A reconfigurable integrated circuit device which converts an arbitrary calculation state dynamically, based on configuration data, includes a plurality of processor elements, each of which has an input terminal, an output terminal, a plurality of arithmetic units which are provided in parallel and each of which performs calculation processing in synchronous with a clock signal, and an intra-processor network which connects them in an arbitrary state; and an inter-processor network which connects between processor elements in an arbitrary state. Based on configuration data, the intra-processor network is reconfigurable to a desired connection state, and further, based on the configuration data, the inter-processor network is reconfigurable to a desired connection state.

A radio network can select a route of minimum path loss among entire relay routes and can set the relay route so as to satisfactorily resist interference. The radio network has a core node connected to a wired network, relay nodes each relaying at least one of a down-link data packet transmitted from the core node and an up-link data packet directed toward the core node, and a terminal station capable of transmission and reception of data packets with both the core node and the relay node. The relay node has total path loss optimized to be minimum between relay nodes included in a relay route of the data packet or between the relay node and the core node or both.

A processing element includes a shift register including n stages of registers mutually connected in series. Data held among the n stages of registers is rotated in synchronization with a clock signal. A number-of-stages determining circuit determines the number of stages to be used among the n stages of registers. An output terminal of the register in the last stage connects to an input terminal of the register in the first stage.

In case a fault has occurred in a volume, it was so far difficult to correctly notify a fault by using a host computer which can access the volumes managed by a management computer that integrally manages a plurality of devices constituting a network. The management program of the invention is executed by the management computer connected to computers and to a plurality of storage devices for managing the volumes connected to the computers through a SAN (storage area network). The management program executes a procedure for receiving a notice of fault in the volume from the storage devices, a procedure for receiving volume access control information from a plurality of storage devices for specifying the computers that can access the volumes, and a procedure for notifying the fault in the volume to the computers that are permitted to access the volumes based on the volume access control information.

To provide a data transmission method and an apparatus thereof in a relay transmission type radio network capable of selecting an appropriate down-link relay route according to a location of a terminal station. A first relay node having received an up-link ACK packet transmitted by the terminal station transmits to an second relay node the up-link ACK packet including a source terminal station ID and a relay source node ID representing its own node ID. The second relay node having received the up-link ACK packet registers information on a pair of the source terminal station ID and the relay source node ID with a relay node list, and selects an appropriate route of a down-link packet addressed to the terminal station by using the information registered with the relay node list.

A computer management system attains, through one line, the uniform and steady system management through an agent such as monitoring of fault and power control in a computer connected by LAN as well as a public line, and system management for an off-state of the computer or abnormal operation state of the computer such as remote power control and notice and diagnosis of critical fault by the direct connection with a service processor through the line. The system includes an agent connected to a computer to be managed for executing instructions on the computer to be managed, a service processor board having a processor independent from the computer to be managed for monitoring fault in the computer to be managed and controlling power of the computer to be managed, a manager for executing instructions on a management computer and conducting controls such as fault monitoring and power control through the agent over a network including a public line, and a service processor manager directly connected to the service processor for conducting remote power-on and receiving and diagnosing critical fault. The service processor and the service processor manager are provided with switching circuits for switching an asynchronous interface for remotely connecting to the computer to be managed and an asynchronous interface for directly connecting to a local processor of the service processor.

The invention provides a method of selecting a base station according to which optimal quality can be achieved in the communication between a mobile station and a communication destination by efficiently using resources of the entire wireless network, as well as a mobile station and a base station. The base station selection method selects one from a plurality of base stations connected to the relay server, for a connection with the mobile station. In the method, each base station retains abase station routing cost which is a cost for the path connecting the base station to the communication network. And the mobile station measures a toward-base station routing cost for the path between itself and each base station, calculates a total routing cost for each base station by adding the base station routing cost and the toward-base station routing cost, and selects a base station associated with a minimal total routing cost when establishing a relay connection with the communication network.
