Design And Implementation Of2P Cache Speedup System In IP Metropolitan Area Network

With the BT, e-Mule, Skype, the popularity of P2P applications, P2P technology has become an important part of the Internet, even many people have believed that P2P technology will become the development direction of future internet. As a client/server model completely different technology, the salient features of the P2P technology is:to the center in the P2P network, cyber source and service spread in the whole network, the logical status of each node is equal, have characteristics of both the client and the server, at the same time as the service consumer and service provider.The popularity of P2P applications from P2P technology provides unlimited service capacity, low cost and good service stability. The P2P system capacity increases with the number of users, in theory there is no bottleneck, on the contrary, the traditional client/server systems are unable to break through the bottleneck of server performance. In breaking the server bottleneck after the use of P2P technology can set up service at very cheap equipment, which brought the cost advantage. And all in P2P system peer end sharing service ability, single peer failure does not cause system crashes, to solve the traditional server client/server fault system may be caused by the collapse of the problem of service. In recent years, the number of users and the flow of P2P application are the explosive growth of the number of users, as of the end of2005, China P2P streaming media business has reached2350000,176%growth over the year.The deployment of accelerating system flow cache through exports in the operator’s network, through the P2P cache to accelerate system can control the P2P flow and P2P flow to the local cache buffer pool, and user access is redirected to the local cache pool, accelerating the user experience, reduce the total flow network capacity and improve the customer satisfaction objective.According to the "combined dredge, use" thought, P2P user behavior management can do the following:1、Export restrictions on the application of P2P 2、The P2P flow localization3、Increase of P2P content analysis, accurate grasp of user behavior4、Increase the service network video based on P2P, the new P2P value added services...
