Title: Fault Notification Protocol for GMPLS-Based Recovery
State: Active
Authors: Richard Rabbat
Group: Individual Submissions (none)
Date: 2004-06-01
This draft presents a fault notification protocol for use in a GMPLS- based
failure recovery scheme. The protocol guarantees recovery path(s)
activation in a bounded time in the event of single resource failures.
These failures include fiber cut, transponder failure and node failure.
Bounded recovery time is achieved by pre-signaling recovery paths whose
nodes can be reached within a specific time, based on the physical
capabilities of the nodes and the delay characteristics of the control
plane. We propose using a flooding protocol for fault notification to allow
for per-failure notification and to speed up the recovery process. We
justify choices made for the notification method and the messaging required
for the protocol. The draft does not mandate a specific implementation of
the Fault Notification Protocol.
