Abstract

Admission Control and routing are key aspects in next generation networks supporting advanced Quality of Service and Traffic Engineering functionalities. However, traditional Traffic Engineering solutions usually rely exclusively on routing algorithms to achieve optimization in network resource usage, while Admission Control is simply limited to a local check of resource availability, without any optimization purpose. This paper proposes a novel approach for Admission Control in IP/MPLS networks, which applies at network edges by means of dynamic thresholds evaluated on the basis of network status. The proposed solution allows the achievement of more efficient usage of network resources, especially at medium/high load, with an increased robustness of the network and an overall performance improvement.
