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.

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.

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.

A time factor feature generation system includes: a use status grasping portion that extracts transition data showing variations in degree of use of a site from log data; a variation data generating portion that generates, based on the transition data, variation data expressing the variations in degree of use of the site as a group Y of values showing the degree of use of the site; a time factor data recording portion in which a plurality of time factors and time factor values of each of the plurality of time factors are recorded; a time factor extracting portion that generates groups Dof time factor values, each of which corresponds to a time factor extracted from among the plurality of time factors; and a time factor feature generating portionthat calculates coefficients asuch that a square of an error b has a minimum value in an equation in which the groups Dand the group Y are used as an explaining variable and an explained variable, respectively, thereby to generate data showing a time factor feature of a use status of the site. By this configuration, the time factor feature generation system generates data quantitatively showing a time factor feature of a use status of a site.
