QoS and Traffic Engineering : MPLS , DiffServ and Constraint Based Routing

Providing Quality of Service (QoS) and Traffic Engineering capabilities in the Internet is very essential to support the requirements of current and future Internet services. MPLS and Diffserv show a lot of promise for making this a reality. Unfortunately, current network simulators lack a robust and coherent implementation of these technologies. The aim of this project is to deliver a complete and integrated simulation environment for ns-2 network simulator to facilitate research in next generation QoS and Traffic Engineering technologies, and to provide new views on the same.
