Abstract: When a plurality of services are enjoyed by a single terminal, a communication regulation caused by another service has influence on enjoyment of another service. A service provider and a mobile communication provider are affiliated with each other and newly provide an affiliated service in which a communication fee for a service use is borne by the service provider to a user. Conventional communication and affiliated service communication are performed on a single communication line of the user together, and communication control is performed in units of services such that a service quality of the affiliated service is maintained. It is implemented by affiliating a communication log and contract information between business operators and performing communication identification using user information at the time of a contract as a key.

Abstract: A monitoring system comprises: a measurement unit; and an analysis unit, wherein the measurement unit measures traffic information relating to messages inputted to a device to be monitored and messages outputted from the device to be monitored, and wherein the analysis unit calculates one or more indices on the basis of a prescribed relational expression and the measured traffic information, and detects that a specific change in state has occurred in the device to be monitored on the basis of the indices or a comparison between a change in the indices and a threshold.

Abstract: 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.

Abstract: 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<m<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.

Abstract: In a communication system in which a plurality of communication apparatuses perform communication via a communication network, a network abnormality detection system dynamically creates a monitoring rule during operation without defining information (monitoring rule) regarding communication to be monitored in advance and perform a collection process and an abnormality determination process quickly even when an amount of information to be monitored is vast. The network abnormality detection system copies packets transmitted at predetermined measurement positions in the communication network, calculates communication statistics information at each measurement position from the copied packets, analyzes one or more pieces of communication statistics information, and detects occurrence of communication abnormality.

Abstract: A monitoring device executes: aggregating a number of messages for each type of message transmitted or received at nodes using test results; classifying the respective messages into either an original message that serves as an origin among messages transmitted and received by a system to be monitored, or a generated message that is generated in the system when the original message is transmitted to any of the plurality of nodes; analyzing a relationship between the original message and the generated message on the basis of a number of messages classified as the original message and a number of messages classified as the generated message, thereby creating a matrix indicating the relationship between the original message and the generated message; and determining that the system has undergone a failure if a value of an element inside the matrix is outside of a normal range.

Abstract: An address translator includes an SIP message detecting function. Upon detection of an SIP message, the address translator sends the SIP message to an SIP address translator. The SIP address translator extracts addresses for translation, and makes a query to the address translator. The SIP address translator translates an IP address included in the SIP message, using translation information of the address translator. Thus, an SIP communication is accomplished between terminals belonging to different regions in association of the address translator and the SIP address translator.

Abstract: A system high in availability which includes plural file servers and local disks is realized. A distributed file system has plural file server clusters that perform any one of file storage, file read, and file deletion according to a request. A gateway device mediates requests between a client device that transmits a request including any one of file storage, file read, and file deletion, and the distributed file system. The gateway device includes a health check function unit that monitors an operating status of the file server cluster, and a data control function unit that receives the request for the distributed file system from the client device, and selects one or more of the file server clusters that are normally in operation, and distributes the request to the selected file server clusters.

Abstract: A node, when an object request message includes a location ID of a destination, sets the location ID of the destination as a search key to search the location-ID forwarding table thereof and forwards the object request message to a node that is a next hop obtained as the search result; and when the object request message does not include the location ID of the destination, sets the object ID included in the object request message as a search key to search the object-ID forwarding table thereof to forward the object request message to the node that is the next hop obtained as the search result.
