Users use MA5200G+IPDSLAM (IGMP-PROXY) and form topology. After the service is open, buffer time is ong (about four seconds) when users change channels. Client want to reduce chagneover time.
Configure under relevant multicast interface of MA5200G: igmp host-join group-address command. Find MA5200G has built multicast route table and flood multicast traffic to IP-DSLAM. When changing chnnel, the time is reduced to 2 seconds.
When users change channels, IGMP REPORT packet sent by STB needs proxy and reports to MA5200G. Build multicast table at MA5200G上 and flood multicast traffic. The process is long and buffer of channel changeover is long.
Configure under relevant multicast interface of MA5200G: igmp host-join group-address command. It can reduce time. Whether there is multicast users at or not, MA5200G will flood multicast traffic.
