The multicast
feature of the MA5600/MA5603 is applied to the live TV and near-video on demand
(NVOD) multicast video services. The MA5600/MA5603 runs the IGMP proxy or IGMP
snooping protocol, and the interconnected device can run the IGMP proxy, IGMP
snooping, or multicast router protocol.
Currently, the
multicast application of the MA5600/MA5603 is oriented to L2, and the
MA5600/MA5603 forwards data based on VLAN ID+multicast MAC address. A multicast
program on the network is identified by VLAN ID + multicast IP address
uniquely. The MA5600/MA5603 differentiates multicast sources by VLAN ID. It
allocates a unique VLAN ID to each multicast source, controls the multicast
domain and the user right based on the multicast VLAN ID, and provides a
platform for different ISPs to implement different multicast video services.
