7.2.2 Example of a Multicast application

The cameras for monitoring machines normally transmit their images to mon-
itors located in the machine room and to the monitoring room. In an IP trans-
mission, a camera sends its image data with a Multicast address via the
network.
To prevent all the image data from slowing down the entire network, the
device uses the GMRP to distribute the Multicast address information. As a
result, the image data with a Multicast address is only distributed to those
ports that are connected to the associated monitors for surveillance.
