Abstract

The invention relates to a technique for recombining, replacing, compressing and encapsulating network communication messages, in particular to a wide area network VPN accelerating gateway and its accelerating communication system and method. The WAN VPN acceleration gateway is: network protocol stack, IPSec and Internet key exchange protocol module, TCP agent and tunnel module and network protocol stack call in turn to form a closed-loop system, while TCP agent and tunnel module call the application package library module one-way Functions provided; ACK proxy module, package/data label cache/compression module, IPSec and Internet key exchange protocol modules are called sequentially, while package package/data label cache/compression module calls data label cache library one-way function function. The invention reduces the transmission of repeated data, greatly improves the link data transmission rate, and greatly enhances the high speed and reliability of the network.

Description

technical field [0001] The present invention relates to a technology for recombining, replacing, compressing and encapsulating network communication messages, in particular to a wide area network VPN acceleration gateway and its accelerated communication system and method; in particular, it relates to a virtual private network device An accelerated communication system and method for high-speed, smooth and safe network communication across a complex wide area network (including traversing firewalls and special routers and other equipment) during the communication process of IP layer security protocols. Background technique [0002] With the development of the Internet (Internet or WAN), more and more enterprises, universities and government agencies have begun to use the Internet for communication applications. E-government and e-commerce have become a way of life and work for people. Data interaction has become highly dependent on the Internet. In addition, mass data transm...
