“…Reference [18] investigates load intensity fluctuations of daily traffic and proposes a new dynamic line rate assignment heuristic using PAL shared protection SRRWA for dynamic traffic on transparent MLR networks. Comparison results show that the proposed strategy has an average performance while the highest resource utilization and lowest cost values are obtained from the static rate matching [5] line rate assignment method.…”

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.INDEX TERMS MLR, optical WDM networks, routing, rate and wavelength assignment (RRWA), shared backup protection, survivable communication.

“…The results show that there is a strict relation between strategy selection and resource utilization performance. Although there are numerous works on SRRWA problem [1], [2], [14], [18]- [22], to the best of our knowledge, there is no work that compares different strategies to improve sharing performance in MLR networks.…”

In this paper, we investigate the effect of path establishment method priorities over routing performance in mixed line rate (MLR) wavelength division multiplexed (WDM) optical networks. The survivable routing with rate and wavelength assignment (SRRWA) problem is presented and an efficient shared backup path protection solution is proposed. We prepared detailed simulation scenarios with all possible prioritizations and observed their performances. The simulation results show that assigning higher priority to single hop methods as compared with multi-hop methods yields better performance. In both methods, it has been observed that assigning higher priority to grooming reduces the communication cost and the traffic blocking ratio while enhancing the resource utilization.
