Abstract:
In a communication system, within a first subnetwork, a first image processing apparatus sets a first timeout time serving as a timeout time for communication within the first subnetwork and a second timeout time serving as a timeout time for communication between the first subnetwork and the second subnetwork, and notifies an image processing apparatus within the first subnetwork other than the first image processing apparatus of the first timeout time and the second timeout time and notifies a second image processing apparatus of the second timeout time.
Abstract:
An image forming apparatus which can reduce power consumption is provided. A service hub as an image forming apparatus has a print engine unit to form images, a MFP (Multifunction Peripheral) circuit which includes a main CPU (Central Processing Unit) to control the print engine unit, a network interface circuit to perform communication with external devices, and a server circuit which includes a main CPU to control the network interface circuit. The MFP circuit and the server circuit have a common IP address. The server circuit further includes an electric power control unit to control electric power supply to the MFP circuit and electric power supply to the server circuit being independent of each other.
Abstract:
An MFP sets an access condition for an external device with respect to a cloud box. The access condition is transmitted from the MFP to a relay device, and is registered in a memory of the relay device. When the relay device receives an access request made by the external device with respect to the MFP serving as an internal device, the relay device determines whether to permit or deny access to the MFP by comparing the access request with the access condition. When the access is permitted, the access request is transferred from the relay device to the MFP, whereas when the access is denied, the relay device notifies the external device of it.
Abstract:
An image processing device that communicates with a first server and a second server includes a main controller and a power controller. The main controller establishes a connection that enables communication with the first and second servers, establishes a periodic communication with the first and second servers to maintain the connection, manages a first time interval between the periodic communication with the first server, manages a second time interval between the periodic communication with the second server, and changes one or both of the first time interval and the second time interval. The power controller stops and starts power supply to the main controller.
Abstract:
An image processing system includes: an application server located in the Internet; an image processing apparatus located in a local network connected to the Internet via a firewall; a relay server configured to relay communication between the image processing apparatus and the application server, the relay server being located in the local network; and a connection mediation server configured to transmit, to the relay server, a request for a connection to the application server, the connection mediation server being located in the Internet, wherein the connection mediation server includes a connection request transmitting unit so as to have communication established between the image processing apparatus and the application server, the relay server includes: a communication establishing unit; a job transferring unit; a job identifying unit; and a communication terminating unit, and after the communication terminating unit terminates the communication, the communication establishing unit reestablishes the communication.
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.
Abstract:
An information system performing communication with a plurality of cloud servers is provided. The information system includes an information management portion configured to manage account information indicating accounts of a user of the information system, the accounts being set up for the cloud servers; an obtaining portion configured to, in response to operation of logging into the information system by the user, gain access to the cloud servers with the account information to obtain, from each of the cloud servers, usage information indicating use by the user; and a user interface portion configured to cause a display provided in a device operated by the user in order to log into the information system to display a list of the use of each of the cloud servers by the user.
Abstract:
An image processing device that is capable of executing a job by working together with a server, having: an application that establishes a connection that enables a communication with the server, and establishes periodic communications with the server at predetermined time intervals to maintain the connection; a periodic communication managing part that manages the periodic communication with the server by the application; and a power controller that includes a timer that measures a time elapsed after the application establishes the periodic communication, the power controller starting again a power supply to the application when the timer measures the time interval after the power supply to the application is stopped if a predetermined condition is met. The periodic communication managing part enables the application to establish the periodic communication with the server and resets the measured time before the power supply to the application is stopped by the power controller.
Abstract:
An information processing system has a portable information terminal and an information processing device that allow communication therebetween. The portable information terminal includes: a first application executing part for acquiring screen information indicating a screen with which a user makes remote operation from the information processing device and displaying the screen; and an informing part for sending access information as to a destination being accessed by a second application executing part to the information processing device when an application detecting part detects that both of the first and second application executing parts are running. The information processing device includes: a screen creating part for creating the screen based on the access information; and a transmitting part for sending the screen information created by the screen creating part to the portable information terminal. The first application executing part displays the screen based on the screen information received from the transmitting part.
Abstract:
A communication system includes a plurality of devices, a plurality of communication relay apparatuses, and a management server. If the management server that has received from a cloud server a request to access a specific device has no communication session with a specific communication relay apparatus that has control over the specific device, the management server transmits a tunnel connection request to a substitute apparatus (another communication relay apparatus different from the specific communication relay apparatus) via a communication session between the substitute apparatus and the management server. The substitute apparatus transfers the tunnel connection request to the specific communication relay apparatus and causes the specific communication relay apparatus to return from a power saving mode. The specific communication relay apparatus then establishes tunnel communication with the cloud server on the basis of the tunnel connection request to relay communication between the cloud server and the specific device.
