摘　　要：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。With the emergence of control plane, the network element management of intelligent optical networks should be extended to support the instantaneous access of control plane and management plane. To meet this demand, a network element management server scheme, based on Client-Server model, was developed by integrating NMI-T (networks management interface-transmision) and CCI (connect controll interface). The system has multiple interfaces for instantaneous access. The distributed scheme has successfully served as the network element management system of the first ASON (automatic switched optical networks) test-bed in China. The minimum operations interrupt time in protection mode is 89 ms while that in restoration mode is less than 300 ms.
