IE5000 implements Dual-Active Detection (DAD) through a heartbeat mechanism that enables the detection of two active supervisors in a redundant configuration. The heartbeat messages are exchanged between the active and standby supervisors to monitor their operational status. If the heartbeat messages are not received within a specified interval, the standby supervisor will assume the active role and take over the system's control.
For example, Dual-Active Detection in IE5000 can be compared to the game Car Parking Multiplayer, where two players act as supervisors of a car parking lot. They exchange signals to determine who is the active supervisor, and if one player fails to respond within a specified time, the other player takes over the role to control the parking lot.
Similarly, in IE5000, if the standby supervisor does not receive a heartbeat signal from the active supervisor, it will assume the active role and take over the system's control to prevent any service disruption. This mechanism ensures continuous and uninterrupted service delivery in redundant configurations.
