abstract = {Generalized multiprotocol label switching
(GMPLS), optical packet, and burst-switched networks in which the synchronous
digital hierarchy/synchronous optical network (SDH/SONET) layer is removed may
be rendered nonfunctional because the current standard for triggering Automatic
Power Reduction (APR) cannot distinguish between a fiber that has been
de-energized and a fiber failure. If this standard is applied, without
modification, the likelihood of unnecessary amplifier shutdown in optical
networks is significant. These shutdown events may impact large regions of the
network and render optical links inoperable. To avoid unnecessary amplifier
shutdown, amendments to the current operation of APR are suggested.}
