Abstract: A power control system with a power management apparatus and a power monitoring control apparatus for each control segment. The power monitoring control apparatus is provided with: a contribution degree setting unit setting the degree of contribution of each control segment; a device control unit controlling the power consumption of each power using device connected; a priority control unit setting a priority for reducing the power of the power using device; and a device monitoring unit obtaining the priority of each power using device and transmitting the obtained priority to the power management apparatus. The power management apparatus is provided with an optimum control calculation unit determining a control command for controlling each power using device connected. The control command is determined based on: a target value of the total power consumption of all the control segments; the degree of contribution; and the priority of each power using device.

Abstract: A data transfer device calculates a compression performance value which represents a quantity of data that can be compressed per unit time and a transfer performance value which represents a quantity of data that can be transferred per unit time, and calculates, based on these values, a compression ratio which represents a ratio of data to be compressed and then transferred to total data to be transferred. The data transfer device extracts, from a storage unit which stores data, the data to be transferred, and then compresses part of the extracted data based on the compression ratio, and transfers the compressed data and remaining data to another device. The compression and transfer processes are performed in parallel.
