Wavelength Assignment for Dynamic Traffic in Multi-fiber WDM Networks
Wepropose an on-line wavelength assignment algorithm for multi-jiber WDM networks, in which lightpaths are established and released dynamically. For a given number of jibers per link and number of wavelengthsperfiber, the algorithm aims to minimize the blocking probability. It may also be used to reduce the number of wavelengths required for a given tolerable blocking probability. Simulation results show that our wavelength assignment algorithm performs better than otherpreviously proposed algorithms (in the cases we studied). As the number of fibers per link increases, the benefit of having wavelength converters decreases dramaticulb, and thepevformance improvement of our algorithm over others increases. Our results also show that in case a preferred path is not available, rerouting along a node-disjoint backuppath can signijicantly reduce the blockingprobability.
