Evaluation of Quality-of-Service Support in MultiProtocol Label Switching

Abstract

The technology of MultiProtocol Label Switching (MPLS) represents one of the most advanced ways how to optimize the packet-forwarding process in routers. In addition, MPLS also offers new possibilities of resource sharing, important from the point of view of service differentiation and quality of service (QoS) support. The aim of the paper is to present the results of our investigation into the efficiency of QoS support mechanisms available in MPLS for different traffic types. For this purpose several simulation scenarios were built to obtain a complex overview of the topic examined.
