At the end of the chapter , the effort to improve the fairness of wdm networks with xgm wavelength converters is performed ; the result shows that it is not effective
第四章研究了备用路由与波长分配算法对有限范围波长变换器wdm网络的性能影响，主要是研究fwm和xgm波长变换器。
This paper is concentrated on the following three aspects : ( 1 ) the researches about limited - range wavelength conversion , the contents include : the research about the rwa ( routing and wavelength assignment ) of xgm ( cross - gain modulation ) wavelength converters ; the performance analysis of wdm network with limited - range wavelength converters , which includes xgm and fwm ( four - wave mixing ) wavelength converters ; the research about the influence of the alternate rwa to the performance of wdm networks with limited - range wavelength converters
