Abstract

In one example, an Edge Quadrature Amplitude Modulation (EQAM) communicates EQAM information to a Modular Cable Modem Termination System (M-CMTS) core using a routing protocol that is configured on a packet switched network coupling the EQAM to the M-CMTS core. The EQAM generates a routing message according to the routing protocol and inserts EQAM information, such as a description of a modulated channel extending from the EQAM, the service-group information, etc, into the routing message. The EQAM then floods the EQAM information over at least portions of a routing domain by transmitting the routing message to an adjacent intermediary device.
