Adaptive Routing and Wavelength Assignment Algorithms in WDM Grooming Networks

针对具有业务量疏导能力的WDM网状网,研究了网络节点具有光收发器数目限制并且不具有波长变换能力时的动态选路与波长分配问题,提出了三种自适应业务量疏导算法。仿真表明联合选路算法比其他算法具有更好的性能。

Traffic grooming, which can effectively use lightpaths to transmit traffic streams, i.e., to multiplex many low-rate traffic streams into one lightpath to transmit, is gotten more and more research. In this paper, for a WDM grooming mesh network, with the constraints on the number of transceivers per node and wavelength continuity, adaptive routing and wavelength assignment problem is investigated, and some adaptive traffic-grooming algorithms are proposed. simulations show that joint routing algorithm performs better than others.
