Embodiment 1

[0036] The purpose of the present invention is to adopt the parallel TCP technology to optimize the application protocol without changing the existing application software and system kernel protocol stack.

[0037] Such as figure 1 As shown, the device located in the local area network of client 2 and establishing a session connection with client 2 is the proxy server 4; the device located in the local area network of server 1 and establishing a session connection with the server is proxy client 3. A network deployment can have multiple proxy servers 4 and proxy clients 3 . The communication between the proxy server 4 and the proxy client 3 is completed through the gateway 5, and a parallel TCP tunnel 10 is established in the wide area network. The agent can be deployed on the gateway 5, or it can be an independent device behind the gateway.

[0038] Data transmission between the proxy server 4 and the proxy client 3 can be accomplished through parallel TCP tunnels. Proxy s...

Abstract

The invention provides a parallel TCP (Transmission Control Protocol) technology based wide area network (WAN) communication acceleration method. The method comprises the following steps of: when a proxy server monitors that a client in a local area network (LAN) sends a session connection request to a server in a target LAN, establishing a session connection between the proxy server and a proxy client, i.e. a first session connection; based on a WAN environment, establishing a parallel TCP tunnel between the proxy server and the proxy client; connecting the proxy client and the server through a session connection based on session pool distribution, i.e. a second session connection; and carrying out data communication by the client in the LAN with the server in the target LAN through a communication channel formed by the first session connection, the parallel TCP tunnel and the second session connection. The invention can effectively reduce the time expense of the data transmission of the WAN and accelerate the speed of file and data transmission.

Description

technical field [0001] The technology of the invention belongs to the technical field of network transmission, and relates to a wide area network communication acceleration method based on parallel TCP technology. technical background [0002] The rapid development of Internet services has brought great convenience to people's work and life, and at the same time put forward higher requirements for network transmission speed and data processing speed. However, the current WAN communication mostly uses basic TCP application layer protocols such as HTTP, FTP, and My Network Places for file and data transmission. The client directly connects to the server, and the connection channel is unique. Due to the existence of a large number of transmission delays and packet loss in the WAN, only increasing the bandwidth cannot improve the transmission speed of traditional TCP, especially in networks with large delays or cross-operators, the data transmission speed based on TCP is very sl...
