Traffic engineering is a topic which ensures the best possible use of the resources. Now to support traffic engineering in the authors' today's network, Multi-Protocol Label Switching (MPLS) is being used which is very helpful for reliable packet delivery in an ongoing Internet service. During the delivery of packets from one location to another, it ensures high transmission speed, efficient use of bandwidth and lower delays. MPLS is a process which depends on label switching for taking forwarding decisions. Label is created for every route in the routing table. This paper presents a general idea of the MPLS technology and how it is faster and better than traditional IP routing.
