A Routing and Wavelength Assignment Algorithms Based on the State Level of Links

摘要

For the problem of routing and wavelength assignment in Wavelength Division Multiplexing(WDM)optical transport network, an algorithm based on the state of links is proposed, which is named Tradeoff _LSDRAW, and which can select a path with the higher state level between a pair of nodes in a network. Finally, by a example network, we show that the algorithm has the stronger capability of selecting a better path between a pair of nodes, and can achieve the load balancing and reduce the congestion probability in WDM optical transport networks.
