Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] The schematic diagram of multiplexing based on TCP connection is as follows figure 1 shown. The channel between the proxy server and the server is multiplexed by multiple clients, and a TCP connection pool management program is installed on the proxy server side. It provides fast establishment and deletion of TCP connections, can reduce the resource and time consumption of TCP creation and release, and improve the performance of proxy servers. The followin...

Abstract

The invention discloses a multiplexing method based on transmission control protocol (TCP) connection. The method is implemented by multiplexing a channel between a proxy server and a server through a plurality of clients. A Client tries to communicate with the server, a SOCKET connecting request is required to be established between the Client and the proxy server, a TCP connection pool management program is installed in the proxy server, a unique ID is distributed to the Client after the connection request is legal, the ID and the SOCKET are used as a key value pair and stored in a forwarding table, the communication request of the Client is agreed, the distributed ID is carried back, and equivalently, a virtual channel for bidirectional communication is established between the Client and the Server. By the method, the frequency of creating and destroying the SOCKET in the server is reduced, and the resources of the server are saved. Meanwhile, multiplexing is realized by establishing the virtual channel between the server and numerous clients.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a multiplexing method based on TCP connections. Background technique [0002] With the popularization of firewalls, the government, enterprises and other departments pay more and more attention to the security of the intranet, and the measures taken are becoming more and more strict. In order to enhance the security of the intranet, firewalls often only open individual ports to the outside world, and only allow individual network connections to communicate with the intranet. In this case, if you try to connect to the server in the intranet, it will be rejected by the firewall. Therefore, it is necessary to find a method that can not only satisfy the communication with the intranet server, but also ensure the security of the intranet. [0003] The patent application for invention with the application number CN201210197788.0 discloses a method for allocating at least one ef...
