| Abstract: This article introduces the definition and characteristics of P2P network as well as the major application in file sharing,multimedia transmission,distributed data storage,distributed computing,collaborative work,real-time communication,and search engines.It is also compared with traditional network in terms of node equivalence,resource decentralization,management autonomy,topology,center dependence,real-timeness,extensibility and resource utilization. The remarkable advantages of P2P network in distributed computing,collaborative work,multimedia and other aspects are definitely powerful driving forces for the rapid development in the future.Then from the viewpoint of P2P system security,this paper analyzes the challenges faced by P2P network,and expounds why the construction of security peer-to-peer network is an inevitable trend with a promising prospect. |
