Patent abstract
Methods and systems consistent with the present invention provide a way to provide optimal delivery of multicast content by retail ISPs in a wholesale aggregation network environment. A broadband network gateway dynamically informs an access node of a mapping between a multicast domain corresponding to the retail service provider, allowing the gateway to send multicast data to the access node for replication to subscribers instead of replicating the multicast data at the gateway. The gateway dynamically informs the access node of the mapping using a standardized access node control protocol. The gateway can also dynamically instruct the access node to update or delete the mapping.
