We propose a novel scheme, called Content-based Multilevel Caching Policy (CMCP) for super-peer networks that support hierarchical P2P architecture. Peers share information according the content between peers and between shared files to self-organise into clustered groups. Simulation experiments show that the CMCP policy achieves significant improvements in terms of access latency and global cache hit ratio.
