If the controller is normally connected to the Internet via Ethernet or Wi-Fi, and GPRS is to be used only in case of a main channel failure, this mode of operation is called failover. It usually works like this:
- Work is organized through the main channel.
- The availability of Internet access through the main channel is constantly checked.
- In case of problems, a backup connection is started and the default gateway settings are changed.
- The main connection is constantly checked, and if the internet access is restored through it, the system returns to work via it, changing the default gateway.
