I-D ACTION:draft-ietf-mpls-ldp-ft-03.txt



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		: Fault Tolerance for LDP and CR-LDP
	Author(s)	: A. Farrel, P. Brittain et al.
	Filename	: draft-ietf-mpls-ldp-ft-03.txt
	Pages		: 52

MPLS systems will be used in core networks where system
downtime must be kept to an absolute minimum.  Many MPLS
LSRs may, therefore, exploit Fault Tolerant (FT) hardware
or software to provide high availability of the core
networks.
The details of how FT is achieved for the various
components of an FT LSR, including LDP, CR-LDP, the
switching hardware and TCP, are implementation specific.
This document identifies issues in the CR-LDP
specification [2] and the LDP specification [4] that make
it difficult to implement an FT LSR using the current LDP
and CR-LDP protocols, and proposes enhancements to the
LDP specification to ease such FT LSR implementations.
The extensions described here are equally applicable to
CR-LDP.

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.
