Network data compression method and system

Abstract

The invention provides a network data compression method and a network data compression system. The method includes: judging whether a type corresponding to network data belongs to a preset network traffic type or not via a data sending end, if so, adopting a network proxy cache to compress the network data so as to obtain identification information corresponding to the network data and transmitting the identification information, and otherwise, adopting network redundancy removal processing to achieve network data compression so as to obtain fingerprint information corresponding to the network data and transmitting the fingerprint information; receiving the fingerprint information and the identification information through the data receiving end, and restoring the network data before network redundancy processing according to the fingerprint information; and converging the network data corresponding to the identification information and the network data corresponding to the fingerprint information. By the method and the system, computation overhead can be reduced without decreasing redundancy removal rate of the network data.

Description

technical field [0001] The invention relates to computer network technology, in particular to a network data compression method and system. Background technique [0002] With the development of network infrastructure, more and more high-bandwidth networks provide users with high-speed network services. However, due to the surge of network users and more and more high-bandwidth applications, such as multimedia applications, the network bandwidth Resources are getting scarcer, and the cost of increasing network bandwidth is getting higher and higher. [0003] In order to avoid the unlimited increase of costs caused by network bandwidth requirements, various technologies for reducing network traffic are applied to network services. Among them, the most effective new technology for reducing network traffic is network redundancy deletion technology, network redundancy deletion The principle of the technology is to divide the transmitted data into blocks according to certain rule...

AI Technical Summary

Problems solved by technology

However, the network redundancy deletion technology to identify duplicate data blocks requires a large amount of calculation, which requires a large calculation overhead, and has a large processing overhead requirement for memory, storage space, and IO access.
