用光监控通道实现WDM网络的管理

WDM Network Management with OSC

比较了WDM网络特征信息的几种传输方法,给出了适合在监控信道中传输的开销内容。在此基础上,以城域WDM网络为例,给出了OSC中各种开销的处理过程和城域WDM网中OSC子系统的实现实例。为了适应智能光网络管理的需要,未来的光监控通道需要大约100Mbps的带宽。

How to transport the control and management information of optical network is a major concern these days. There are several means developed to transport them: including in-band and out of band methods. We compare them and arrive at a conclusion that OSC (optical supervisory channel) is a better choice. Then we deal with the content of OSC, which is independent from the data bearing system. We illustrate an OSC example of WDM metro network, which demonstrates the processing operation of overheads in OSC. At last, we discuss the future trend of OSC.
