ABSTRACT:
Multicast video services are provided in a network having a star topology. The network illustratively compromises a switched hub having a shared transmission medium and a plurality of ports. An Ethernet segment is connected to each port. Client stations belonging to the Ethernet segments communicate to the associated ports information identifying the particular multicasts they wish to receive. This is accomplished by sending special packets (mask update packets) from the client stations to the ports. Only multicast video data packets belonging to multicasts identified in the update packets are transmitted by the ports on the associated Ethernet segments.
