MVR Support Note

Overview of MVR

MVR refers to Multicast VLAN Registration that enables a media server to

transmit multicast stream in a single multicast VLAN while clients receiving

multicast VLAN stream can reside in different VLANs. Clients in different

VLANs intend to join or leave the multicast group simply by sending the IGMP

Join/leave message to a receiver port. The receiver port belonging to one of

the multicast groups can receive multicast stream from media server. In the

Figure 1, without support of MVR, the Multicast stream from media server and

subscriber must reside in the same VLAN. For each VLAN, A media server is

required to transmit multicast stream once and totally, media server transmits 6

times. In the Figure 2, on the contrary, with MVR, a media server is required to

transmit multicast traffic once to all the clients in different VLANs.
