| 摘 要： | 针对当前P2P缓存系统中存在缓存污染的问题,提出了一种新的缓存系统.在该系统中,网络边缘部署了超级跟踪服务器,根据用户对资源的访问特点,设定缓存优先级,对资源进行有选择的缓存,进而减少P2P缓存系统中的缓存污染.根据资源当前的热度,对LRU替换策略进行了改进,提出了一种新的缓存替换算法LRU-N.理论分析和仿真数据表明...

| Abstract: | Aiming at the existing cache pollution problem in P2P cache system,a new cache system was proposed.The super tracking servers were allocated in the network edge of this system,and according to the characteristics of user's access to resources,cache priorities of the resources were ranked,and then resources were selected into the cache so that cache pollution in the P2P cache system was reduced.Based on the current heat degree of resources,LRU replacement strategy was improved,and a new cache replacement alg... |
