This white paper provides an overview of IGMP and how it can support IPTV networks. IGMP is the protocol used to control multicast traffic delivery and allows clients to join and leave multicast groups, representing TV channels. When intermediate network devices are introduced, techniques like IGMP snooping, proxy routing, and query/report suppression are used to optimize multicast traffic delivery and IGMP message processing. These techniques aim to reduce bandwidth consumption and speed up channel change times.
