Abstract
Embodiments may comprise a cable network that shifts control plane functionality for multicast sessions to a cable modem termination system allowing multicast without a cable modem snooping messages from a coupled device. Another embodiment may comprise a network including a device to generate a request to join a multicast session over a cable network, a cable modem termination system in communication with the device, the cable modem termination system to receive the request from the device and to generate a flow identifier to associate with the multicast session, and a cable modem in communication with the cable modem termination system and the device, the cable modem to receive the flow identifier from the cable modem termination system and forward the multicast session to the device from the cable modem termination system based on the flow identifier. Other embodiments may comprise an apparatus that has a port to receive a request from a cable modem to join a multicast session, and circuitry to generate a flow identifier to associate with the multicast session and communicate the flow identifier to the cable modem to allow the cable modem to forward the multicast session to a de…
