This draft describes requirements for control plane-based recovery
from data plane failures 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 recovery from failures - using either a protection or
restoration scheme. Achieving recovery under strict time constraints
is a difficult problem. Shared mesh-based recovery is especially
desirable for reducing spare capacity ratios and achieving flexible
recovery scenarios. Following a brief overview and consideration of
the requirements, they are presented in an itemized list in section
3.4 of this document.

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
