Label switched path (LSP) backtrace is a method to backtrack the
paths followed by packets in a particular multi protocol label
switching (MPLS) forwarding equivalence class (FEC). This document
describes encoding and procedures for new label distribution protocol
(LDP) messages, backtrace message and backtrace reply message used
for performing LSP backtrace. Backtrace message is sent upstream for
an established LSP. Backtrace message can be used for LDP LSPs as
well as for constraint based label switched paths (CR-LSPs). Data
requested through backtrace message is encoded into backtrace reply
message. Backtrace reply message is sent in downstream direction. It
always travels towards the tail end of an LSP. Backtrace mechanism
described in this document can also be used for obtaining additional
attributes of LSPs.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
