摘要
介绍IP电话标准H.323的体系结构,指出了其体系结构中存在的一些缺陷。随后作者借用ESTI TIPHON所提出的H.323网关分解模型,加入新的实体域定制服务器,提出了一个改进模型,并对新的地址解析机制及服务定制机制进行分析,最后给出了一个应用实例。
This paper introduces in detail the architecture of H.323 firstly, which is a kind of Internet telephony standard, and pinpoints several pitfalls existed in it. The authors borrow the H.323 gateway functional decomposition model proposed by ESTI TIPHON, add a new entity, zone customization server. Then the authors put forward an improved model with instrumental arguments about new addressing mechanism and service customization mechanism, and finally give an example.
