基于软交换的下一代网络技术

Next Generation Network Based on Softswitch

虽然因特网发展快速,丰富多彩的数据型业务不断涌现,但受制于现有的电信网络和IP网络结构及技术,使如何开拓更多更丰富的服务成为当前的主要问题,而下一代网络(NGN)技术就是这些问题最佳的解决方案。本文介绍了下一代网络的基本概念和特点,分析了下一代网络的框架结构,其核心技术软交换(Softswitch)和相关协议,以及存在问题及发展前景。

With the quick development of Internet, plentilu] traffics for data has emerged, but limited by the construction and technology of today's electric network and IP network, how to develop more plentiful traffics has been the main problem, NGN is the best version to solving these problems. In this paper, we demonstrated some facts on NGN, such as definition, character, system constitution. At the end, the future of NGN is discussed.
