摘　　要：互联网的迅猛发展,导致网络流量产生了爆炸式的增长。巨大的流量使得网络运营商面对着传输效率低下,带宽紧张等诸多问题。缓存系统的引入成为解决流量问题的主要方法。但是目前普遍采用的独立缓存系统,存在扩展性差,服务能力和缓存能力有限等问题,本文通过引入缓存间异构内容协同技术,可以整合多个分布式网络缓存系统协同工作,提高系统整体的缓存命中率,均衡各个缓存服务器的负载,有效地解决单点出错和流量瓶颈问题。The rapid development of the Internet has resulted in explosive growth of network traffic. Huge network traffic makes internet service providers faced with inefficient transmission, bandwidth tense and many other issues. Introducing caching system has become the main method to solve the problem. But now independent caching system, commonly used, have poor scalability, limited service ca- pacity and cache capacity and other issues. By introducing inter - cache content collaboration technology, the systems can work together to ensure that muhiple caches, improving overall system cache hit rate, balance the various cache server load, effectively solve the sin- gle point of failure and traffic bottlenecks.
