• Cache
• File popularity
• Load balancing
• Peer-to-peer (P2P) system
• Superpeer networks

The imbalance between local view of resources distribution and users' requests was the reason why performance of peer to peer systems decrease. A fingers and files double cache method for super-peer networks was presented. Based on local file popularity statistics, the fingers of interests were dynamically cached to the native super peers; it consequently extended peers' view of resources distribution globally. Files of high requests were also cached; local users could access the hot files from the native super peers. The experiment results show that the double cache method can dramatically improve the requests efficiency and download speed of the peer-to-peer system, and can effectively reduce the request load of hot spots.
