5.8.2.10 Multicast
The multicast interface is shown as in Figure 5-31 Multicast is a transmission mode of data
packet. When there is multiple-host to receive the same data packet, multiple-cast is the
best option to reduce the broad width and the CPU load. The source host can just send out
one data to transit. This function also depends on the relationship of the group member and
group of the outer.

5.8.2.11 Alarm Center (optional)
The alarm center interface is shown as below. See Figure 5-32. This interface is reserved for
you to develop. System can upload alarm signal to the alarm center when local alarm occurs.
Before you use alarm center, set server IP, port and etc. When an alarm occurs, system can
send out data as the protocol defined, so the client-end can get the data.
