A New Routing-Based Admission Control for MPLS Networks

In this paper, we propose a routing-based admission control mechanism for the IP traffic flows in MPLS networks. This mechanism is based on solving exactly a mathematical programming model including end-to-end delay constraints for all traffic flows. The numerical results show that considering end-to-end delay constraints for already admitted flows has not an important impact on the blocking rate but significantly reduces the mean end-to-end delay of each flow
