8.2.2 Example of a multicast application
The cameras for machine surveillance normally transmit their images to
monitor located in the machine room and in the monitoring room.
In a IP transmission, a camera sends its image data with a multicast address
over the network.
To prevent the many images from slowing down the entire network, the
Switch uses the GMRP to distribute multicast address information. As a
result, those images with a multicast address are only distributed to those
ports that are connected to the associated monitors for surveillance.
