Research of Replication in Unstructured P2P Network

P2P network is a great innovation makes computing and data transmission more efficiency and convenience. With the rapid development of P2P network, many problems appear to our sight. Nowadays, most of studies focus on routing algorithms and structured topology of the network, but ignore the foundation: the replication mechanism. In the paper, our research is based on the sub dividable area. We propose a new mechanism calls junction replication method (JRM) in unstructured decentralized P2P network which reflects the most usual P2P network in the real environment. With the method, we can achieve better load-balancing by reducing information flow. We also suggest using JRM to decrease the value of supernode to balance the traffic in network and improve the stability of the network. We compare JRM with others popular replication mechanisms, give pseudo code of the algorithm and prove the advantage by figure in the paper.
