摘　　要：为了考察基于WDM的光纤网络中动态波长分配方案,文章把目前应用较为广泛的波分复用无源光纤接入网作为研究对象,利用自相似的流量仿真理论建立流量仿真模型,对波分复用中静态和动态波长分配方案进行评估。结果说明采用动态波长分配方案在优化网络结构、应对网络中突发流量、均衡负载、降低信元丢失率以及提高服务质量等方面具备的明显优势。In order to evaluate the advantage and disadvantage of dynamic wavelength assignment based on WDM optical network, the article utilizes self-similarity traffic theory to produce traffic simulation model and analyses the scheme of static and dynamic wavelength assignments. As a result, it shows that the scheme of dynamic wavelength assignment possesses the obvious advantages in optimizing network structure, dealing with burst traffic, traffic load balance, debasing cell-loss ratio and improving QoS etc.
