When the data receiving end and the data sending end establish connection, the data receiving end inserts a specific identifier into a data packet for establishing connection, and judges whether to establish user datagram protocol accelerated transmission or traditional transmission control protocol accelerated transmission according to the content of the data packet responded by the data sending end.
And S103, after the connection is established, the data sending terminal acceleration module receives the data request sent by the data receiving terminal acceleration module, recodes the data packet, and carries out accelerated transmission to the data receiving terminal acceleration module according to the transmission strategy through the established connection.
When a data transmitting end transmits a data packet on a connection, a specific identifier inserted in the data packet during the establishment of the connection is used as a mark. In the data packet transmission process, firstly, the data packet is transmitted through a default transmission protocol, if network congestion is detected in the transmission process and packet loss is serious, transmission channel detection is carried out, for a data packet with transmission failure, the original transmission protocol of the data packet is firstly used for retransmission for 2-3 times, and if the transmission failure still occurs, another transmission protocol is used for transmission, so that the data packet is retransmitted as fast as possible.
Specifically, as shown in fig. 2, step S102 in fig. 1 specifically includes:

S10215, the connection packet is sent to the data sending terminal acceleration module.
After receiving the build-up packet, the data sending terminal acceleration module judges whether the build-up packet has a WIP identifier, if so, the data sending terminal acceleration module marks the connection according to the identifier, decodes the build-up packet, and then sends the build-up packet to a data sending terminal kernel; and if not, directly sending the build packet to the data sending end kernel.
S10216, the connection packet is sent to the kernel of the data sending end.
The kernel of the data sending end is not provided with a data sending end acceleration module, or the data sending end acceleration module processes the connection packet and then sends the connection packet to the kernel of the data sending end.

s601, the data receiving end application layer establishes a connection packet, and judges whether acceleration is needed or not according to the self acceleration strategy of the data receiving end application layer. If acceleration is required, go to step S602; if acceleration is not required, step S603 is performed.
S602, calling a corresponding data interface and setting an interface value.
The interface value corresponding to the accelerated data packet is preset at the data receiving end, for example, the interface value of the data packet which does not need to be accelerated is 0, and the interface value of the data packet which needs to be accelerated is 1. If the data receiving end application layer needs to accelerate, the interface value 1 is called at the moment, and then the connection packet is transmitted to the data receiving end kernel.
S603, sending the connection packet to a data receiving end kernel.
If the data receiving end application layer needs to accelerate, the connection packet is transmitted to the data receiving end kernel by calling a corresponding data interface, and if the data receiving end application layer does not need to accelerate, the connection packet is directly transmitted to the data receiving end kernel from the data receiving end application layer.

For example, the data packet is transmitted by using the transmission control protocol as a default; if the transmission fails, continuing to use the transmission control protocol for transmission for 2-3 times; if the transmission is still unsuccessful, the user datagram protocol is used to retransmit the data packet.
S10334, the data receiving end receives the data packet, and determines whether the data receiving end core is installed with the data receiving end acceleration module.
