Abstract

We propose a concurrent collision avoidance scheme based on wavelength rotation (WR) in optical WDM networks. By introducing wavelength cost during the path computation process, the proposed scheme can significantly reduce the concurrent blocking probability (BP), without introducing additional connection setup delay compared with the time-threshold- based concurrent RWA schemes.
