Multi-protocol Label Switching (MPLS)

Multi-protocol Label Switching (MPLS) is used for fast data packet switching and routing system, it provides a target network traffic, routing, forwarding and switching capabilities. More specifically, it has various forms of traffic management mechanisms. MPLS independent of the second and third layer protocols, such as ATM and IP. It provides a way to IP address mapping has a fixed length for the simple labels for different packet forwarding and packet switching technology. It is the existing routing and switching protocol interface, such as IP, ATM, Frame Relay, resource reservation protocol (RSVP), Open Shortest Path First (OSPF) and so on.
