Title : Recovery in Optical Burst Switching Network

Protection and restoration at optical layer is critical to network
integrity since data is transmitted and switched at a considerably
high speed in optical domain. A few second halt may cause tens to
thousands gigabit loss. Optical burst switching is a promising
technology, bridging optical circuit switching and optical package
switching. Unlike optical circuit switching and time division
multiplexing, OBS is featured with unidirectional reservation and
statistical multiplexing of wavelength resources. The general idea
behind protection and restoration techniques is to utilize redundant
bandwidth resources as backup. The flexibility brought by OBS
provides alternatives for existed protection and restoration schemes
at optical layer.

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
