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 to those ports only. It then propagates the service request up to any
neighboring multicast switch/router to ensure that it will continue to receive the
multicast service. This procedure is called multicast filtering.
