Abstract: In this paper, we consider the problem of routing, modulation and spectrum assignment (RMSA) with holding time awareness in elastic optical networks. We consider a two dimensional schedule that maintains link resource usage in both spectrum and time domains, and we develop an RMSA algorithm that attempts to reduce resource fragmentation by scheduling requests in a manner that takes into account the holding time of each request. We examine the performance of the proposed algorithm through simulation experiments, and our results indicates that the proposed RMSA algorithm obtains high spectrum utilization and lower blocking probabilities compared to existing RMSA algorithms that do not make use of holding time information.
