Novel cluster proxy server system for Internet applications

The population using Internet is increased rapidly in the recent years. Thus the network bandwidth is not enough accordingly causing the information transmitted by slowly. Therefore, the function of proxy server is more and more important. The cluster proxy server system is composed of many independent proxy servers which can enlarge the disk cache by combing each independent proxy server and balance them. Cluster proxy servers can provide a higher cache `hit rate' than any independent proxy server. In the traditional cluster proxy server schemes such as Internet cache protocol or Hashing Routing Protocols, clients can not select proxy server location dynamically and it will increase the time of searching the related documents. In this paper, a new cluster proxy server structure is proposed and called the dispatching cluster proxy server system.
