Abstract The network nodes in a Peer‐to‐peer (P2P) system are aggregated at the application layer of the TCP/IP suite. because the application layer do not match the physical network, it reduced the performance of the application layer. To address the problem, this paper presents a community‐ based node aggregation algorithm in P2P networks. This algorithm takes into account the existing infrastructure of the community, the node to the existing network delay coding technology roadmap was used, Network nodes are divided into different communities so that the application‐ layer topology can be mapped to the physical‐layer structure. This algorithm is able to optimize the network utilization and provide insights for the theoretical research in P2P networks. Keywords Community; P2P; Overlay Aggregation Algorithm

Introduction Compared with the traditional distributed systems, the P2P network has many advantages and broad application prospects. All kinds of P2P applications emerge on the Internet, and the number of users has increased dramatically. It is reported that some 50% of the foreign network traffic is occupied by the P2P network trafficand forecast in the next few years, peer‐ to‐peer (P2P) network traffic will account for more than 70% of the network traffic (Ou Zhonghong et al., 2008) P2P network technology is increasingly applied in the field of military, commercial, government information, communications and other fields. Application of P2P network mainly includes the following several aspects: (Ou Zhonghong et al., 2008) (K.Aberer, M.Hauswirth, 2002 )files and content sharing, such as Napster, Gnutella, CAN, eDonkey, BT(BitTorrent) is the application examples in this regard also; peer‐to‐peer computing ability and storage sharing ability, For instance, SETI@home, Avaki, Popular applications such as Power;

collaborative sharing platform and services, such as JXTA, Magi, Groove, NET My Service; instant communication, including ICQ, OICQ, Yahoo, Messenger, MSN etc; communication and information sharing, such as CliqueNet, Crowds, Onion, Routing etc. In many problems of P2P network, it is a key problem how to construct the overlay network. Structure coverage network directly determines the P2P network system scalability, robustness, security and performance, therefore, it is the primary problem how to construct suitable overlay network in P2P network, only it is solved, research on other issues can be go on. Currently, the overlay P2P network mainly focus on distributed unstructured overlay network design, distributed structured overlay network design and semi distributed covering three aspects of network (Zhang guoyin, Lijun., 2013). (1) for mobile network distributed unstructured overlay network design mainly includes: (Niu XZ et al., 2010) propose a model of collaborative resource sharing among mobile nodes, the model of queuing theory and reliability theory to realize the prediction algorithm and the corresponding resource scheduling strategy based on the Gnutella protocol using; Li et al. Discuss the cross‐layer design problem in MANET (Li T et al., 2009) in file sharing, the network layer routing protocol AODV is extended to EAODV, and the Gnutella agreement in the flooding request replacement as a cross layer by layer and network layer, common to complete a file search operations; Shah proposed a cross layer design of unstructured overlay networks based on P2P applications (Shah N, Depei Q.A., 2010); literature (Mawji, A, Hassanein H., 2010) created network game model of Fabrikant et; Literature (Fabrikant A et al., 2003, Afzal M et al., 2011) presented a MANET in the creation of P2P network model. The model is a non‐ cooperative game model of complete information between nodes, then decide whether to establish a connection between nodes through the game, so as to
