Abstract

This paper investigates the dynamic survivable routing problem and proposes an effective path-based protection algorithm, called the dynamic joint routing approach (DJRA), to completely protect against double-link failures in meshed wavelength division multiplexing optical networks. In DJRA, each connection is assigned a primary path and two link-disjoint backup paths to tolerate the simultaneous failures of two arbitrary fiber links. In order to improve the algorithm performance, we consider three key issues: (1) sharing spare backup resources, (2) failure recovery time, and (3) trap-path avoidance. Therefore, compared to previous algorithms, DJRA obtains better performance and is also able to yield flexible trade-off solutions.
