HITRON CGN USER’S GUIDE
IGMP Snooping
Use this field to turn Internet Group Management
Protocol (IGMP) snooping on or off.
IGMP is used to manage multicast groups. In multicast
groups, data is transmitted to numerous IP addresses
simultaneously. This is the most efficient method of
providing the same data to many different recipients at
the same time, since each data packet needs to be sent
only once. Multicast groups are often used for Internet
TV and real-time streaming applications such as online
gaming.
IGMP snooping allows the CGN to “snoop” or listen in on
IGMP traffic, and to determine which computers on the
LAN belong to which IGMP groups. By keeping lists of
which computers belong to IGMP groups, the CGN can
send the IGMP data to only those computers that have
requested it, and can refrain from sending unsolicited
multicast data. This can improve your connection to
wireless clients.
