因特网工程工作组(IETF)制定的通用多协议标签交换协议(GMPLS),作为光网络的控制平面协议,推动了光网络的智能化进程。路由和波长分配问题(RWA)是光网络智能化的核心问题之一。在介绍RWA算法和GMPLS协议的基础上,分析了不同RWA算法、不同RWA机制对网络信息的需求,描述了GMPLS协议为解决RWA问题所做的标准化工作,并分析了与RWA相关的网络信息分发格式。
The General Multi-Protocol Label Switching Protocol (GMPLS) developed by the Internet Engineering Task Force (IETF) has promoted the intelligent process of optical networks as a control plane protocol for optical networks. Routing and wavelength assignment (RWA) is one of the core issues in optical network intelligence. Based on the introduction of RWA algorithm and GMPLS protocol, we analyzed the requirements of different RWA algorithms and different RWA mechanisms for network information, described the standardization of GMPLS to solve the RWA problem, and analyzed the RWA-related network information distribution format.
