1.1 Register a Participant
...
Participant Registration is performed by a Participant when it starts up. It registers its ID and the ACM Element Types it supports with the ACM runtime.

1.2 Deregister a Participant
...
Participant Deregistration is performed by a Participant when it shuts down. It deregisters its ID and type with the ACM runtime.
The participant should already have cleared down all its ACM Element instances and set their states to UNINITIALIZED"Not In Service".

3 Supervise Participants
Participant Supervision is performed periodically between participants and the ACM runtime server to ensure that registered participants are available over time. Participants send a heartbeat message to the ACM runtime at a configured interval.
The heartbeat message contains updated status information for each AC Element Instance that has changed status since the last Heartbeat message sent by the participant

The ACM runtime regularly checks the heartbeat reports The ACM runtime regularly checks the heartbeat reports from participants and takes action of if participants time out. If a heartbeat message is not received for a participant in the Timeout Interval, the participant is marked as timed out and its ACM element instances are informed.
