The following table describes the labels in this screen.
21.10 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 an xDSL port can use at a time. If each channel requires 4~5 Mbps
of download bandwidth, and the subscribers 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 xDSL connection.
To open this screen, click Advanced Application > IGMP > Counts Setup.
