Simulation and analysis of an admission control mechanism for MPLS DS-TE

Providing quality of service (QoS) is one of the main challenges in the internet that has recently gained the interest of many researchers. The internet architecture was originally designed to provide IP based “best effort” services to all its applications. The best effort service could be acceptabl...
