Abstract
We categorized synchronous optical network (SONET) operations, administration,
maintenance, and provisioning (OAM&P) requirements according to their time
urgency as related to the network operation and assigned them to a three-layer
telecommunications management network for transparent networks accordingly. Because
all-optical bit-by-bit processing at data rates is not yet available, a solution
that is currently feasible for optical management layer requirements is proposed on
the basis of a previously demonstrated advanced channel-monitoring method.
Indicators for signal quality as well as channel use can be provided, and the scheme
is transparent to current SONET network elements.
