An increase in communication traffic at the time of transmission of commands of controlling power consumption of individual buildings can be suppressed so as to be low. A wide area management system includes a wide area management device that includes a database that stores a command table and a transmission unit that transmits a control command to each uppermost-level building management device and building management devices, each of which includes a database that stores a management table and a building-associated correspondence table, a transfer unit where, in a case where a reception unit receives the control command, specifies lower-level building management devices by referring to the management table and transfers the received control command to each of the specified building management devices, an event program extraction unit that extracts an event program corresponding to the control command from a building-associated correspondence table, and an event program execution unit that executes the extracted event program to control power consumption of the buildings.

Managing energy consumption of a building in an interconnected wide area management system

Even when there are a lot of buildings as a management target, a power consumption of each building can be appropriately managed. A broad area management systemis provided with a broad area management apparatusin which a control command reception unitreceiving a selection of a control command of a power consumption from an operation terminal of an administrator and a transmission unittransmitting received one control command to a plurality of building management apparatusesare included, and the building management apparatusin which an event program execution unitstoring an event program in association with the control command, a reception unitextracting the event program corresponding to the control command from the event program execution unitin a case where the control command is received from the broad area management apparatus, an event program extraction unitcontrolling the power consumption of each facilityby executing the extracted event program.

A mobile IPv6 dual-stack node engages in IPv6 communication while roaming within an IPv4-only network, for example using ISATAP. First, the node determines that it has moved Bnd obtains a new IPv4 address. After determining that the visited network contains no IPv6-enabled components, the node uses an IPv6 connect agent to engage in IPv6 communication. The node configures its care-of address using the IPv6 connect agent's routing information and the node's newly-obtained IPv4 address. In one embodiment, the node and the connect agent optimize the handoff when the nodes has moved but still uses the same connect agent. The node sends a binding updates to the connect agents comprising the node's old care-of address and the node's new care-of address. When the connect agent receives a packet destined for the node's previous care-of address, it forwards the packet to the node's currents care-of address, thereby reducing packet loss.
