Overview :
The Aricent IGMP software is a portable implementation of the IGMP (Internet Group Management Protocol) specification version 3 [RFC 3376]. IGMP is the protocol used by IPv4 systems to report their IP multicast group memberships to neighboring multicast routers. Version 3 of IGMP adds support for "source filtering", that is, the ability for a system to report interest in receiving packets *only* from specific source addresses, or from *all but* specific source addresses, sent to a particular multicast address. This information is used by multicast routing protocols to avoid delivering multicast packets from specific sources to networks where there are no interested receivers. Aricent IGMP implements the IGMP-router functionality.

Features:
- Implements IGMP version 3 router functionality.
- Provides backward compatibility with IGMP version 1 and IGMP version 2.
- Provides well-defined APIs for interaction with the multicast routing protocols.
- Implements source filtering, and conforms to the standard for maintaining the group membership state integrity.
- Supports fast leave management per interface.
- Supports Static-Group Membership.
- Supports IP router alert option in the IP-header.
- Provides complete CLI support.
- Provides complete support for SNMP-based management by implementing the MIBs in draft-ietf-magma-rfc2933-update-00.txt.
- Provides support for seamless integration with Aricent PIM, Aricent SNMP and Aricent IP.
- Integrates easily in a system that supports BSD compliant socket (e.g. Linux, FreeBSD) with the usage of standard socket calls for packet transmission and reception.
- Conforms to Future Software Architecture for Portability (FSAP2), thus ensuring highly portable code that uses flexible buffer and timer management libraries.
Benefits:
Aricent IGMP reduces the time to market for OEMs and VARs who wish to incorporate the IGMP functionality into their switching/routing devices.
