Abstract:
VPN networks running over MPLS have found widespread acceptance as both an efficient and cost effective means to provide connectivity for large organizations and companies. However, providing QoS is still a major challenge that needs to be addressed. Using realistic input traffic, a simulation model is built for a large network where various queueing policies are implemented and evaluated for the provision of certain QoS requirements. After a thorough analysis the merits and shortcomings of each policy are determined, and recommendations are given along with future research directions.
