面向下一代网络业务的应用支撑环境浅析

针对当前国内NGN产业正处于从初始的NGN试验起步阶段逐渐进入到NGN实施展开新阶段的重要过渡期，基于NGN 新业务的应用需求才是主宰NGN 发展原动力的产业发展原理，对NGN 业务较传统网络业务所具有的创新特征以及现有的应用支撑环境在NGN新业务的实际应用中突现出的技术缺陷进行了分析。在此基础上提出，面向NGN 业务的应
用支撑环境建设需在IP 协议体系、路由功能、组播方式和QoS 等四个方面引入新的技术机制，并就引做了深入讨论。

Abstract At present, NGN industry of China is in an important period, transiting from actual
experiment of NGN into implement of NGN. On the basis of the theory that the application
demands for new service of NGN are pushing NGN industry forward ultimately, the innovative
attributes of service of NGN, compared with that of the traditional network, and the
disfigurements of existing application-supported environment in developing service of NGN are analyzed. Grounding on these, this paper points out that new schemes in IP、routing、multicast and QoS should be introduced into the establishment policy of the application-supported environment for services of NGN , which are discussed deeply in the following part .
