CCAMP draft-bala-restoration-signaling-00.txt
NAME OF I-D:
http://www.ietf.org/internet-drafts/draft-bala-restoration-signaling-00.txt
SUMMARY
Restoration of switched connections under tight time constraints is
a challenging problem in optical mesh networks. This draft describes
different protection modes for connections under both local and end-
to-end restoration scenarios, and defines lightweight protocol
mechanisms (over IP) for restoration-related signaling.

This draft belongs in CCAMP, as it fits the description of
a CCAMP mechanism to *control* optical technologies, specifically,
the automatic connection restoration feature.
WHY IS IT TARGETED AT THIS WG
This draft directly addresses the "signaling mechanisms" part of
following item from the CCAMP charter:
- Abstract link and path properties needed for link and path protection.
Define signalling mechanisms for path protection, diverse routing and fast
path restoration. Ensure that multi-layer path protection and restoration
functions are achievable using the defined signalling and measurement
protocols, either separately or in combination.
JUSTIFICATION
Please see above for how this draft fits within the charter
of the CCAMP WG.
