Abstract:
A gateway apparatus connected to an image processing apparatus in a communicable manner and connected to an external apparatus via a network, and performing communication control between the image processing apparatus and the external apparatus, includes: a main CPU; a sub CPU; a first detecting unit configured to detect a state of a primary power supply; a second detecting unit configured to detect a state of a secondary power supply; a generating unit configured to generate a transfer instruction message; an acquiring unit configured to acquire information about a change in a state of the gateway apparatus or an apparatus located in the vicinity of the gateway apparatus; an updating unit configured to repeatedly perform updating of the transfer instruction message; and a transmitting unit configured to transmit the last-generated or last-updated transfer instruction message to an external alternate apparatus.
Abstract:
A management server disposed outside a firewall and supporting connection of communications between a control target device disposed inside the firewall and a cloud server disposed outside the firewall, includes a server-side session establishing portion to, based on a request from a relay device disposed inside the firewall, establish a session with the relay device, a device information acquiring portion to acquire device information about the control target device from the relay device via the established session, and an update determining portion to, in response to reception of a request of connecting to the control target device from the cloud server, determine whether to update the device information. The device information acquiring portion includes an upon-session-establishment acquiring portion to acquire the device information when a session with the relay device is established, and an upon-session-request acquiring portion to acquire the device information after updating the device information is determined.
