| 摘 要： | 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。

| Abstract: | Defined by IETF （internet engineering task force）,the generalized GMPLS （multiprotocol label switching） protocols,as the control plane protocols for optical networks,promote the intelligentization of optical networks.RWA （routing wavelength assignment）,is one of the core technologies for intelligent optical network.This paper,based on the introduction of RWA algorithm and GMPLS protocols,analyzes the demands of different RWA algorithm and different RWA technologies for network information,describes the development of GMPLS standardizations for the solution of RWA problem.Finally,the encodings of network information related to RWA are discussed. |
