Next Generation Transport Network: MPLS Review The Key Difference Between Traditional IP Routing and MPLS Approach

Abstract
Multi-Protocol Label Switching (MPLS) is significantly emerging as an Internet Engineering Task Force (IETF) standard designed to enhance the service provisioning capabilities, speed and scalability in the Internet. MPLS packet forwarding technique is based on labels for the implementation of a simpler high-performance packet forwarding engine. It de-couples packet forwarding from the technique of routing, facilitating to provide varied routing services independent of the packet forwarding paradigm. We track the evolution of this technology in relation to other existing technologies. Then an overview of the MPLS architecture, operation is provided. This article reviews the comparison between traditional IP routing technique and the MPLS approach and identifies where MPLS adds value to IP networking. Keywords - MPLS, Packet forwarding, IP routing, Internet.
