摘 要: 本文介绍了P2P网络的定义、特点,以及主要应用如文件共享、多媒体传输、分布式数据存储、分布式 计算、协同工作、实时通信和搜索引擎等,并与传统网络在节点对等、资源分散、管理自治、拓扑结构、中心依赖、 实时、可扩展、资源利用等方面进行了比较,P2P网络在分布式计算、协同工作、多媒体等方面强大的优势肯定是今后 迅速发展的强大动力。然后,从P2P系统安全的角度,分析了P2P网络面临的挑战,阐述了构建安全对等网络是必然趋 势,必将会拥有广阔的前景。

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.
Keywords: P2P network;traditional network;system security;distributed;collaborative work
