Relative cost routing and spectrum allocation in elastic optical networks

Elastic optical networks (EONs) are being used to adapt to the recent rapid changes in traffic behavior and the exponential growth in bandwidth demand. Routing and spectrum allocation (RSA) is one of the most important determining factors of the design, performance, and operation of EONs. In this work, we propose an adaptive RSA algorithm based on the relative cost concept under which the transient effect when a call is admitted on a given...
