|Title:||Policy-based Grooming In Optical Networks|
|Abstract:||In this work, we are taking into account the scenario with IP/MPLS client networks over an optical GMPLS network. Based on that, aggregating lower traffic flows (e.g. packet-based LSPs) within higher traffic flows (e.g. lambda-based LSPs) is considered an effective way to maximize the use of the optical network resources. Furthermore, there is a clear necessity to control the flows entering in the optical layer taking into account Service Level Agreements and differentiated services. In this paper we describe some policies and an architecture for policy-based grooming responsible for managing the installation and aggregation of packet-based LSPs within lightpaths (optical LSPs). By defining some policies the monitoring and the network planning can be specified in a higher level. The policies we have defined intend to reduce the optical network overhead to remove and reroute lower priority LSPs. The architecture presented here is composed of an Admission Control and a Policy Manager and the performed simulations indicated that the number of LSP removals is smaller when policies are applied.|
