MPLS is widely deployed in operators Network in recent days as it is a matured technology now. In earlier days it was implemented cautiously, since the technology was new.
Unlike some of its precursors such as ATM and Framerelay, MPLS uses Control plane mechanism more effectively from the very begining.
MPLS overcomes several drawbacks of conventional networking technologies like speed, scalability, QOS and traffic engineering. MPLS provides a path for reveneue generation for service oriented operators by incorporating several applications over the MPLS backbone.
Before getting into the core concepts of MPLS, It is vital to understand the IP forwarding in traditional IP Networks. In traditional network, NLRI (Network Layer Reachability Information) is propogated using IP routing protocol. The packet forwarding decision is based on destination address only. Therefor when a packet is received by the router , it determines the next hop address by using packets destination address along with its own information that is in forwarding/Routing table.

IP/MPLS
I'm pleased and excited to write content on this topic. I am a systems integrator, I deal with all latest tehnology in the realm of Networking and Telecom. Recently I got fascinated by MPLS technology, which is a buzz word in the current IT industry. I am involved in a project which provides consultancy and management services to the client. This technolgy is fast growing and it is expected to surpass all the other legacy technology in the industry. I have decided to blog on this concept. My objective is to share knowledge related to this, So that it would benefit many technocrats all over the world.
