A wireless network bilateral accelerated transmission method, comprising steps of: constructing, by a client and a server, a bilateral accelerated transmission protocol, in which a transmission layer uses a user datagram protocol and an application layer constructed according to a transmission control protocol, TCP, uses a universally unique identifier of the client to uniquely identify a connection between the client and the server; and performing, by the client and the server, transmission of data comprising the universally unique identifier, wherein specific steps of constructing, by the client and the server, the bilateral accelerated transmission protocol comprise registering, by the client, with the server by sending a registration request to the server to acquire the universally unique identifier of the client from the server; and sending, by the server, the universally unique identifier of the client to the client, and configuring, by the server, an initial transmission window and transmission protocol parameters based on a network type currently used by the client comprised in the registration request, wherein the wireless network bilateral accelerated transmission method further comprises: when network switch occurs at the client, sending, by the client, new network information to the server; receiving, by the server, the new network information sent by the client, and based on the universally unique identifier of the client and the new network information, updating, by the server, a transmission window corresponding to the client and other protocol parameters at the server; and continuing to perform, by the client and the server, transmission of data comprising the universally unique identifier. constructing, by a client and a server, a bilateral accelerated transmission protocol, in which a transmission layer uses a user datagram protocol and an application layer constructed according to a transmission control protocol, TCP, uses a universally unique identifier of the client to uniquely identify a connection between the client and the server; and performing, by the client and the server, transmission of data comprising the universally unique identifier, wherein specific steps of constructing, by the client and the server, the bilateral accelerated transmission protocol comprise registering, by the client, with the server by sending a registration request to the server to acquire the universally unique identifier of the client from the server; and sending, by the server, the universally unique identifier of the client to the client, and configuring, by the server, an initial transmission window and transmission protocol parameters based on a network type currently used by the client comprised in the registration request, wherein the wireless network bilateral accelerated transmission method further comprises: when network switch occurs at the client, sending, by the client, new network information to the server; receiving, by the server, the new network information sent by the client, and based on the universally unique identifier of the client and the new network information, updating, by the server, a transmission window corresponding to the client and other protocol parameters at the server; and continuing to perform, by the client and the server, transmission of data comprising the universally unique identifier. when network switch occurs at the client, sending, by the client, new network information to the server; receiving, by the server, the new network information sent by the client, and based on the universally unique identifier of the client and the new network information, updating, by the server, a transmission window corresponding to the client and other protocol parameters at the server; and continuing to perform, by the client and the server, transmission of data comprising the universally unique identifier.
