What is MPLS Technology?

Multiprotocol Label Switching (MPLS) is one of the central elements of next generation networks. It provides an IP-compatible, QoS-capable infrastructure that enables the convergence of voice, IP, ATM, Ethernet, and Frame Relay onto the same backbone network.

MPLS stands for “Multi-Protocol Label Switching”. MPLS is best summarized as a “Layer 2.5 networking protocol”. In the traditional OSI model:

  • Layer 2 covers protocols like Ethernet and SONET/SDH, which can carry IP packets, but only over simple LANs or point-to-point WANs.
  • Layer 3 covers Internet-wide addressing and routing using IP protocols.
  • MPLS sits between these traditional layers, providing additional features for the transport of data across the network.

How MPLS Works: Basic MPLS Concepts

  • MPLS Label Switched Path (“LSP”) is one of the most important concepts for the actual use of MPLS. LSP is essentially a unidirectional tunnel between a pair of routers, routed across an MPLS network.  The LSP is required for any MPLS forwarding to occur.
  • MPLS Router Roles/Positions: Label Edge Router (“LER”) or “ingress node” is the router which first encapsulates a packet inside an MPLS LSP. LER is the router which makes the initial path selection.
  • Label Switching Router (“LSR”) or “transit node” is the router which only does MPLS switching in the middle of an LSP. It is also called Egress Node or Egress Router. It is the final router at the end of an LSP, which removes the label.

MPLS can combine the intelligence and saleability of routing with the reliability and manageability of traditional carrier networks. It is the key to scalable virtual private networks (VPNs) and end-to-end quality of service (QoS).

Forwarding Equivalence Class (FEC) is a group of IP packets which are forwarded in the same manner (e.g., over the same path, with the same forwarding treatment)

A label in MPLS is a short fixed length physically contiguous identifier which is used to identify a FEC, usually of local significance.


How MPLS Works – Basic Concepts

  • MPLS router roles may also be expressed as “P” or “PE”:
  • Question 1: What are the terms “P” and “PE”?
  • Answer: “P” and “PE” are the terms which come from the description of VPN services.  “P” stands for Provider Router and “PE” stands for Provider Edge Router
  • A pure P router can operate without any customer/Internet routes at all.
  • This is common in large service provider networks.
  • A customer facing router which does label popping and imposition.
  • Typically has various edge features for terminating multiple services: Internet, L3VPN, L2VPN / Pseudowires and VPLS
  • Question 2: What is the term “CE”?
  • Answer: “CE” stands for the “Customer Edge”, the customer device a PE router talks to.

MPLS at IETF: Look at the Details of all the MPLS RFCs

The MPLS (Multiprotocol Label Switching) working group is responsible for standardizing a base technology for using label switching and for the implementation of label-switched paths over various packet based link-level technologies.  This includes procedures and protocols for the distribution of labels between routers and encapsulation
