摘　　要：随着对等网络(P2P)技术的广泛应用,人们对P2P应用模式的需求也越来越大。相对于传统的C/S模式,P2P具有非中心化、扩展性好、性价比高、健壮性强以及负载均衡等优点。越来越多的组织和个人将P2P技术应用于互联网文件共享领域。文中归纳了P2P技术的起源及其发展过程,分析P2P的分类及相关情况,介绍了P2P在各个领域的广泛应用以及P2P安全信任模型的发展状况。从P2P概述、P2P分类、P2P应用现状、P2P安全模型和P2P发展面临的问题这五个方面介绍了P2P的研究现状,探讨了其不足之处,并且分析其原因。给出了对P2P领域发展前景的展望。As peer- to- peer applications are widely applied, the demand for P2P application model is also growing. Compared to traditional client/server （C/S） model, P2P is off- center, scalability, high perfomance - price ratio, strong robustness, load balancing, and so on. Thus, more and more organizations and persons are applying P2P technology into file sharing field. Mainly concludes the original and development of P2P technique, analyzes catego~, of P2P network and other associations and introduces extensive applications of P2P technique in each field as well as the development of P2P trust model. Researches on P2P are introduced from five aspects in this paper. Additionally, some disadvantages of research on P2P are discussed and the causes are explained at the same time. Meanwhile, prospects of P2P field are shown as an end.
