软交换技术所涉及的几个重要协议的分析与比较

Analysis and comparison of several important protocols involved by soft switch technology

随着Internet的新兴业务的快速发展,将进一步加快下一代网络的演进步伐。针对NGN所涉及的协议的规范与应用在向NGN的演进过程重要性,对基于软交换的NGN技术特点进行了概述,着重分析和比较了NGN所涉及到的几个关键协议,得出NGN相关协议优劣势,从而进一步明确了NGN的演进方向。

With the rapid development of new Internet businesses,the evolution of NGN will be quick. Thus the constitution and application of the relative protocols is a very important job especially during the evolution. The characteristic of NGN technology based on soft switching was briefly introduced,and several key protocols involved by NGN were analyzed and compared on emphasis. The advantage and disadvantage of the Several protocols are obtained to further clarify the direction of the evolution.
