Research And Realize Of P2P Technology Base On JXTA

With the rapid development and popularization of Internet, P2P attracts more and more people's attentions and becomes a hot spot in the computer network technology. To compare P2P model and C/S model, Reducing the server load and the network jam;Changing the passive role in C/S structure, the client has the server and the client function in the P2P network. In other words, the application core of network proliferates from the central server to the network edge terminal device. As a result of the P2P pattern characteristic, the P2P pattern may be very good supplement of C/S pattern.JXTA (the abbreviation of Juxtapose) is an open P2P project of Sun beginning at Apr.2001, which mainly provides the foundation service of the P2P procedure. The technology devotes to creating a general platform, by a simple but the effective way to construct specifically to the equality and distributional service and the application.Firstly, this article introduces the P2P definition, the technical characteristic and the application scope and so on. Secondly, it makes some thorough discussions to the JXTA platform and describes JXTA protocol architecture and characteristic, which will build the foundation for the later design. Thirdly, it shows particularly the design and implementation of P2P Share Web Browser. Finally, it briefly summarizes the research results and views the prospect of the topic, and gives the direction of the future work.
