EDGE ADMISSION CONTROL IN MPLS NETWORK
Admission control and routing are two key mechanisms for advanced Quality of Service (QoS) and Traffic engineering (TE) support in the data networks. However, traditional QoS and TE solutions usually focus exclusively on routing to achieve network resource usage optimization, while often neglect to give adequate attention to admission control. To provide a more comprehensive solution, a novel approach for admission control in MPLS network was proposed in Ref. 2, which can be applied at network edges to provide the necessary QoS. However, the previously proposed admission control algorithm favors the QoS traffic without considering the influence on the huge amount of existing best-effort traffics. In this paper, we propose a new approach of computing admission thresholds, which takes into account both the best-effort traffics performance and QoS traffics constraints. Simulation results show that our new framework can provide additional performance protection for best effort traffic and improve throughput performance of the entire network.
