This draft describes extensions to the Link Management Protocol (LMP)
for use in flooding-based fault notification in pre-OTN networks.
Pre-OTN networks are transport networks that have a GMPLS-based
control plane and various transport plane technologies (such as
Optical Cross Connects and Optical Add/Drop Multiplexers, etc.) An
important feature of these networks is timely recovery from failures
- using either a protection or restoration scheme. The recovery
schemes should also be resource efficient and flexible to meet
operator requirements. Once a fault is detected, fault notification
is one of a series of phases needed to achieve recovery. We prefer a
flooding-based approach to the notification phase because it may
offer speed and flexibility advantages over using RSVP-TE signaling
for notification. Extending LMP to include fault notification is a
good fit to the problem because fault management is already one of
its features and many of its protocol objects can be reused.

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
