Abstract:
This paper investigates the survivable routing in backbone optical transport networks with shared-risk link groups (SRLG) constraints, and proposes a new risk-level disjoint protection (RLDP) algorithm for provide different service level for different connection request. Compared with the conventional SRLG- disjoint protection (SDP) algorithm, RLDP performs better resource utilization and blocking probability. Simulation results are shown to be promising.
