[0002] With the popularity of the Internet, the demand for network data transmission is increasing rapidly. The data transmission speed is limited by network bandwidth and other factors, and problems such as data lag and delay are prone to occur. In order to ensure the data transmission speed and quality of some specified application programs, a static path acceleration method is usually used to establish a dedicated data transmission channel. However, this method sends network requests of the application program and receives response data through the same path, which is difficult to adapt to different target servers. In the case that the target server is not compatible with the dedicated channel, the transmission quality cannot be ensured. In addition, the existing acceleration method has a high dependence on the communication quality of the dedicated channel, and the packet loss rate is uncontrollable. Therefore, an improved data transmission scheme is needed to overcome the above existing problems. SUMMARY

[0066] The following describes a data transmission method of the present application based on the above application environment. The embodiments of the present application can be applied to various scenarios, including but not limited to cloud technology, artificial intelligence, intelligent transportation, and assisted driving. Please refer to Figure 2 , Figure 2 is a flowchart of a data transmission method provided by an embodiment of the present application. The present specification provides method operation steps as embodiments or flowcharts, but more or fewer operation steps can be included based on conventional or non-creative labor. The order of steps listed in the embodiments is only one of the many execution orders, and does not represent the only execution order. In actual system or server product execution, the method order shown in the embodiments or the drawings can be executed in sequence or in parallel (for example, in a parallel processor or multi-threaded processing environment). Specifically, as shown in Figure 2 , the method can include the following steps.

[0067] S201: The terminal obtains a network request sent by a target application program, wherein the network request carries a destination IP of a to-be-accessed server.

[0068] In the embodiments of the present application, the target application program is an application program running on the terminal that has a data transmission acceleration requirement, which can include but is not limited to a specified game client, a multimedia client, or an instant messaging client, etc. The destination IP is the IP address of the to-be-accessed server. The target application program sends a network request to the to-be-accessed server to obtain corresponding network data, such as game resources or multimedia resources, etc. from the to-be-accessed server. Specifically, the terminal can run an acceleration application program, such as an accelerator, to obtain the network request of the target application program and perform data transmission acceleration processing on the network request. Specifically, the network request can be, for example, an HTTP request, which can be transmitted based on a TCP protocol or a UDP protocol, etc.

[0069] In actual application, before S201, the target application program needs to be registered with information, and correspondingly, the method can further include steps S301-S303.

[0070] S301: The terminal acquires running configuration information of the target application program, wherein the running configuration information includes program process identification information of the target application program.

[0071] S303: The terminal registers the running configuration information.

[0072] In specific embodiments, the program process identification information can include program process name or program process ID of the target application program, such as process name of a starting process. By registering the program process identification information and other running configuration information, process monitoring of the target application program is realized, so as to realize interception of corresponding network requests. Correspondingly, S201 specifically includes: the terminal responds to starting of the target application program, and intercepts network requests sent by a corresponding program process based on the program process identification information.

[0073] Specifically, the running configuration information can further include background service configuration information and operation configuration information, such as zone service information of a game application. In the case of data transmission acceleration processing by the acceleration application program, the acceleration application program acquires running configuration information of the target application program in response to an acceleration instruction for the target application program, registers the running configuration information in a corresponding acceleration module, and writes the running configuration information into shared memory. In response to starting of the target application program, the acceleration module injects a program process, acquires a network request, and obtains a destination IP.

[0074] S203: The terminal sends a link information query request carrying the destination IP to an acceleration server.

[0075] In the embodiments of the application, the terminal generates a link information query request carrying the destination IP, and sends the link information query request to the acceleration server. Specifically, the link information query request can be generated and sent by the acceleration application program, and the acceleration server can be a background server of the acceleration application program.

[0076] S205: The acceleration server determines acceleration link information corresponding to the destination IP based on a preset correspondence relationship among the destination IP, an acceleration access point, an acceleration node, and a convergence node.

[0077] In the embodiments of the present application, the acceleration link information includes node information of a target convergence node corresponding to the destination IP, at least two target acceleration access points, and at least two target acceleration nodes, the target acceleration access points correspond to the target acceleration nodes one by one. The target acceleration access point is the starting point of the acceleration link, the physical distance between the target acceleration access point and the local proxy of the terminal or the target application program is smaller than the physical distance between the target acceleration node and the local proxy of the terminal or the target application program; the target acceleration node is deployed in an area near the to-be-accessed server, and the physical distance between the target acceleration node and the to-be-accessed server is smaller than the physical distance between the target acceleration access point and the to-be-accessed server; and the target convergence node is the last hop server through which each acceleration link is sent to the to-be-accessed server.

[0078] In actual application, the acceleration server pre-sets the correspondence between the acceleration access point, the convergence node and the destination IP, and the correspondence between the convergence node and the acceleration node, for example, pre-stores the acceleration access point IP, the convergence node IP and the destination IP in association, and stores the convergence node IP and the acceleration node IP in association. Specifically, one destination IP can be associated with multiple acceleration access points and at least one convergence node, and a single convergence node is associated with multiple acceleration nodes. Specifically, the above-mentioned associated storage can be realized by a node list. Correspondingly, please refer to Figure 3 S205 can include the following steps S2051-S2055.

[0079] S2051: The acceleration server determines, based on the pre-set correspondence between the destination IP, the acceleration access point and the convergence node, multiple to-be-selected acceleration access points corresponding to the destination IP and at least one to-be-selected convergence node.

[0080] S2052: The acceleration server determines, based on the pre-set correspondence between the convergence node and the acceleration node, the to-be-selected acceleration nodes corresponding to each of the to-be-selected convergence nodes.

[0081] S2053: The acceleration server obtains link quality data of multiple to-be-selected communication links including the to-be-selected acceleration access points, the to-be-selected acceleration nodes and the to-be-selected convergence nodes.

[0082] Specifically, the acceleration server determines the acceleration access point associated with the destination IP as a candidate acceleration access point and determines at least one aggregation node associated with the destination IP as a candidate aggregation node based on the preset correspondence. Further, the acceleration server determines a plurality of acceleration nodes associated with each candidate aggregation node as candidate acceleration nodes based on the preset correspondence between the aggregation nodes and the acceleration nodes. The acceleration server determines a plurality of communication links based on the candidate acceleration access point, the candidate acceleration nodes, and the candidate aggregation nodes. The data transmission order in a single communication link is the candidate acceleration access point, the candidate acceleration nodes, and the candidate aggregation node in sequence, and the candidate aggregation node forwards data to the accessed server. Then, the acceleration server obtains link quality data of each communication link, which represents the communication quality of the communication link and can include but is not limited to delay value, packet loss rate, network operator type, and node location. It can be understood that the candidate acceleration access point and the candidate acceleration node can include intermediate nodes. Accordingly, S2053 can include the following steps S20531-S20534.

[0083] S20531: The acceleration server generates a plurality of link quality test requests corresponding to the respective candidate communication links based on the target IP.

[0084] S20532: The acceleration server sends the link quality test requests of each candidate communication link to the accessed server via the corresponding communication link through each candidate acceleration access point.

[0085] S20533: The acceleration server receives test response information sent by the accessed server in response to the link quality test requests of each candidate communication link via each communication link.

[0086] S20534: The acceleration server generates link quality data of each candidate communication link according to the test response information.

[0087] Specifically, after determining the plurality of candidate communication links, the acceleration server sends a link quality test request to the to-be-accessed server through each candidate communication link, so that the to-be-accessed server feeds back test response information via the communication link corresponding to the link quality test request, and then determines the link quality data of each candidate communication link. Specifically, the link quality test request can include test instructions for different types of link quality data. For example, the operator type and node location detection can be performed based on the curl command to obtain the network operator type and node geographic location of the candidate acceleration access point, the candidate acceleration node and the candidate aggregation node, and the delay value and packet loss rate test can be performed based on the ping command. For example, the ping IP method is adopted, a data packet is sent to the to-be-accessed server through each communication link, so that the to-be-accessed server feeds back a corresponding response data packet, the communication time of sending and feedback is calculated to calculate the delay value of the communication link, and the packet loss rate is determined according to the difference between the number of sent data packets and the number of received response data packets.

[0088] In some cases, the correspondence between the acceleration access point and the acceleration node can also be preset, and then the communication link is determined. In other cases, after the candidate acceleration access point, the candidate acceleration node and the candidate aggregation node are determined, the data transmission order and the correspondence between the acceleration node and the aggregation node can be used to arrange and combine them to obtain a plurality of candidate communication links, so as to respectively perform link quality detection. In other cases, in order to avoid too many candidate communication links causing too long quality detection delay, before S2053, the method can further include the following communication link determination steps S401-S403.

[0089] S401: The acceleration server obtains the access point location of the candidate acceleration access point and the acceleration node location of the candidate acceleration node.

[0090] S403: The acceleration server performs link matching on the candidate acceleration access point, the candidate acceleration node and the candidate aggregation node according to the access point location, the acceleration node location and the preset correspondence between the aggregation node and the acceleration node, to obtain a plurality of candidate communication links.

[0091] Specifically, the acceleration server can pre-store the access point location, the acceleration node location and the aggregation node location. For each candidate aggregation node corresponding to a destination IP, the physical distance between each candidate acceleration access point and each candidate acceleration node is determined according to the access point location and the acceleration node location, for each candidate acceleration access point, the candidate acceleration nodes are sorted based on the physical distance, and a specified number of candidate acceleration nodes with the shortest physical distance are determined as the acceleration nodes matched with the candidate acceleration access point, and then a specified number of candidate communication links of each candidate acceleration access point for the candidate aggregation node are obtained, and then the candidate communication links corresponding to each candidate aggregation node are obtained respectively.

[0092] For example, the candidate acceleration access points corresponding to the destination IP include access point 1, access point 2, access point 3 and access point 4, and one candidate aggregation node M, i.e., the target aggregation node M, the corresponding candidate acceleration nodes of which include acceleration node a, acceleration node b, acceleration node c, acceleration node d and acceleration node e, and the specified number is 2. The physical distance sorting is performed on each candidate acceleration access point and each candidate acceleration node, and it is determined that the closest to the access point 1 are the acceleration node a and the acceleration node c, the closest to the access point 2 are the acceleration node a and the acceleration node d, the closest to the access point 3 are the acceleration node b and the acceleration node c, and the closest to the access point 4 are the acceleration node d and the acceleration node e, which are represented by labels. The communication link corresponding to the candidate aggregation node M can be represented as: {1-a-M, 1-c-M, 2-a-M, 2-d-M, 3-b-M, 3-c-M, 4-d-M, 4-e-M}.

[0093] S2054: The acceleration server screens the plurality of candidate communication links according to the link quality data to obtain at least two target acceleration links, wherein the at least two target acceleration links correspond to the same candidate aggregation node.

[0094] S2055: The acceleration server generates the acceleration link information corresponding to the destination IP according to the candidate acceleration access points, the candidate acceleration nodes and the candidate aggregation nodes in the at least two target acceleration links, and determines the candidate acceleration access points, the candidate acceleration nodes and the candidate aggregation nodes in the at least two target acceleration links as the target acceleration access points, the target acceleration nodes and the target aggregation nodes corresponding to the destination IP.

[0095] Specifically, after obtaining the link quality data of each candidate communication link, the link quality statistical result is generated. For example, the delay value and the packet loss rate can be normalized respectively to obtain the delay reference value and the packet loss reference value, and the delay reference value and the packet loss reference value are weighted and summed to obtain the link quality statistical result.

[0096] In the case where there is one candidate aggregation node, the quality sorting is performed on the plurality of candidate communication links according to the link quality statistical result, and the preset number of candidate communication links with the optimal link quality, the candidate acceleration access points of which are different from each other and the candidate acceleration nodes of which are different from each other are determined as the target acceleration links.

[0097] In the case of multiple candidate aggregation nodes, the multiple candidate communication links are sorted as a whole, and the target aggregation node is determined based on the sorting result. For example, the first n candidate communication links with the best link quality are determined, and the candidate aggregation node corresponding to the most links among the n candidate communication links is determined as the target aggregation node. n can be greater than or equal to 1. Then, a preset number of candidate communication links with the best link quality are determined from the candidate communication links corresponding to the target aggregation node, which are used as target acceleration links. The acceleration access points in different target acceleration links are different from each other, and the acceleration nodes are different from each other. The preset number is greater than or equal to 2.

[0098] Based on the foregoing example, the communication links corresponding to the candidate aggregation node M can be represented as: {1-a-M, 1-c-M, 2-a-M, 2-d-M, 3-b-M, 3-c-M, 4-d-M, 4-e-M}, and the preset number is 3. The three target acceleration links with the best link quality determined based on the link quality statistical result are {1-a-M, 2-d-M, 3-c-M}. Correspondingly, please refer to Figure 5 , the target acceleration access point 1 sends the redirection request to the target aggregation node M through the target acceleration node a, the target acceleration access point 2 sends the redirection request to the target aggregation node M through the target acceleration node d, and the target acceleration access point 3 sends the redirection request to the target aggregation node M through the target acceleration node c, so that the target aggregation node M de-duplicates and recombines the request data and sends it to the to-be-accessed server.

[0099] S207: The acceleration server sends the acceleration link information corresponding to the destination IP to the terminal.

[0100] In the embodiment of the application, the acceleration server generates the corresponding acceleration link information after determining the target acceleration links, the target acceleration access points, the target acceleration nodes and the target aggregation nodes, and sends it to the terminal.

[0101] S209: The terminal redirects the network request according to the node information of the at least two target acceleration nodes and the target aggregation node, and obtains the redirection request corresponding to each target acceleration access point, wherein the redirection request carries the request data packet of the network request.

[0102] In the embodiment of the application, the terminal redirects the network request of the target application after receiving the acceleration link information, so as to perform data transmission with the to-be-accessed server through the specified acceleration link. Correspondingly, S209 can include the following steps S2091-S2094.

[0103] S2091: The terminal obtains the request data packet of the network request.

[0104] S2092: The terminal performs header encapsulation processing on the request data packet based on the node information of each target acceleration node, respectively, to obtain initial encapsulation data packets each corresponding to the target acceleration access point and carrying an acceleration node header.

[0105] S2093: The terminal performs encapsulation processing on each initial encapsulation data packet again based on the node information of the target aggregation node, respectively, to obtain target encapsulation data packets each corresponding to the initial encapsulation data packet and carrying an aggregation node header.

[0106] S2094: The terminal generates a redirection request corresponding to each target acceleration access point according to each target encapsulation data packet.

[0107] Specifically, the node information can include the node IP, node port (port), and global unique identifier (GUID) of the node, etc. The terminal obtains a raw request data packet of a network request, which can be a TCP data packet or a UDP data packet. For each target acceleration link, the request data packet is encapsulated according to the node information of the target acceleration node, and the generated acceleration node header can include the IP, port, and GUID of the target acceleration node, as well as the packet sequence number (seq) and destination IP, etc., to obtain an initial encapsulation data packet of each target acceleration link. Then, each initial encapsulation data packet is encapsulated with an upper layer aggregation node header, which includes the IP and port of the target aggregation node, etc., to obtain a target encapsulation data packet. Finally, each target encapsulation data packet is encapsulated according to the application layer protocol to obtain a redirection request corresponding to each target acceleration access point, i.e., a redirection request of each target acceleration link.

[0108] S211: The terminal sends each redirection request to the corresponding target acceleration access point, so that the target acceleration access point sends the request data packet to the to-be-accessed service server through the target acceleration link where the target acceleration access point is located.

[0109] In the embodiments of the present application, the terminal sends redirection requests to multiple target acceleration access points simultaneously, and the redirection request is used to instruct the corresponding target acceleration access point to send the request data packet to the target aggregation node through the corresponding target acceleration node, and to instruct the target aggregation node to send the received request data packet to the to-be-accessed service server.

[0110] Specifically, the target aggregation node receives the redirection requests carrying the request data packets sent by the target acceleration nodes, parses the redirection requests, performs deduplication processing and packet recombination on the request data packets carried by the redirection requests based on information such as the packet sequence number, obtains recombined data packets, and sends a redirection request corresponding to the recombined data packets to the to-be-accessed server, so that the to-be-accessed server feeds back response information carrying corresponding response data packets, and the target aggregation node feeds back the response information to the terminal through each target acceleration link. At the same time, when parsing each redirection request, the target aggregation node saves the node connection information of each target acceleration link, such as saving the connection information by using a conn structure, and the connection information includes node information of the target acceleration access point, the target acceleration node and the to-be-accessed server.

[0111] In the embodiments of the present application, the to-be-accessed server feeds back response information carrying response data packets in response to the redirection request sent by the target aggregation node, the target aggregation node parses the response information to obtain the response data packets, and for each target communication link, the target aggregation node first encapsulates the response data packets based on the node information (destination IP and destination port, etc.) of the to-be-accessed server and the node information of the target aggregation node based on the saved node connection information of the target communication link, obtains an initial encapsulated response packet carrying an aggregation node packet header, and sends it to the target acceleration node; the target acceleration node encapsulates the initial encapsulated response packet based on its node information to obtain a response data packet carrying an acceleration node packet header, and sends it to the target acceleration access point and then to the terminal, specifically, to the target application. Correspondingly, please refer to Figure 4 , the method further comprises the following steps.

[0112] S213: The terminal receives at least two response data packets sent by the to-be-accessed server in response to the redirection requests via the target aggregation node, the target acceleration nodes and the target acceleration access points respectively.

[0113] S215: The terminal respectively unpacks each response data packet based on the node information of the target acceleration node and the target aggregation node to obtain a respective unpacked data packet corresponding to each response data packet;

[0114] S217: The terminal performs data deduplication processing on each unpacked data packet to obtain a target data packet corresponding to the network request.

[0115] In actual application, after the terminal receives the response data packets sent by the to-be-accessed server and the target aggregation node via the target acceleration links, it unpacks the response data packets, removes the acceleration node packet header and the aggregation node packet header in sequence to obtain unpacked data packets, and performs deduplication and recombination on the unpacked data packets of each target acceleration link (target acceleration access point) based on information such as the packet sequence number to obtain the target data requested by the terminal.

[0116] In some cases, data reorganization can be performed by a local proxy server of the target application. Specifically, the terminal sends the de-duplicated data to the local proxy server, the local proxy server reorganizes the data based on the packet sequence number and other information to obtain the target data, and sends the target data to the terminal.

[0117] In summary, according to the target IP to be accessed, the data acceleration link is dynamically selected, the target application traffic is forwarded to the to-be-accessed server through the optimal path, and the feedback data is obtained, so as to realize adaptive dynamic allocation of data transmission, reduce transmission delay, and significantly improve the overall data transmission efficiency. Moreover, based on the multiple acceleration access points and the corresponding multiple acceleration links for data transmission, the packet loss rate is effectively reduced, and the data transmission quality is improved.

[0132] S24: The acceleration client encapsulates a layer of aggregation node packet header on the obtained udp packet, including the IP and port of the target aggregation node, etc.

[0133] S25: The acceleration client sends the encapsulated udp packet carrying the aggregation packet header to each target acceleration access point.

[0134] S26: Each target acceleration access point sends the udp packet to the target aggregation node via the target S5 acceleration node. That is, it is sent to the target aggregation node through each target acceleration link.

[0135] S27: The target aggregation node removes the duplicate udp data packet according to the seq, and forwards it to the game server.

[0136] S28: At the same time, the target aggregation node saves the information of each connection with the conn structure.
