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.
