Embodiment Construction

[0045] Such as figure 1 Shown, in one embodiment, a kind of network data compression method comprises the steps:

[0046] In step S110, the data sending end judges whether the type corresponding to the network data belongs to the preset network traffic type, and if so, proceeds to step S130, and if not, proceeds to step S150.

[0047] In this embodiment, before the transmission of network data, the judgment of the network traffic type to which the network data belongs will be firstly carried out, so as to facilitate the selection of an appropriate network data compression method according to different network traffic types, so as to improve the compression efficiency of network data , thereby greatly reducing the network bandwidth spent.

[0048] In one embodiment, the network data may include network data corresponding to static webpages, network data corresponding to dynamic webpages, and video data, etc., and the preset network traffic type will include network data corres...

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...
