Multiprotocol Label Switching (MPLS) is a method for forwarding
packets that uses short, fixed-length values carried by packets,
called labels, to determine packet nexthops.  A fundamental concept in
MPLS is that two Label Switching Routers (LSRs) must agree on the
meaning of the labels used to forward traffic between and through
them.  This common understanding is achieved by using a set of
procedures, called a label distribution protocol, by which one LSR
informs another of label bindings it has made.  This document
describes the applicability of a set of such procedures called LDP
(for Label Distribution Protocol) by which LSRs distribute labels to
support MPLS forwarding along normally routed paths.

This document is a product of the Multiprotocol Label Switching
Working Group of the IETF.
