3-9-6. RADIUS IGMP
Function name:
RADIUS IGMP
Function description:
The RADIUS IGMP function allows to some multicast applications, such as
IPTV and Internet Radio, may be of minimal interest to law enforcement
agencies, other multicast traffic may contain information important to an
investigation. The problem of not intercepting incoming multicast traffic affects
not only targets directly intercepted by IP address, but also targets intercepted
by login name, calling line identity, MAC address, and similar identities used
by such protocols as RADIUS and DHCP for authentication and dynamic IP
allocation.
A lawful interception solution that analyzes RADIUS and DHCP for target IP
addresses will likely fail to intercept incoming multicast traffic to the target.
