2、e calculation of the problem.1 JXTA research project,which will provide a new framework that make the user more convenient to access to connect on the Internets personal computer resources, thus further expand Internet s space. At the same time JXTA is also the Suns ONE Internet strategic continuanc

JXTA agreement defines a set of six agreement based on XML, the organization of node into node group, release and found some resources, communication and mutual monitoring provides standardi

5、 points to send general inquiries, and receive the response of inquiries. (Peer Discovery Protocol, PDP) is used to release and found advertising resources. (Peer Information Protocol, PIP) used to get other nodes state Information. (Peer Binding Protocol, PBP), can let a node with another node or b

6、etween more nodes to set up virtual communication channel or pipeline. Compared to the nowadays general communication mode .P2P has many advantages, but it also has a lot of problems waiting to be solved.Firstly, each Peer in P2P is an active participant,in order to make the network performance incr

7、ease, they need more Peers participation, so that will result in the networks huge, manage this network will is a complex project; Secondly, P2P agreement compares with traditional client/server agreement it need more interaction, such as Peer join or exit network,but these factors 整理为word格式will cau

8、se some negative effect on network performance. JXTA是Sun公司首席科学家Bill Joy二十多年酝酿的结晶。“JXTA技术是网络编程和计算的平台，用以解决现代分布计算尤其是点对点(Peer to Peer,P2P)计算中出现的问题。”1JXTA研究项目，将提供使用户更便捷地访问连接在互联网上的个人电脑资源的新框架，从而进一步拓展互联网的空间。同时JXTA也是Sun的“ONE互联网”战略的延续，并且将以更积极的姿态与Microsoft的.Net战略和Hailstorm计划一争高低。 JXTA协议定义了一套基于XML的6个协议，对节点自组织成节

9、点组、发布和发现点资源、通信和互相监控提供了标准化的方法。端点路由协议（Endpoint Routing Protocol, ERP）用于节点发现路由，以向其它节点发送消息，并穿越潜在的防火墙和内网。集合点（Rendezvous Protocol, RVP）协议用于在节点组中传播消息。解析协议（Peer Resolver Protocol, PRP）用于向一个或多个点发送普通查询，并接收查询的响应。发现协议（Peer Discovery Protocol, PDP）用于发布和发现资源广告。信息协议（Peer Information Protocol, PIP）用于获取其它节点的状态信息。节点绑定协议（Peer Binding Protocol, PBP），可以让一个节点与另一个节点或者多个节点间建立虚拟通信通道或管道。整理为word格式 相比于现在通用的通信模式，P2P有很多优势，但同时也有很多问题亟待解决。首先，由于P2P中每个Peer都是积极的参与者，为了使网络性能增加，就需要比较多的Peer参与，这样就会造成网络的庞大，管理这样的网络必然会是一项复杂的工程；其次，P2P协议比传统的客户端/服务器协议需要更多的“交互”，比如Peer加入或退出网络，而这些因素将对网络的性能造成一定的消极影响。 友情提示：本资料代表个人观点，如有帮助请下载，谢谢您的浏览！ 整理为word格式
