Web cache resource sharing system and method based on intelligent parent node

Abstract

The invention discloses a method and a system for sharing Web cached resource based on an intelligent father node, which are used for further reducing the back source bandwidth of a caching system and the access pressure on a source station. The technical scheme of the invention is as follows: the system comprises multiple WEB cache nodes, a source station server, a cached resource list pool and the intelligent father node. The multiple Web cache nodes are used for caching the resource, receiving the user request and returning back the resource corresponding to the user request to the user; the source station server is used for storing the source data; the cached resource list pool is used for receiving and reporting the resource of the multiple Web cache nodes, and forming a resource detailed list of all the Web cache nodes; and the intelligent father node is used for receiving the request of one Web cache node, inquiring the cache position of the resource to be requested in the cached resource list pool, and realizing the resource sharing scheduling among multiple Web cache nodes by redirection.

Description

technical field [0001] The invention relates to a Web cache system, in particular to a Web cache resource sharing system and method based on the Http protocol and realized by using an intelligent parent node. Background technique [0002] Web cache (Webcache) is a caching system based on the Http protocol. The main function of the system is to cache static resources. When a user comes to visit, it judges whether it is a resource cached by itself. If there is a cache, it returns the resource directly to the user, otherwise The proxy user requests the resource from the origin site, returns it to the user, and judges whether the resource can be cached, and if so, caches it. The introduction of a Web caching system can play the following three roles: [0003] 1: Reduce the pressure on source site visits; [0004] 2: Reduce the outbound bandwidth of the source station and relieve the bandwidth pressure of the backbone network; [0005] 3: Since the CACHE system is often deploy...

AI Technical Summary

Problems solved by technology

Traditionally, the parent node mainly assumes the role of proxy, and its main function is to change the path taken by the user request. Although the child cache node and the parent cache node can also achieve a certain degree of resource sharing, it is only based on the two-level cache system. resource sharing, but cannot realize resource sharing in the global cache node

Because according to the existing parent node working mode, if resource sharing among all cache systems is to be realized, all cache systems use the same parent cache system. The disadvantage of this working mode is obvious, that is, all cache requests will Guided to the same parent cache system, the access pressure of the parent cache system will increase exponentially, once the parent node fails, the global cache system will be unavailable

Therefore, the traditional parent node working mode is not suitable for shared scheduling between caches
