A Novel Collaborative Caching Framework for Peer-to-Peer Networks

Caching is a well accepted method for curtailing the Internet traffic generated by peer to peer (P2P) applications. In general, any form of caching suffers from cache pollution. The pollution is severe in P2P cache system especially when the caches act collaboratively. This paper proposes a new collaborative caching framework utilizing intelligent cache updating scheme, for controlling the cache pollution, without compromising in performance. We validate the proposed system through simulations using real world data, in comparison with other caching algorithms. Test results indicate that the proposed framework drastically reduces the cache pollution compared to existing schemes.
