| 摘 要： | 共享缓存文件是减少网络通信量和服务器负载的重要方法，本文在介绍Web Caching技术及流行的Web缓存通信协议ICP的基础上，提出了一种集中管理式Web缓存系统，该系统通过将用户的HTTP请求，按照一定的算法分发到系统中某一合适的缓存服务器上，从而消除了缓存系统内部服务器之间庞大的通信开销及缓存处理负担，减少了缓存内容的冗余度．通过分析，证明了集中管理式Web缓存系统比基于ICP的简单缓存系统具有缓存效率高、处理开销低、延迟小等优点，并且该系统具有良好的可扩展性．

| Abstract: | Caching is essential to reduce network traffic and server load. A new concentrated management web caching system is proposed in this paper,which dispenses the client HTTP requests to a suitable web cache server according to a given algorithm. Therefore, the redundant content among cache servers are greatly reduced,the huge communication and processing costs of the cache servers are also reduced. In comparing with ICP web cache system, the web caching system is proved performances of access Internet, such as hit rate, processing cost and latency. On the other hand, the system could be smoothly expanded. |
