The P2P network is a logical overlay network built up by the application software on the basis of IP network. The topology of P2P network refers to the physical or logical interconnection between computing units in distributed system, the topology between the nodes has been an important basis for determining the type of system. This kind of structure allows the client in a network to share some of the computer resources, so that the computer can provide its own remaining free resources for other users. This paper will go in-depth discussion and research about P2P network structure and communication.
