Abstract :This paper studies the topologies of different P2P network, summarizes, analyses and compares of four P2P topologies and their information retrieval mechanism: centralized topology, decentralized unstructured topology, decentralized structured topology and partially decentralized topology. At the end, the paper comes up with the main problems P2P system be faced with, and its development trend.
