module interface

Module interface for IGMP modules.

An IGMP module sends notifications about multicast group memberships in hosts, and processes these notifications in multicast routers.

Currently there are 3 versions specified in RFC 1112 (IGMPv1), RFC 2236 (IGMPv2), and RFC 3376 (IGMPv3).

IGMP packets are transported by the IP layer connected to the ipIn/ipOut gates. Some multicast routing protocols (e.g. DVMRP) also communitacate with IGMP messages. They must be connected to the routerIn/routerOut gates, the IGMP module will pass up the unrecognized IGMP packets.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Implemented by

Name	Type	Description
Igmpv2	simple module	Imlementation of IGMPv2 protocol. Multicast routers use IGMP to learn which groups have members on each of their attached physical networks.
Igmpv3	simple module	(no description)

Used in compound modules

Name	Type	Description
Ipv4NetworkLayer	compound module	Network(1,2,3) layer of an IPv4 node.
