摘　　要：RWA问题是静态环型波长路由光网络中的一个核心问题。随着RWA优化算法求解方式的简化,算法的运算效率得到了提高,但却牺牲了解的优化性能。如何使优化效率和时间效率协调统一是当前环网波长路由光网络中RWA优化算法设计的难点。本文对静态波长路由光网络中RWA问题进行了阐述,综述了当前国内外的RWA算法,并对静态环网中几种新的算法进行了分析研究。RWA is an important issue for static wavelength routing optical network. With the reduction of RWA optimum algorithm＇s solution method, the computational efficiency of the algorithm has been improved at desingning optimum performance. How to coordinate optimum efficiency and time efficiency is the difficult point for designing RWA algorithm in the wavelen the static wavelength routing optical netwo and presents some new algorithms gth rk, routing optical network. This paper tells of the RWA problem on summarizes the RWA algorithm at home, and abroad in recent years
