Abstract

This paper presents a network re-optimization procedure moving the spectrum allocation of connections in a distributed fashion to defragment flexible optical networks, according to the proposed policies. Without changes to GMPLS standards, it improves network performance without traffic disruptions or excessive burdens for the control plane.
