The SBC sends Device Watchdog Requests based on the configured Device Watchdog Timer value. Device Watchdog Timer is started once the transport connection towards a Diameter Peer is established. It is reset whenever any Diameter Message is received from the Diameter Peer. It can be a Device Watchdog Answer, some other Diameter Base Protocol Message, or any message from any of the Diameter Application (for example, Rx interface AAA messages).
