摘要：In order to solve congestion of IP over WDM network using time-division switching, and to meet the demands of different services, we presented a channel assignment scheme named queuing algorithm. The main idea was adding queuing caches and controller in each HUB, which can assigned wavelength channels and time-slots dynamically according to different transmission priorities, the higher the transmission priority, the better was the opportunity to be assigned more wavelength channels. The theory of this algorithm was introduced, and the performances were analyzed by building random queuing model. The results appear that it is an efficient way to improve QOS and the usage of wavelength channels with low latency.
