MPLS Multiple Protocol Label Switching 2003/2/19

Key Terminology in MPLS FEC (Forwarding Equivalence Class) A group of IP packets which are forwarded in the same manner (e.g., over the same path, with the same priority and the same label) Label A short fixed length identifier (virtual circuit ID localized) which is used to identify a FEC Label Swapping Looking up the incoming label to determine the outgoing label, encapsulation and port Label Switched Path (LSP) Path through one or more LSRs for a particular FEC Label Switching Router (LSR) An MPLS capable router

MPLS Related Protocols Data forwarding Label encapsulation Label operations: PUSH, SWAP and POP Label distribution protocols Provide procedures by which one LSR informs another of the label/FEC binding Extensions to routing protocols Existing routing protocols can be extended to distribute traffic engineering information

What is a Label The label can be carried in a layer 2 header (e.g., ATM and frame relay) or in a “shim” that sits between the layer 2 header and IP (e.g., LAN and PPP) Exp: Experimental (3 bits) S: Bottom of label stack (1 bit) TTL: Time-To-Live (8 bits) PayloadIP“shim”Layer 2 Label value (20 bits)ExpSTTL 4 Octets
