Data processing system, management device with first reception port and second reception port, relay device, device to be managed, data processing method, and data processing program

A management device comprising a first hardware processor that:

• registers a set of a relay device and a device to be managed;
• in response to registration of the set of the relay device and the device to be managed, prepares a first reception port via the relay device and a second reception port not via the relay device as reception windows for data generated by the device to be managed, the first reception port and the second reception port being configured on the management device;
• controls the relay device to cause the device to be managed to set the second reception port;
• and
• in response to reception of data generated by the device to be managed via the first reception port or the second reception port, processes the data.

A relay device that relays between a device to be managed and a management device that processes data generated by the device to be managed, the relay device comprising

• a second hardware processor that:
• in response to reception of data generated by the device to be managed, transmits the data or data obtained by processing the data to a first reception port prepared by the management device for a set of the relay device and the device to be managed;
• and
• causes the device to be managed to set a second reception port prepared by the management device for a set of the relay device and the device to be managed, the first reception port and the second reception port are configured on the management device.

A device to be managed comprising a third hardware processor that:

• registers a relay device as a first transmission destination;
• sets a first reception port prepared by a management device for the first transmission destination;
• in response to an instruction from the relay device to set a second reception port prepared by the management device for a set of the relay device and the device to be managed, registers the second reception port as a second transmission destination, the second reception port and the first reception port being configured on the management device;
• generates data;
• transmits the generated data to the first transmission destination;
• and
• transmits the data to the second transmission destination when transmission of the data to the first transmission destination fails.

A data processing method for causing a management device to execute:

• registering a set of a relay device and a device to be managed;
• in response to registration of the set of the relay device and the device to be managed, preparing a first reception port via the relay device and a second reception port not via the relay device as reception windows for data generated by the device to be managed, and wherein the first reception port and the second reception port are configured on the management device;
• controlling the relay device to cause the device to be managed to set the second reception port;
• and,
• in response to reception of data generated by the device to be managed via the first reception port or the second reception port, processing the data.

A data processing method for causing a device to be managed to execute:

• registering a relay device as a first transmission destination;
• setting a first reception port prepared by a management device for the first transmission destination;
• in response to an instruction from the relay device to set a second reception port prepared by the management device for a set of the relay device and the device to be managed, registering the second reception port as a second transmission destination, the first reception port and the second reception port being configured on the management device;
• generating data;
• transmitting the generated data to the first transmission destination;
• and
• transmitting the data to the second transmission destination when transmission of the data to the first transmission destination fails.

A non-transitory recording medium storing a computer readable data processing program causing a computer to perform:

• registering a set of a relay device and a device to be managed;
• in response to registration of the set of the relay device and the device to be managed, preparing a first reception port via the relay device and a second reception port not via the relay device as reception windows for data generated by the device to be managed by a management device, the first reception port and the second reception port being configured on the management device;
• controlling the relay device to cause the device to be managed to set the second reception port;
• and,
• in response to reception of data generated by the device to be managed via the first reception port or the second reception port, processing the data.
