MPLS Traffic Engineering in ISP Network

Multi Protocol Label Switching (MPLS) is an innovative and vibrant technology. The most famous applications of MPLS technology are MPLS VPN, MPLT Traffic engineering and MPLS QoS and Any Transport over MPLS (AToM). This study addressed only MPLS Traffic engineering, which is one of the driving factors of deploying MPLS in service provider networks. This research consists of two main sections; in the first section basic concepts of MPLS have been reviewed and in the second section, implementation of the MPLS based ISP network, configuration and verification of the results are covered. Simulation results show that on large service provider networks, no other technology can engineer traffic as efficiently as MPLS does. This research aims to provide guidelines for network engineers for efficiently engineering network traffic in the service provider network.
