Multicast Filtering
Multicasting is used to support real-time
applications such as videoconferencing or
streaming audio. A multicast server does not have
to establish a separate connection with each
client. It merely broadcasts its service to the
network, and any hosts that want to receive the
multicast register with their local multicast switch/
router. Although this approach reduces the
network overhead required by a multicast server,
the broadcast traffic must be carefully pruned at
every multicast switch/router it passes through to
ensure that traffic is only passed on to the hosts
which subscribed to this service.
This switch uses IGMP (Internet Group
Management Protocol) to query for any attached
hosts that want to receive a specific multicast
service. It identifies the ports containing hosts
requesting to join the service and sends data out
