Abstract: In this paper, a plan of system locating in IP telephony network with H.323 protocol is proposed. The prototype of plan is set up on the thread tree. The request of interaction between nodes will be delivered directly to their nearest co-ancestry node through thread in nodes and the job of locating will be done completely in its subtree. By this way, the time of system locating in operating system may he shortened significantly, and the burden of channel between domains may be reduced also.

摘要： 针对电信运营中分组实时语音网络存在的时延问题，基于Ｈ．３２３建议的ＩＰ电话网络体系，提出一种动态的系统寻址方案．系统原型建立在线索树上，结点之间的互访通过线索直接提交到最近共同祖先结点，在其子材内部完成最终定位．该方案可以减少整个系统寻址时间，极大地减轻域间网络负担．
