Out-of-band communication channel for subcarrier-based optical communication systems

Abstract:

An example system includes a plurality of hub transceivers and a plurality of edge transceivers. A first hub transceiver is operable to determine that the first hub transceiver is configured to assign a first subset of network resources to a first subset of the edge transceivers for communication over an optical communications network, and determine that a second hub transceiver is configured to assign a second subset of network resources to a second subset of the edge transceivers for communication over the optical communications network. The first hub transceiver is also operable to determine that the first subset of network resources overlaps the second subset of network resources, and in response, transmit a notification of the overlap to a control module of the optical communications network.
