Abstract

In this paper, a novel survivable algorithm with dynamic load balancing shared-path protection is proposed, named DLBSPP algorithm, in spectrum-elastic optical path networks (SLICE). To tolerate multi-link failures in SLICE, traffic self-adaptive restoration (TSAR) mechanism is adopted to restore the traffic affected by the failures. Simulation results show that, compared with the conventional SPP algorithm, DLBSPP algorithm has lower blocking probability (BP), better spectrum utilization ratio (SUR) and higher failure restoration ratio (FRR).
