Data collection system

A gateway device disposed at front stage before a server has a dispersion rule of data dispersed on server side and analyzes communication data to specify a server to be accessed finally, so that identification information of the specified server is added to packet option of IP layer to thereby omit higher-rank routing processing than IP layer of gateway devices on the way. Consequently, transfer processing of a gateway device at back stage can be performed at high speed and access passing through a network route intended by manager is possible.

Access relay method and access gateway device

This invention provides an apparatus that associates a location where a terminal uses communication or travel route in use of the communication, with a connection destination of the terminal. The apparatus includes a communication log analyzer that aggregates communication logs collected by network apparatuses that constitute the mobile network and analyzes it. The communication log analyzer estimates travel route of the terminal connected the network using: log information generated by a base station to be connected to the terminal at the time of starting the connection, log information generated by a base station to be connected to the terminal at the time of a handover of the connection, and log information generated by a base station connected to the terminal at the time of detaching the connection.

A load balancing system for performing stable processing and high reliability includes a management device which acquires time information indicating the time required in past processing on each of n processing devices, estimates a required time required for each processing devices to process processing target information based on the time information thereby obtaining an estimated time, and transmits estimated time information indicating a relationship between the estimated time and the processing device to a load balancing device. The load balancing device determines m (1&#x3c;m&#x3c;n) processing devices that process the processing target information based on the estimated time information and transmits the processing target information to the designated processing devices. A processing result determination device receives results from the processing devices, estimates a true value from the results to obtain an estimated value, and transmits the estimated value to a subsequent-stage processing device that processes the estimated value.

Processing control system, processing control method, and processing control program

A technique capable of preventing an increase in the load of a system and a IP-based network that perform both a process of transmitting information in real time and a process of storing and searching history information and of improving the scalability of the system. A video surveillance system includes: plural cameras that capture images; a monitoring apparatus that displays the images captured by the cameras; an information generating apparatus that generates information for searching the images captured by the cameras; and a search apparatus that searches the images captured by the cameras. The information generating apparatus acquires the images captured by the cameras, generates retrieval data from the acquired images, and transmits the generated retrieval data to the search apparatus. The search apparatus stores the retrieval data received from the information generating apparatus in a storage device, and notifies the monitoring apparatus that the retrieval data has been stored.

Video surveillance system and method using IP-based networks

A method in which a mail server for receiving mails manages sequence management information that records the sequence of mails stored in a data store server and the times at which a mail server sends the mails to a destination server, wherein the sequence management information is so managed as to satisfy the two conditions: one is to make not greater than a predetermined number the number of entries in any one of respective pieces of the divided sequence management information resulted by dividing the sequence management information into a plurality of pieces, each entry being included in each divided sequence management information piece and defined as a combination of key having the mail body of a certain mail as its value, and the time at which the certain mail is sent to the destination server.

In a system with a terminal sending a request, when a load distributing unit distributes the request to many service providing apparatuses, the load distributing unit becomes a bottleneck of performance and/or a single point of failure. When the load is distributed to the service providing apparatuses without using the load distributing unit, a particular function is required on the terminal side to appropriately select one of apparatuses.

A vehicle-onboard apparatus system, comprises a portable terminal and a vehicle-onboard machine that are configured to be coupled to each other for communication. The portable terminal and the vehicle-onboard machine each store operation logs including operation contents thereof. When an operation of the vehicle-onboard machine and an operation of the portable terminal relate to each other, an operation log resulting from the operation of the vehicle-onboard machine and an operation log resulting from the operation of the portable terminal are associated with each other by first identification information. The vehicle-onboard machine makes a user to recognize the first identification information corresponding to an operation causing detected predetermined state. When the portable terminal receives an input of the first identification information presented by the vehicle-onboard machine, the portable terminal acquires the operation log associated with the input first identification information. The portable terminal analyzes the acquired operation log.
