Improved tcp proxy method based on wide area network data compression

Abstract

The invention discloses an improved TCP proxy method based on wide area network data compression. When the proxy server detects that a client in the local area network sends a connection request to a server in the target local area network, the proxy server will send the connection request with the wide area network mark to the proxy server. To the proxy client; the proxy server and the proxy client negotiate private options during the connection establishment process; after the connection is completed, the proxy client and the proxy server respond to the data in the local termination mode; based on the wide area network environment, the proxy server and the proxy The data communication between the clients adopts the improved TCP protocol mechanism and cooperates with the wide area network compression technology. The invention can effectively reduce the time overhead of wide area network data transmission, improve the utilization rate of wide area network bandwidth, and accelerate the speed of file and data transmission.

Description

technical field [0001] The invention relates to wide area network acceleration technology, in particular to an improved TCP proxy method based on wide area network data compression. Background technique [0002] With the rapid development of the economy and the rapid progress of science and technology, the form and scale of enterprises have also undergone tremendous changes. Whether it is a large enterprise group or a small and medium-sized enterprise in the process of rapid development, the distributed enterprise structure is a difficult problem that enterprises need to face in the construction of information systems and office automation. A large number of domestic and even foreign branches and offices (hereinafter collectively referred to as branches) exist. Each branch has its own business system and data. Internal small information systems and work networks are connected to work together to achieve the best shared solution for large-scale data transmission and applicat...

Problems solved by technology

[0003] Due to the delay caused by the response mechanism and congestion control of the TCP protocol itself, and the security of the TCP protocol was not considered too much at the beginning of its birth, coupled with the transmission efficiency of the wide area network, network delay and network congestion, etc. Influenced by various factors, the main problem when each branch of the enterprise uses TCP for data transmission is whether it can effectively improve the efficiency of data transmission.

It is very common for wide area networks to cross regions and cross operators. Packet loss and delay caused by a large number of routes and gateways greatly reduce the use effect of the transmission system.
