Recommendation ITU-T G.7716/Y.1707 addresses the architecture of control plane operations. Guidance for service providers on the automatically switch optical network (ASON) network plan, performing typical operations in the network, and sequencing the ITU-T G.7718.1 operations, are described in this Recommendation. This Recommendation also provides guidance to control plane function and protocol designers on the sort of operations control plane protocols and implementations that they need to be able to support.
