Multicasting
GlobeSurfer 3G provides support for IGMP multicasting, which allows hosts
connected to a network to be updated whenever an important change occurs
in the network. A multicast is simply a message that is sent simultaneously to
a pre-defined group of recipients. When you join a multicast group you will
receive all messages addressed to the group, much like what happens when an
e-mail message is sent to a mailing list.
IGMP multicasting enables UPnP capabilities over wireless networks and may
also be useful when connected to the Internet through a router. When an appli-
cation running on a computer in the local network sends out a request to join
a multicast group GlobeSurfer 3G intercepts and processes the request.
