Özet
Design of shared backup algorithm in wavelength division multiplexed (WDM) mixed line rate (MLR) optical networks involves numerous attributes together with numerous heuristic alternatives. This study aims at identifying the pros and cons of these alternatives together with examining their performances. For this purpose, performance metrics that characterize sharing are first developed. Joint performance of shared backup metrics and other already existing network metrics is examined extensively throughout simulations. Among the strategies examined, the ones that yield best results are reported. Moreover, the topological dependence of these chosen strategies is discussed by simulations carried out on two popular characteristically different optical networks.
