Performance evaluation of multi-protocol label switching (MPLS) over IP

Networks have evolved in terms of infrastructure and configuration incorporating new technologies and adapting them to take account of the need for technicality and compatibility with the rapid changes taking place in the world. MPLS (Multi Protocol Label Switching) is a versatile solution (based on QoS) to solve the problems addressed by the present networks like IP (Internet Protocol). In this chapter, we evaluate IP /MPLS networks in terms of performance, using several criteria of QoS. These criteria include: delay variation (average delay and delay), through put and loss rates. We evaluate through several types of flow (data, voice, video). To simulate IP/MPLS topology, we use the NS-2 simulator.
