Performance evaluation of IP network and MPLS network using NS2 simulator

Now a day in the internet service reliable delivery of packet is main issue. MPLS is such technology that assures about reliable delivery of the Internet services and also provides high transmission speed and minimum delays. To provide reliable delivery of packets MPLS technology includes a mechanism in which switching of data packets can be done on the basis of labels rather than routed on the basis of destination address. Due to this technology MPLS provides minimum network delay, efficient forwarding mechanism, scalability and predictable and makes it more suitable for implementing in real-time applications such as Voice and video. In this paper performance of MPLS based network is compared with conventional Internet Protocol based network. Network Simulator NS2.34 is used to simulate the both networks and the comparison is made based on the metrics such as packet end-to-end delay, packet send and received. The study results and the practical implementations show that MPLS based network provide much better results than simple IP based network.
