【摘要】 <正>1.引言随着计算机技术和互联网的发展,出现了越来越多的基于IT的应用,它们在社会经济、科学研究、工业应用等领域中扮演着关键的角色。其中电子商务、网络游戏、消息传递、远程协作等等分布式应用要求分布式计算模式,同时又要保证各参与结点的自治性。另外一些应用,如基因分析、天气预报与气候预测、太空探测等需要超强的计算能力来处理海量的数据。对于第二类应用,仅仅依赖于硬件的传更多还原

【Abstract】 With the rapid development of computer science and Internet technology,more and more super-intensive computing and autonomously distributed computing applications come out, which need fully exploit the three Internet assets,i.e.,information,bandwidth,and computing resources to address by means of P2P computing model.In this paper,we first describe nature and potential advantages of P2P and compare it with C/S architecture and distributed database.Next,we describe its main technical challenges and database techniques in P2P systems as well as present main research fields.In the end,we discuss the related work and the future direction.更多还原
