摘要

综合接入媒体网关（AMG）位于基于软交换（SoftSwitch）的下一代网络（NGN）的接入层面

其高可用性（HA）直接影响着电信网络的服务质量。文章首先介绍了HA的概念及实现

然后通过对综合AMG的结构及功能的研究

提出了一种实现其HA的方案。在硬件部分

以主备方式的硬件冗余机制来实现硬件容错功能

关键数据及参数的备份均采用温备份方式。在软件部分

提出了实现HA的整体架构以及实现倒换的状态机制。

Abstract

The integrated Access Media Gateway（AMG） is placed in the access layer of the SoftSwitch-based NGN.Its High Availability（HA） has a direct impact on the QoS of telecommunication networks.The concept and realization of HA is first introduced and then an HA solution presented on the basis of the study of the architecture and functions of AMG.In respect of the hardware

its fault-tolerance function is realized by the active/standby redundancy mechanism with the critical data and parameters in warm standby

while for software

the over-all architecture for HA and the status mechanism for switchover are advanced.
