An enhanced route assignment mechanism in optical control plane

No doubt, there is a need to introduce intelligence into the control plane of the optical network to provide dynamic and real-time provisioning and effective survivability. However, the traffic pattern migration from static to dynamic gives rise to many challenging issues. One such issue is the route assignment. For static traffic, the route assignment can generally be optimized using a variety of offline algorithms. For dynamic traffic, however, such a global optimization is impossible. Nevertheless, it is possible to perform individual optimization for each new call in the dynamic traffic pattern. In this paper, we propose an enhanced route assignment mechanism for the optical control plane and evaluate its performance benefits.
