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 belongs to one of the multicast group 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 clients in different VLANs.
