The Internet Group Management Protocol with Access Control (IGMP-AC) has been designed for incorporating AAA protocol functionality in the existing IP multicast model. It will enforce authentication and authorization of an end user or receiver before joining or leaving a secured multicast group. To add AAA functionality, an access router or one-hop router of the receiver will act as a network access server (NAS).
IGMP-AC is an extended version of Internet Group Management Protocol. It provides a generic client-server authentication protocol, where the receiver or end user will act as a client, the AAA server will act as a server and the access router (one-hop router of the receiver) will perform the forwarding task. Thus, any suitable authentication protocol (e.g., Extensible Authentication Protocol (EAP)) having client-server entities can be encapsulated over the IGMP-AC architecture. The IGMP-AC will not disrupt the usual function of the IGMPv3 (to be used for classical multicast group), and the access control mechanism of IGMP-AC will take place to join/leave a secured or restricted multicast group only.

“If the Russians have gone too far in subjecting the child and his peer group to conformity to a single set of values imposed by the adult society, perhaps we have reached the point of diminishing returns in allowing excessive autonomy and in failing to utilize the constructive potential of the peer group in developing social responsibility and consideration for others.”
—Urie Bronfenbrenner (b. 1917)
“The care of a house, the conduct of a home, the management of children, the instruction and government of servants, are as deserving of scientific treatment and scientific professors and lectureships as are the care of farms, the management of manure and crops, and the raising and care of stock.”
—Catherine E. Beecher (1800–1878)
“Lesbian existence comprises both the breaking of a taboo and the rejection of a compulsory way of life. It is also a direct or indirect attack on the male right of access to women.”
—Adrienne Rich (b. 1929)
“Only one thing is certain: if pot is legalized, it won’t be for our benefit but for the authorities’. To have it legalized will also be to lose control of it.”
