8.2.2 Example of a Multicast Application
The cameras for monitoring machines normally transmit their images to
monitors located in the machine room and to the control room.
In an IP transmission, a camera sends its image data with a Multicast
address via the network.
To prevent all the video 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.
