Definitions
- the invention relates to a method for checking the operational readiness of a communication link between a gateway and a central cloud service.
- the invention also relates to a gateway set up to carry out the method.
- Gateways are also used to connect networks (e.g. networks at corresponding customers) with a cloud infrastructure. This allows network nodes, for example, to access services from cloud applications.
- a message is periodically sent over the connection to check the operational readiness of the communication connection (heartbeat function).
- MQTT Message Queuing Telemetry Transport
- a gateway comprising a communication component which is set up for a data communication with a central cloud service, a check message (heartbeat) being able to be sent from the communication component to the central cloud service to check the operational readiness of the communication connection between the gateway and the central cloud service, the check message being useful information ( payload) from further components of the gateway. If useful information (payload) from other components of the gateway is available or available, this useful information is transmitted together with the verification message.
- the verification message advantageously has a corresponding data format or a data protocol in order to transmit the useful information.
- the gateway is advantageously an edge device (edge device computer, edge device, edge gateway).
- the gateway can also be a correspondingly set up and configured "general purpose" computer with processor, memory, input / output means, communication means.
- the gateway according to the invention enables one adaptive heartbeat mechanism for cloud applications that can be scaled according to communication requirements
- the gateway is advantageously a node or a device in a network, e.g. a network of devices (e.g. IoT devices) for building automation.
- the gateway advantageously provides a communication connection (corresponding hardware and software ) of the network to the Internet or to a cloud infrastructure (e.g. for retrieval or Activation of cloud services).
- a first advantageous embodiment of the invention is that the data communication to the central cloud service is established by the communication component of the gateway becomes.

- the communication connection is set up physically from the gateway.
- the communication link is physically unidirectional, but logically bidirectional.
- Verification messages and the associated user data can be buffered, compressed or encrypted in the cloud, but also in the gateway.
- the useful information is an event and / or a change in value and / or a change in status in the gateway.
- the useful information can therefore be of different data types and values.
- a further advantageous embodiment of the invention is that the useful information is provided by a corresponding application interface (API) or programming interface for cloud-based applications. Services and applications in the cloud can access the useful information through the application interface (API) or programming interface and use this to provide their services and applications.

- a further advantageous embodiment of the invention is that the communication component is set up to receive a confirmation from the central cloud service in response to a sent verification message. With the confirmation, the gateway recognizes that the communication connection is ready for operation.
- the confirmation includes usage formation (payload) of cloud services or cloud applications for the gateway or for components of the gateway.
- the communication component is set up to send the check message (heartbeat) periodically to the central cloud service at definable time intervals.
- the interval for checking the operational readiness of the communication connection can thus be changed.
- the interval of checking the operational readiness of the communication link can advantageously be flexibly adapted to the existing framework conditions or requirements.
- the time intervals between the verification message (heartbeat) can be set or changed by the gateway or by applications on the gateway.
- the time intervals for the verification message (heartbeat) can, however, also be set or changed by cloud services, advantageously depending on the requirements (e.g. with regard to the required reliability of the communication connection).
- a further advantageous embodiment of the invention is that the communication component is set up to send the check message (heartbeat) when requested by the central cloud service.

This software environment contains all parts for the operation of an application: operating system, code, runtime, system tools, libraries and Settings. This software environment completely isolates the software application from the environment and thus guarantees a high level of security with regard to insulation lation of this process.
