A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF.
Title : Time to Live (TTL) Processing in MPLS Networks
(Updates RFC 3032)
Author(s) : P. Agarwal, B. Akyol
Filename : draft-ietf-mpls-ttl-04.txt
Pages : 8
Date : 2002-12-2
This document describes TTL processing in hierarchical MPLS networks
and is motivated by the need to formalize a TTL-transparent mode of
operation for an MPLS label-switched path. It updates RFC-3032 'MPLS
Label Stack Encoding'. TTL processing in both pipe and uniform model
hierarchical tunnels are specified with examples for both 'push' and
'pop' cases. The document also complements RFC-3270 'MPLS Support of
Differentiated Services' and ties together the terminology
introduced in that document with TTL processing in hierarchical MPLS
networks.

In the body type:

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.
