摘要
缓存服务器集群的适应性缓存策略能够根据用户访问模式,自动调整热点数据在缓存服务器中的分布情况。在分析原有适应性缓存策略之上,提出了一种结合了P2P技术的缓存服务器集群的适应性缓存策略,将热点数据向离用户较近的边缘缓存服务器推进,有效地均衡了整个缓存服务器集群的负载,提高了缓存服务器集群的边缘缓存字节命中率。
The strategy of adaptive caching in cluster-based caching system can regulate the distribution of the popular data in clusterbased caching automatically based on different users＇ access patterns. A special adaptive caching strategy is offered which contains a certain p2p technology in cluster-based caching system. It is able to push the popular data to the nearby-caches which is nearer to the users. In this way, the overall network load of the cluster-based, caching system is reduced effectively, and the percentage of nearby-cache-bitshits in the cluster-based caching system is raised as well.
