Analysis of traffic engineering parameters while using multi-protocol label switching (MPLS) and traditional IP networks

Traffic Engineering is a subject which ensures the utilization of your resources at their optimum level. In order to uplift the traffic engineering in our today networks, Multiprotocol Label Switching (MPLS) is being used which is very helpful for reliable packets delivery in recent internet services. It ensures high transmission speed, efficient utilization of bandwidth and lower delays during delivery of packets from one location to another. The purpose of MPLS in traffic engineering is to employ the networks as well as network resources efficiently. Based on lower network delay, capable forwarding means, scalability and expected performance of the services given by MPLS technology indicates its significance for implementing real-time applications i.e Voice & video. The salient of the thesis is to indicate the shortcomings of traditional IP networks vis-à-vis benefits of MPLS networks. The comparison analysis is based on the traffic engineering parameters such as delay variation, effective utilization of bandwidth, Jitter, Quality of Service (QoS), data loss and congestion etc. The results of the comparison revealed that traffic engineering through MPLS networks has enhanced reliability, scalability and other parameters as compared to traditional IP networks. In this thesis, Graphic Network Simulator (GNS3) has been used for simulation purpose to ascertain the results of both networks. KeywordsMPLS, Traffic Engineering and Graphic Network Simulator (GNS3).
