由于在智能光网络中引入控制平面,网元管理需要同时支持控制平面和管理平面的接入。该文针对这种变化,参照Client-Server模型设计了将网络管理接口和连接控制接口整合在一起的网元管理服务器。据此提出了一个分布式、多接口、支持并发接入的智能光网络网元管理解决方案,并在中国第一个具有自动交换光网络功能的光网络实验床上得到了验证。其业务中断时间在保护模式下最短达到89ms,而在恢复模式下可达300ms以下。
Due to the introduction of the control plane in the intelligent optical network, NE management needs to support both the control plane and the management plane. In view of this kind of change, this text designs the network element management server which integrates the network management interface and the connection control interface with reference to the Client-Server model. Accordingly, a distributed optical network management solution with multiple interfaces and concurrent access is proposed and validated in China’s first optical network experiment bed with automatic switch optical network function. The business interruption time in protected mode, the shortest reach 89ms, while in recovery mode up to 300ms.
