In a name resolution device for managing a name of each node connected to a network and an address for identifying each node, a node information containing a name of a node, a network identification information, a prefix indicating a position on the network, and an interface identification information of a node is stored for each node, and the node information of other nodes connected to the network is collected through the network. Then, the stored node information is updated according to the collected node information of the other nodes, by updating the stored prefix by using the interface identification information contained in the collected node information as a key.

A communication control apparatus includes: a storage device, an input device, an output device, a communication control apparatus, a main storage device and a processor (CPU). The CPU includes an address segmentation unit, a weight detector and a connection controller. The address segmentation unit splits a received packet, the weight detector detects the weight of each segment of the packet, and the connection controller employs the weight to provide connection control for the packet.

A domain name system inquiry (DNS) apparatus and a domain name system inquiry method which are capable of obtaining a desired response at high speed even when there are a plurality of trees of domain name systems are provided. For this purpose, location information received by a current location information receiving device for receiving location information of the apparatus itself on a connected network is stored. Then, server information received by a server information receiving device for receiving server information about a DNS server to which an inquiry can be made is stored. Then, an inquiry request is transferred to at least one DNS server determined based on the location information and the server information, and based on a response therefor, the server information is rewritten, and a response result corresponding to the inquiry request is selected.

A printing system comprises a printer in communication with a host computer through a bidirectional data transfer connection. A first processing time predicting section is capable of predicting first data processing time taken for the host computer to generate bit image data from print data. A second processing time predicting section is capable of predicting second data processing time taken for the printer to generate bit image data from print data. A transfer time predicting section is capable of predicting data transfer time taken for the data transfer connector to transfer data. A distribution controlling section determines distribution of data processing needed to generate bit image data from print data based on combination of the first and second data processing times predicted and the transfer time predicted to provide shortest time data processing distribution plan.

A relay device is provided that includes a reception unit and a transmission unit. The reception unit receives a startup packet including a magic packet, a MAC address of controllable equipment, and a first ID for starting up the controllable equipment. The transmission unit transmits a first electric signal indicating the first ID to all link-downed Ethernet ports.

When handover is performed from a first network to a second network, a home agent transmits a reply request message to a terminal through the first network after new configuration of a tunnel for transmitting and receiving a packet through the second network. If the home agent receives a reply message corresponding to the reply request message through the first network, the home agent detects that the configuration of the tunnel for transmitting and receiving the packet through the first network can be deleted, and deletes the configuration of the tunnel.
摘要:
A facility control system for controlling devices shared in spaces, a plurality of operation units being equipped in the spaces respectively, each operation unit configured to input a operation request for operating the devices, calculates a priority level of each space during the reservation time of each space based on at least one of the use purpose of each space and the attribute information of each user of each space, detects a type of the operation request input from each operation unit provided in each space, detects, whenever the type of the operation request is detected for each space, a collision between types of the latest operation requests detected for respective spaces based on the types, and operates the devices according to one of the types which is detected for one of the spaces whose priority level is highest when the collision is detected.
摘要:
At a node device, after an exchange procedure for exchanging a security association information is carried out, the security association information is stored in a memory unit while a management information including the destination address, the identification information, and an information regarding a valid period of the security association information is stored in a non-volatile medium, such that it is possible to recover the normal state quickly without damaging the safety, when a temporary operation trouble occurs at one node under an environment in which a plurality of nodes are carrying out communications safely by using a prescribed security protocol.
