摘　　要：JXTA协议在现有的物理网络基础上建立了一个虚拟的P2P网络,汇聚对等体是给其它对等体提供网络中节点位置和资源信息的节点。文章针对现有汇聚对等体节点组织机制的不足,引入信息熵概念,提出对对等体数目进行控制的对等体节点自组织机制,保证了网络查询的效率,使得P2P网络对等体节点的优越性能能够得到充分的发挥。JXTA protocols build a virtual network on the physical network, in which the rendezvous peer is a node to offer node position and resource information for another peers. This article aims at the deficiency of the rendezvous peer management mechanism. We use the information entropy to propose self-organized rendezvous peer mechanism which could control rendezvous peer＂ number. Query efficiency is ensured that there are some advantages of the P2P network with super peer sufficiency.
