Any-Source Multicast

Any-Source Multicast allows a host computer to map IPs and then sends IPs to a number of groups via IP address. This method of multicasting allows hosts to transmit to/from groups without any restriction on the location of end-user computers^[1] by allowing any receiving host group computer to become a transmission source.^[2] Bandwidth usage is nominal allowing Video Conferencing to be used extensively.^[3] However, this type of multicast is vulnerable in that is allows for unauthorized traffic and denial-of-service attacks.^[2]

Commonly, Any-Source Multicast is used in IGMP version 2; however, it can also be used in PIM-SM, MSDP, and MBGP. ASM utilizes IPv4 in

association with the previously stated protocols; in addition, MLDv1 protocol is used for IPv6 addresses.^[1]

Benefits

Scalability for large tasks ^[4]
The reduction of group management ^[4]
Ability to use existing technologies ^[4]
