Abstract

The invention relates to a method for providing transmission control protocol (TCP), a system and a relevant device thereof; wherein, the method comprises: an SSL VPN client agent receives TCP request through a first TCP connection, HTTPS message of the TCP service information containing the first TCP connection information and request by the sole SSL VPN conversation connection between the SSL VPN client agent and the SSL VPN gateway; the SSL VPN gateway memorizes the list item of the TCP service information containing the first TCP connection information and request in a TCP service information table for the SSL conversation, and after establishing a second TCP connection with the TCP server providing the requested TCP service, the message relay between the SSL VPN client agent and the TCP server is carried out according to the TCP service information table.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method and system for providing transmission control protocol (TCP) services, a secure socket layer virtual private network (SSL VPN) client agent and an SSL VPN gateway. Background technique [0002] The Secure Sockets Layer (SSL, Secure Sockets Layer) protocol is a protocol that provides secure communication services for both communication parties. It establishes a transport layer security channel between the communication parties. The main functions include encryption and authentication. The security channel it provides is Transparent, almost everything based on Transmission Control Protocol (TCP, Transfer Control Protocol) can run on top of SSL. SSL has become the de facto standard for secure communication between users and the Internet, and supporting SSL has also become a built-in function of browsers. [0003] Secure Hypertext Transfer Protocol (HTTPS, Secure Hypertext...
