access node and a target exit node associated with the target communication link under the condition that the network quality of all the communication links does not meet the communication quality requirement of the client; determining a plurality of intermediate nodes associated with the target access node, and sending a compensation data packet to the plurality of intermediate nodes through the target access node; transmitting the received compensation data packet to the target egress node through each of the intermediate nodes; and reserving the compensation data packet which is received by the target exit node first, and de-duplicating the repeatedly received compensation data packet.

After the communication scores are obtained according to the weighted calculation, the network quality can be classified according to the communication scores, such as grading by optimizing, optimizing and differentiating, or grading by A, B, C, for example, if the network quality grades of all the communication links are "poor", in this case, it can be determined that the network quality of all the communication links does not meet the communication quality requirement of the client.

Based on the above, the key nodes between the client and the target device are divided into an entry node, an intermediate node and an exit node, wherein the number of the intermediate nodes is not limited, the entry node can be understood as a server node responsible for client communication, the exit node can be understood as a server node responsible for target device communication, and the intermediate node is a server node responsible for data transmission between the two servers, as described above, the a node of the server a is the entry node, the B node of the server B is the exit node, and the C node of the server C and the D node of the server D are the intermediate nodes.

In the process of sending the compensation data packet by the client, the compensation data packet passing through the entry node is sent to all intermediate nodes, after the intermediate nodes receive the compensation data packet, the compensation data packet is sent to the exit node, the exit node reserves the compensation data packet which arrives first, and then the compensation data packet which arrives later is abandoned.

Further, if the client continuously transmits the compensating data packet, and the communication speeds of the compensating data packet passing through the intermediate nodes are different, there are two intermediate nodes, where one intermediate node transmits the current compensating data packet to the egress node, and the last batch of compensating data packets transmitted by the other intermediate node just reaches the egress node, where the situation that the compensating data packet is confused may occur, in order to avoid the confusion problem, in this embodiment, the specific implementation manner is as follows:

Reading the data packet code of the compensation data packet received by the target exit node; inquiring an encoding table of the target exit node, reserving the compensation data packet when the data packet encoding does not exist in the encoding table, and writing the data packet encoding into the encoding table; and discarding the compensation data packet when the data packet code exists in the code table.

Wherein, by setting the corresponding data packet code for each compensation data packet, the data packet code is used as the unique identity code of the compensation data packet, so that the distinction of different compensation data packets can be realized. Besides selecting to distinguish the compensating data packet, the data packet coding can also ensure the information transmission safety of the compensating data packet, for example, MD5 code is used as the data packet coding of the compensating data packet to determine that the compensating data packet is not tampered in the transmission process.
