Internet Group Management Protocol (IGMP)

DC-IGMP/MLD is a portable source code implementation of the Internet Group Management Protocol (IGMP) protocol designed explicitly to support the scalability, availability and functional requirements of OEMs building devices for next generation networks. It also supports the Multicast Listener Discovery (MLD) protocol, the IPv6 variant of IGMP.

DC-IGMP/MLD shares Metaswitch's multicast IP routing architecture.  It has comprehensive support for the relevant standards.
