Availability analysis considering primary and backup sharing in wavelength-division multiplexed networks
Author(s): Yonggang Li; Yaohui Jin; Lemin Li

Paper Abstract

In survivable wavelength-division multiplexed networks, the backup resource can be shared by the primary light paths, which is called primary-backup sharing. We find that primary-backup sharing can have an effect on the link availability. We focus on routing under dynamic availability of the wavelength resource while the requested reliability of traffic has to be met, using the modified shortest path algorithm. We propose a new algorithm called the dynamic link availability algorithm and evaluate the performance of the proposed algorithm on the NSFNET.
