ASAI Maintenance Capabilities

Heartbeat

This capability enables the adjunct or the ECS to send an application-to-application message and receive a response in order to determine the sanity of the application on the remote endpoint.

Information Flow

The sender expects a response to its request.

The ECS responds to the Heartbeat within 60 seconds.

The ECS sends the Heartbeat message over each established signaling link to an adjunct every two minutes. The adjunct is required to respond to the ECS within ten seconds. Failure to respond to three consecutive heartbeats results in the ECS bringing the link down and attempting to bring it back up again.
