P2P 网络若干关键技术研究现状与展望

P2P技术在过去的十几年间迅猛发展，智能移动设备的普及以及人们对在移动环境中实现文件共享需求的不断增加，使移动P2P（MP2P）网络成为研究的重点。但由于MP2P网络的一些特性，很难在现有网络中实现基于MP2P网络的应用。本文在阅读大量文献的基础上，介绍了P2P网络的基本概念，分析了MP2P网络目前存在的一些问题，提出了相应的解决方法，使读者可以了解P2P这项技术的基本原理、研究现状及发展方向。

Research status and prospects of some key technologies of P2P network

P2P technology has developed rapidly in the past ten years,and as a result of the popularity of mo-bile devices and increasing demand for sharing files in mobile environment,mobile P2P network (MP2P) has become a hot topic in research area.However,due to some characteristics,it is difficult to achieve MP2P appli-cations in live network.On the basis of consulting a large amount of literature,this essay introduces the basic concepts of P2P network,analyses the existing problems of MP2P and puts forward some associated solutions so that readers are able to understand the principle of P2P technology,its research status and development di-rection.
