摘要:
A server acquires the total number of pages printed per hour and the number of pages printed per hour by each user on each printer in a network printing system in order to find printers whose hourly number of printed pages exceeds a load limit. The server also looks for printers having few printed pages per hour that do not exceed the load limit and issues a notification advising the user who is printing the largest volume on a printer exceeding the load limit to switch to a printer that prints few pages. Accordingly, a high concentration of printing found on a few printers can be moderated, reducing user wait time and excessive printer load.

A device management system that can easily manage devices on a network existing beyond a router. In the device management system, firstly, a management device transmits a packet to a probe device beyond a router. Then, the probe device broadcasts onto a network. Then, the device on the network transmits, by return, a reply-packet to the probe device. Then, the probe device determines whether the reply-packet is one received from the device that is to be managed, and transmits to the management device only the reply packet received from the device that is to be managed.

A communication system includes an information processing device and a management device including a challenge input device, an encryption device, and a combination data output device. The challenge input device inputs challenge data output by the information processing device. The encryption device creates combination data including the challenge data and the predetermined data, and encrypts the combination data in units of blocks. The encryption device creates the combination data such that at least one block of the combination data includes both at least a part of the challenge data and at least a part of the predetermined data. The combination data output device outputs the combination data encrypted by the encryption device to the information processing device. The information processing device is provided with a challenge output device, a challenge storage, a combination data input device, a decryption device, and a data utilizing device.

A communication system is provided with an information processing device, and a management device capable of updating old data stored in the information processing device by outputting new data to the information processing device. The management device is provided with an old data input device that inputs the old data, a first new data input device that inputs the new data, an encryption device that encrypts the new data by utilizing the old data as a key, and a new data output device that outputs the new data encrypted by the encryption device to the information processing device. The information processing device is provided with an old data storage that stores the old data, a second new data input device that inputs the encrypted new data output by the management device, a decryption device that decrypts the encrypted new data by utilizing the old data as a key, and an updating device that updates the old data stored in the old data storage to the new data decrypted by the decryption device.
摘要:
An information-processing apparatus which is capable of transmitting device identifiers of devices connected with LANs to terminals without using a broadcast command is provided. A server is connected with a World Area Network. A managing terminal and printers are connected with a LAN. The server receives a device identifier of the printer connected with any one of the LANs. The server receives an inquiry for a device identifier from a terminal connected with any one of the LANs. The server stores appended information, which is appended to the device identifier while the device identifier is transferred to the server, in a manner that the appended information is associated with the device identifier. The server transmits to the terminal the device identifier whose appended information as stored in a storage coincides with the appended information that is appended to the inquiry while the inquiry is transferred to the server. The managing terminal can obtain the device identifier of the printer connected with the same LAN as the managing terminal itself by transmitting the inquiry to the server.
摘要:
A network terminal device is configured to include a plurality of network applications that generate process instructions to cause devices on a network to execute processes, a storage unit that stores common network configuration information of the plurality of network applications, and a network terminal device where each of the plurality of network applications is capable of reading out the common network configuration information from the storage unit and reflecting the same in its own network configuration. Each application may transmit the process instructions to the device on the network based on the network configuration.
