下一代网络业务架构的探讨

随着网络技术的飞速发展,原有的网络已不能满足用户的需求。以软交换设备为核心,能够提供话音、视频、数据等多媒体综合业务,采用开放、标准的体系结构,能够提供丰富业务的下一代网络(NGN)应运而生,且一度成为人们关注的热点。文章通过对NGN业务演进策略的分析得出NGN业务架构应满足的性能要求,然后根据现有的各项NGN业务技术构建了NGN业务架构,实现了传统电信业务和Internet业务的融合。

With the rapid development ot network technology,the old network has not meet the needs of consumers. The next genaration network（NGN） based on softswitch equipments which can supply multimedia integrated services such as voice, TV, data and uses open and standard architecture has aroused general concern. In this paper, NGN service framework capability requirements are achieved by analyzing NGN service evolution policy .Then, according to NGN service technologies at present, NGN service framework is constructed, finally the traditional telcom services are converged with the Internet services.
