基于GMPLS的SDH／SONET光网络控制平面研究

Research of SDH/SONET network's control plane based on GMPLS

针对传统SDH/SONET网络存在的问题,提出基于通用多协议标记交换协议(GMPLS)的SDH/SONET网络控制,以实现光环路自动生成、更新与拆除.同时,分析了基于GMPLS的SDH/SONET光网络控制所涉及的两个关键问题——路由问题与信令问题,并提出了初步解决方案.最后,通过GLASS仿真软件,开发相应节点仿真模块,验证了系统的可行性.

In order to solve the problems of traditional SDH/SONET network, GMPLS （ Generalized Multi -protocol Label Switching） is inducted into the network, which serves for the control of SDH/ SONET network so as to provide the auto - provision, update and detach of optical circuit. The two critical problems about the system, i.e. route and signal are discussed, and the primary solution scheme is brought forward in the paper. In the end, the feasibility of the system is tested by the GLASS simulation software, which is performed through the development of the corresponding node simulation model.
