摘　　要：为了提高代理系统的整体性能，基于内部网络用户访问时间的局部性和相似性，并结合现有的分布式缓存系统，本文提出了一种新型的分布式代理缓存系统——双层缓存集群。双层缓存集群系统分为网内集群缓存层和代理集群缓存层，采用双层代理缓存结构，充分利用现有内部网络资源，分散了代理的负担，降低了代理之间的通信开销，还增强了缓存资源的利用率，提高了用户请求命中率，降低了代理系统的整体资源消耗。In order to improve the overall performance of proxy system, this paper combines with existing distributed cache system, and proposes a new distributed proxy cache system--double-layer cluster proxy cache based on the similarity and locality for users＇ access to the Interact. The dou- ble-layer proxy cache system includes the internal cluster cache and the proxy cluster cache, It makes full use of the local network resource and dis- perses the burden of the proxy by use of the double-layer proxy cache structure; also this structure reduces the cost of the communication, enhances the utilization of the cache, improves the hit rates and reduces overall resource consumption of the proxy system.
