摘要
介绍了基于G.8032的以太网保护倒换中节点的状态机迁移规则,详细分析了单点故障下保护倒换与恢复机制。在此基础上,着重阐述了多点故障下的恢复方案。通过测试结果表明,该方案能很好地从多点故障中恢复原有的网络拓扑,满足电信级以太网的网络自愈时间要求,提高了以太网的可靠性。
The migration rules of node state machine which in the Ethernet protection switch based on G.8032 was introduced, the protection Switch and Recovery mechanism under a single-point of failure are analyzed in detail .On this basis, emphatically expounds the multi-point fault recovery program. Through the test results show that the scheme can well recover from failure to original network topology, satisfying the requirement of the carrier Ethernet network self-healing time and improving their reliability.
