Abstract
A device that includes a processor and a plurality of network interfaces. The plurality of network interfaces include a first network interface and secondary network interfaces. The first network interface is a currently enabled network interface for connecting the device to a service. The secondary network interfaces are currently inactive interfaces for connecting the device to the service. The processor is configured to send a heartbeat request to a heartbeat responder via the first network interface; determine whether a response is received from the heartbeat responder to the heartbeat request; and, in response to determining that the response to the heartbeat request was not received, deactivate the first network interface, and set a second network interface of the secondary network interfaces as the currently enabled network interface for connecting the device to the service.
