Peer-to-peer based multimedia digital library

New developments in super peer based peer-to-peer (P2P) network and digital library techniques give us the inspiration of looking for an approach to combine the reliability and strength of server with the flexibility of P2P network in multimedia data sharing. In this paper we describe the design issues of a peer-to-peer based multimedia digital library. Its design is based on super peer based P2P network using HyperCuP topology. Peers build local digital library. They publish their local data in network by interoperating with other peers through open archive initiatives (OAI) interface. I-super-peers process user request and find all available data. G-super-peers generate distributed caching and streaming plan for user data request The plan should be an optimized plan such that it would increase overall performance.
