Problems solved by technology

[0004] The existing server-side attack defense function cannot recognize that this request comes from a normal user device or a user device that has established a connection, so the request of this user device may be discarded when the server faces an attack, affecting user experience

Abstract

An embodiment of the invention discloses a data transmission method, a server and user equipment. The method comprises that the server sends a first connection identifier to the user equipment after a first connection between the server and the user equipment is established, wherein the first connection identifier is used for identifying the first connection; the server receives requirement information for establishing transmission control protocol (TCP) connection, which is sent by the user equipment, wherein the TCP connection requirement information is used for requiring for establishing a second connection between the user equipment and the server, the second connection is the TCP connection, and the TCP connection requirement information carries the first connection identifier; the server establishes the second connection after receiving the TCP connection requirement information according to the first connection identifier; the server performs data transmission between the user equipment through the second connection. By means of the embodiment, mistaken killing of the TCP anti-attacking function can be prevented, and the legal user experience is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method, server and user equipment. Background technique [0002] The existing transmission control protocol (Transmission Control Protocol, TCP) connection process includes the following three-way handshake process. 1. At first, the user equipment sends a request to the server to establish a TCP connection; 2. The server receives the handshake signal from the client, such as a synchronization signal ( synchronous, SYN) request, allocate resources for this request, and put the request into the "semi-link queue". Finally, the server sends back a synchronous Acknowledgment (SYN ACK) message to the client. If a request stays in the semi-linked queue longer than expected, the request and its corresponding allocated resources are released. 3 After receiving the SYN ACK message, the client responds to the server with an Acknowledgment (ACK) message. After receivi...
