Patent ID: 7301936

Claim:
A system comprising: a broadcast overlay network having a ring topology to carry traffic from a head-end network, the broadcast overlay network comprising a plurality of synchronous optical network (SONET) rings connected by at least one cross connect element, the plurality of SONET rings comprising an ingress Add-Drop multiplexer (ADM) to receive the broadcast traffic from the head-end network and a plurality of egress ADMs, the plurality of SONET rings comprising a first SONET ring and a second SONET ring, the first SONET ring having the ingress ADM; a dedicated data network separate from the broadcast overlay network and a legacy xDSL data network; a digital subscriber line access multiplexer (DSLAM) having a line interface and a network interface, the network interface in communication with one of the egress ADMs of the second SONET ring, the DSLAM to receive an Internet Group Management Protocol (IGMP) request message for a particular video channel from a customer premise via the line interface, to determine an availability of the particular video channel based on at least one of a group address and a class-D Internet Protocol (IP) address provided by the IGMP request, and to deliver the particular video channel from the network interface to the line interface; the DSLAM further to receive; from the customer premise via the line interface, a unicast request for a destination in the head-end network, and to deliver the unicast request to the dedicated data network; and the DSLAM further to receive from the head-end network via the dedicated data network, unicast traffic whose intended destination is the customer premise, and to direct the unicast traffic to the customer premise via the line interface.
