The architecture for Multi Protocol Label Switching (MPLS) is
described in RFC 3031.  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 defines 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.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
