For multicast type traffic the traffic pattern will look more like the graph above. Here the bitrate is much
more steady even for short intervals. The network never experiences near line-speed bursting since each
stream is bitrate controlled by the sender.

6.8.1 Ethernet — FSM
Full Service Monitoring (FSM) allows easy validation of any server reachable by the probe via Ethernet.
The servers may be probed by either sending an ICMP Echo Request packet (also known as Ping) or
performing an HTTP Get request.
Up to 10 services may be defined and each service will be checked at regular intervals. Any errors will
be logged. An error is defined as no reply within 5 seconds for the Ping option or no, or incorrect, reply
within 5 seconds for the HTTP option. If there are more consecutive errors than a fails threshold value an
alarm will be raised.
