基于GMPLS的智能光网络生存性研究

Survivability of intelligent optical network based on GMPLS

智能光网络是在光路由和信令控制下完成自动交换连接功能的新一代光网络。在传输带宽和业务应用需求的双重驱动下,智能光网络作为光传送网的发展趋势正得到越来越多的关注。本文介绍并分析了目前智能光网络的结构特点,在此基础上引入了通用多协议标记交换(GMPLS)技术,最后提出并详细阐述了基于GMPLS的生存性方案。

Intelligent optical network(ION) is a new generation optical network which can realize automatic switching and linking function under the control of optical routing and signaling.As a developing trend of optical transmission network,it has become a focus due to transmission bandwidth and service application demand.The configuration characteristics of the current intelligent optical network are introduced and analyzed in this paper,and GMPLS technology is inducted.Finally,a kind of survival scheme based on GMPLS is put forward and explained in detail.
