摘要
目前光网络的拓扑结构越来越复杂,逐渐向网状结构光网络发展。提出了一种新的网状光网络智能实时在线监测保护方案,该方案采用下层嵌入式监测设备+上层网管中心的模式。在嵌入式监测保护设备上加入保护光纤路由计算的功能,由嵌入式监测保护设备事先用路由算法计算出每条工作光纤的备用光纤路由,在工作光纤发生故障时及时进行切换。该方案实现了真正无人值守的光网络智能实时在线监测保护设备,适应网状光网络的发展要求,实现网状光网络的透明无阻断通信。
Abstract
At present, the topology of optical network becomes more and more complicated and is going to be the mesh structure. A new design of intelligent real-time monitoring and protection of mesh optical network is put forward in this article. In this new design, the monitoring and protection system is composed of the bottom level of embedded monitoring devices and the top level of network management center. The function of computing the protection fiber route is added to the embedded monitoring and protection device. The device figures out the backup fiber routes of each working fiber in advance, and switches to the backup fiber route in time while the working fiber fails. In the new design, a kind of real unattended intelligent real-time monitoring and protection device of optical network comes true, and it meets the requirement of the development of mesh optical network. The transparent uninterrupted communication of mesh optical network is achieved.
