Abstract: In an information processing apparatus, a transmitter forwards received data. A significance determination unit determines significance of the received data. Based on the significance of the received data, an operation mode selection unit selects which operation mode to apply. Power management information stored in a memory describes what power management is to be performed in each different operation mode. A control unit performs power management of the transmitter, with reference to the stored power management information corresponding to the selected operation mode.

Abstract: A model creation support system includes a model managing part that acquires and accumulates an identifier of a model, data indicating a phenomenon, data indicating a regression equation, and evaluation data from an information processing apparatus that predicts or analyzes the phenomenon, using a model represented by the regression equation, a factor value extracting part that generates and records factor value data indicating the degree to which the factor contributes to the model from the accumulated data, and a model proposing part that refers to the factor value data based on a request for supporting model creation and model condition data received from the information processing apparatus, thereby generating and outputting support data containing a factor capable of contributing to the model to the information processing apparatus. Thus, information on factors of the model can be accumulated and utilized for enhancement of the fitting degree of the model.

Abstract: In a routing apparatus, a state data reception unit identifies target paths involving a specified link and finds candidate paths which share their beginning and ending routing apparatuses with any one of the target paths and do not involve the specified link. The state data reception unit obtains state data of each candidate path from a management apparatus managing state data indicating states of routing apparatuses that forward traffic on the candidate paths. Based on the state data of each candidate path, a distribution path selection unit selects a distribution path that minimizes the increase in power consumption due to an expected change in the states of routing apparatuses. A distribution requesting unit transmits a distribution request to the beginning routing apparatus of a target path so as to distribute at least a part of the traffic on the target path to the selected distribution path.

Abstract: A first device, a second device, and a plurality of third devices are connected to one network. The second device holds attribute information of all the third devices. The first device sends a discovery request of a UPnP protocol. The discovery request includes a service type corresponding to the device-information providing service realized by the second device. When the second device receives the discovery request, it responds by sending back information indicative of the device-information providing service. When the first device receives the response from the second device, it understands the presence of the second device in the network, and sends an information demanding request for demanding attribute information of the third devices. In response, the second device sends the attribute information of the third devices to the first device.
