【摘要】 随着Internet的飞速发展和普及,P2P技术逐渐受到重视,P2P技术成为计算机网络技术中的一个热点。P2P模式与C/S模式相比较,减轻了服务器的负载并且减少了网络拥塞;改变了客户机在C/S结构中是被动的角色,使得客户机在P2P网络中成为同时具有服务器和客户机功能的节点。也就是说网络应用的核心从中央服务器向网络边缘的终端设备扩散。由于P2P模式的特点,P2P模式可以作为C/S模式很好的补充。 JXTA(juxtapose的缩写,指并行)是Sun公司于2001年四月份提出的,主要用于提供P2P程序所需的基础服务。该技术致力于创建一个通用的平台,以简单而有效的方式构建特定的对等式和分布式服务与应用。 本文首先概述了P2P的定义,技术特点和应用范围等一系列问题。随后对JXTA平台作了一些深入的探讨,并详细分析了整个JXTA协议架构和应用特点,为以后的设计打下基础。接下来给出开发实例—一个对等共享浏览器。最后简要的进行了总结,并对课题做了展望,指出了进一步研究的方向。更多还原

【Abstract】 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.更多还原
