Abstract

In dense-wavelength division multiplexing (DWDM) networks, one of the critical issues is routing and wavelength assignment (RWA). And, guaranteeing network survivability is essential for sustaining traffic continuity even for network failures. In this paper, we propose the routing algorithm called survivability-guaranteed minimum interference path routing (SG-MIPR). And under SG-MIPR, we suggest a joint path search approach using shared risk link group (SRLG) information, while considering trap avoidance (TA) problem. The effectiveness of the proposed algorithm is verified through the simulation experiments.
