Internet Group Management Protocol

(protocol)
(IGMP) An extension to the Internet Protocol, used by IP hosts to report their host group memberships to immediately-neighbouring multicast routers.

See also MBONE.

Version 1 of IGMP is defined in Appendix 1 of RFC 1112.

Version 2 is proposed in RFC 2236.

IGMPv3 support, which enables video technicians to rapidly access any program for testing by directly connecting them to a media switch -- GigE and QAM Channel Scanning to let users automate the process of monitoring the performance of video against MPEG compliances -- SNMP for real-time alarming for heightened awareness of the condition of video quality -- MS-RTP to allow users to recognize, parse and display MPEG streams embedded in a Microsoft RTP1.
It also supports VoIP with SIP and H248 and supports IPTV with IGMPv3 for fast TV channel change.
Full stateful IGMP multicast support: tracks and allows/deny multicast traffic, with support for IGMPv1, IGMPv2, and IGMPv3
The switches incorporate device driver software offering an easy-to- use API supporting advanced access control, and various protocol modules including IGMPv3 for IP video applications.
In particular, the addition of IGMPv3 support makes Raptor Networks much more attractive in digital cable transport and emerging applications such as IPTV.
The addition of IGMPv3, MLDv2, and DHCPv4 support also extends IxANVL's coverage of key protocols commonly deployed by Service Providers at the customer edge of their networks to control access and configuration of video and data services.
Unicoi's middleware solution, which simplifies the design process for multimedia devices such as digital set-top boxes and IP video phones, includes an embedded media player and a complete line of fully integrated Fusion multimedia software, including IGMPv3, RTP, RTCP, RTSP, SIP and the WebPilot embedded web browser.
4 also supports VoIP with SIP and H248, supporting IPTV with IGMPv3 for fast TV channel change.
The latest dual Gigabit Ethernet modules support IGMPv3 to enable diverse routing where multicast sessions are in use, SMPTE 2022-2 (ProMPEG) FEC to recover dropped packets, and configurable buffers to enable low delay content distribution.
Both IGMPv3 and URD enable a user to easily join a multicast group and receive content transmitted to that group, while providing the network administrator with enhanced capabilities to manage multicast streams.
