Abstract
Multiprotocol Label Switching (MPLS) is a technology developed to address the bottleneck of Internet Protocol over Asynchronous Transfer Mode network. It is a packet forwarding technology using labels to make data forwarding decisions. The use of label forwarding instead of IP address consumed a lot less resources in the old days as it was faster but nowadays the speed improvement is negligible due to new lookup table algorithm. However, it is one of the most utilized technologies among Internet Service Providers due to its Traffic Engineering (TE) capability. In this research, a deductive methodology has been used to evaluate the benefit of MPLS Traffic Engineering in the presence of traffic collision and we investigate how the implementation of Fast Reroute (FRR) helps to reduce the convergence time in case of link/node failure. Results show that TE helps to improve the quality of service in terms of latency in the presence of background traffic and FRR helps to reduce convergence time to less than 100 ms.
