This document provides the problem statement on a extra class LSP ser-
vice and addresses the issues. The extra class LSP uses the resource
reserved but not allocated for the protecting LSPs in the pre-planned
LSP re-routing without extra-traffic (including shared mesh) recovery
method. Network utilization is improved because the resource reserved
for the protecting LSPs are used for the extra class LSPs. The extra
class LSP is preempted less frequently than the conventional priority
mechanism using setup and holding priorities because the resource
reserved for the protecting LSPs is allocated only if the working LSP
fails, which is usually expected to rarely occur. This document pro-
poses the extra class LSP service using the resource reserved but not
allocated for the protecting LSP at the provisioning phase. This docu-

available resource, (2) extra class LSP indication in signaling message
(3) extra class LSP preemption signaling, and (4) preventing unintended

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.
