MPLS (Multi Protocol Label Switching)
Multiprotocol Label Switching (MPLS) is a mechanism used in high-performance telecommunications networks which directs and carries data from one network node to the next. MPLS makes it easy to create "virtual links" between distant nodes. It can encapsulate packets of various network protocols in Label Switched Path (LSP) between two MPLS nodes like P (Provider equipment) or PE (Provider Edge equipment). MPLS is widely used by Telecom operators (TELCOs) to provide enterprise IP/VPN services.
