The Prospect Research of PS2P Download Technology

Abstract

In the 21st century,all kinds of information exists on the network.The network has become a very important part of the people's lives.Faced with

the number of information,different people demands different information. So,we need to use different download tools for us.

PS2P is further to spread of P2P.P2P is a network model rising in recent years.Compared with the traditional Client/Server model,P2P has many advantages, such as the higher utilization of network resources, the elimination of bottleneck caused by central servers. So P2P has great potential value on commerce and technology. This paper analyzes the characteristics of The Web Technology, P2P and PS2P, and then presents the stale of the art on research and application in detail of the PS2P technology. Analysis obtain the PS2P technology will become an essential download technique.
