Unicoi Systems Releases Fusion IGMPv3

Generic Unicoi IconATLANTA, GEORGIA – October 24, 2006 – Unicoi Systems, a leading provider of real-time multimedia software and reference designs to embedded device developers and OEMs worldwide, today announced the release of its Fusion Internet Group Management Protocol Version 3 (IGMPv3).

The Internet Group Management Protocol is a communications protocol used to manage the membership of Internet Protocol multicast groups.  Multicasting can be used in a range of applications such as updating the address books of mobile computer users, distributing company newsletters to mailing lists, and broadcasting streaming media to multicast group members.

Fusion IGMP, a fully-integrated component of the Fusion TCP/IP networking stack, is part of Unicoi Systems’ middleware solution for multimedia devices.  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. 

Fusion IGMPv3 offers broad RFC support including:

  • RFC 3376 (IGMPv3)
  • RFC 2236 (IGMPv2)
  • RFC 3678  (Socket Interface Extensions for Multicast Source Filters)
  • RFC 1112 (Host Extensions for IP Multicasting)

With Fusion IGMPv3, multimedia device developers will also enjoy these benefits:

  • Support for “low leave latency”, which is a reduction in the time it takes for a multicast router to learn that there are no longer any members of a particular group present on an attached network
  • Support for “source filtering”, which is the ability for a system to report interest in listening to packets with a particular multicast address only from specific source addresses or from all sources except for specific source addresses
  • Interoperability with IGMPv1/v2
  • Support for IPv4/IPv6
  • Operating system and network stack independence
  • Small, efficient footprint and minimal CPU use
  • Written in 100% portable ANSI C
