摘　　要：在IP over WDM网络中,WDM光网作为底层传送网络,目前还不能完全解析IP层对业务QoS区分等信息。针对IP和WDM网络中两种不同的QoS机制,应用IP网络差分服务模式,通过UNI接口汇聚来自IP网络的流量,将其映射为光域中相似的业务需求,在光域中为不同QoS业务提供不同QoS保障的光连接通道,实现了WDM网络层的QoS区分服务。In the IP over WDM network, since the WDM optical network is the underlying transmission network, it can not fully analyze the QoS information of the business from the IP layer. For the two different QoS mechanisms in IP and WDM networks, the differential service model in IP networks will be applied in optical networks, the IP traffic flock together through the UNI interface, and the traffic will be mapped to the similar business needs in the optical domain. In the optical domain it provide different services for different QoS guaranteed optical connection channel. It realize QoS differentiated services in WDM network layer.
