Control device, image output apparatus, image output system, non-transitory computer readable medium, and control method

A control device comprising:

• a first acquisition unit that acquires a first notification reservation request which requests a notification reservation of an event and includes first identification information for identifying a notification destination of the event;
• a second acquisition unit that acquires a second notification reservation request which requests a notification reservation of an event and includes second identification information for identifying a notification destination of the event;
• a first controller that performs a control such that information regarding the notification reservation of the event requested by the second notification reservation request is stored in a memory according to a difference between the first identification information and the second identification information;
• and
• a second controller that performs a control such that information regarding the notification reservation of the event requested by the first notification reservation request is stored in the memory,
• wherein, when the difference between the first identification information and the second identification information satisfies a preset condition, the first controller performs a control such that the information regarding the notification reservation of the event requested by the first notification reservation request, stored in the memory, is deleted, and performs a control such that the information regarding the notification reservation of the event requested by the second notification reservation request is stored in the memory,
• the control device further comprising a notification unit that sends a notification of the event to a notification destination which is identified by the second identification information on the basis of the information regarding the notification reservation of the event requested by the second notification reservation request, stored in the memory,
• wherein, when the notification by the notification unit fails, the first controller performs a control such that the notification unit does not send the notification on the basis of the information regarding the notification reservation of the event requested by the second notification reservation request, stored in the memory,
• the control device further comprising a third acquisition unit that acquires an image output request which requests an image output apparatus outputting images to output images and includes the second identification information,
• wherein, when the information regarding the notification reservation of the event requested by the second notification reservation request is stored in the memory, the first controller performs a control such that information indicating that the reservation is invalid is stored so as to be correlated with the information regarding the notification reservation,
• wherein, when the image output request is acquired by the acquisition unit, the first controller performs a control such that the information indicating that the reservation is invalid is updated to information indicating that the reservation is valid in the memory, and
• wherein, when the info nation regarding the notification reservation of the event requested by the second notification reservation request, stored in the memory, is correlated not with the information indicating that the reservation is invalid but with the information indicating that the information is valid, the notification unit sends a notification of the event to a notification destination identified by the second identification information on the basis of the information regarding the notification reservation of the event.

A control device comprising:

• a second acquisition unit that acquires a second notification reservation request which requests a notification reservation of an event and includes second identification information for identifying a notification destination of the event;
• a first controller that performs a control such that information regarding the notification reservation of the event requested by the second notification reservation request is stored in a memory according to a difference between the first identification information and the second identification information;
• and
• a second controller that performs a control such that information regarding the notification reservation of the event requested by the first notification reservation request is stored in the memory,
• wherein the first identification information includes a first Internet Protocol (IP) address and a first Media Access Control (MAC) address,
• wherein the second identification information includes a second IP address and a second MAC address,
• wherein, when a difference between the first IP address and the second IP address satisfies a preset condition, and a difference between the first MAC address and the second MAC address does not satisfy a preset condition, the first controller performs a control such that the information regarding the notification reservation of the event requested by the first notification reservation request, stored in the memory, is deleted, and performs a control such that the information regarding the notification reservation of the event requested by the second notification reservation request is stored in the memory, and
• wherein, when the difference between the first MAC address and the second MAC address satisfies the preset condition, the first controller performs a control such that the information regarding the notification reservation of the event requested by the first notification reservation request, stored in the memory, is updated to the information regarding the notification reservation of the event requested by the second notification reservation request,
• the control device further comprising a notification unit that sends a notification of the event to a notification destination which is identified by the second identification information on the basis of the information regarding the notification reservation of the event requested by the second notification reservation request, stored in the memory,
• wherein, when the notification by the notification unit fails, the first controller performs a control such that the notification unit does not send the notification on the basis of the information regarding the notification reservation of the event requested by the second notification reservation request, stored in the memory,
• the control device further comprising a third acquisition unit that acquires an image output request which requests an image output apparatus outputting images to output images and includes the second identification information,
• wherein, when the information regarding the notification reservation of the event requested by the second notification reservation request is stored in the memory, the first controller performs a control such that information indicating that the reservation is invalid is stored so as to be correlated with the information regarding the notification reservation,
• wherein, when the image output request is acquired by the acquisition unit, the first controller performs a control such that the information indicating that the reservation is invalid is updated to information indicating that the reservation is valid in the memory, and
• wherein, when the information regarding the notification reservation of the event requested by the second notification reservation request, stored in the memory, is correlated not with the information indicating that the reservation is invalid but with the information indicating that the information is valid, the notification unit sends a notification of the event to a notification destination identified by the second identification information on the basis of the information regarding the notification reservation of the event.
