20.7 IGMP Count Screen

Use this screen to limit the number of IGMP groups a subscriber on a port can join. This
allows you to control the distribution of multicast services (such as content information
distribution) based on service plans and types of subscription.
IGMP count is useful for ensuring the service quality of high bandwidth services like video or
Internet Protocol television (IPTV). IGMP count can limit how many channels (IGMP groups)
the subscriber connected to a DSL port can use at a time. If each channel requires 4~5 Mbps of
download bandwidth, and the subscriber's connection supports 11 Mbps, you can use IGMP
count to limit the subscriber to using just 2 channels at a time. This also effectively limits the
subscriber to using only two IPTVs with the DSL connection.
To open this screen, click Advanced Application, IGMP, Count Setup.
