Reactive Management of Quality of Service in Multimedia OBS Networks Based on GMPLS

This paper presents a proposal for dynamic control of Quality of Service (QoS) in optical networks based on optical burst switching (OBS) using a GMPLS control plane. In this proposal, monitoring agents are used to verify the QoS experienced by the burst classes and to deploy reactive mechanisms in order to guarantee absolute performance levels. Using GMPLS traffic engineering, these agents also offer idle resources to traffic flows whose service level is not being achieved. Simulation results show that the proposal can minimize the blocking probability when there are violations of burst flow parameters.
