  • Patent number: 9485166
    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.

  • Patent number: 9219650
    Abstract: A network management apparatus is designed so that when reassigning the existing address, the network management apparatus extracts a link with the largest link cost from among links comprising the network based on the network configuration information and specifies a flow routed though the extracted link based on the statistic information; when receiving a path change request and a via link request to request a via link with respect to the specified flow from an external terminal, the network management apparatus selects either one of addresses of an address pair of the specified flow as a change target address; and when changing the selected change target address, the network management apparatus changes the change target address to a candidate address to be assigned by selecting an address, which is routed through a link included in the via link request and has not been assigned, as the candidate address to be assigned.

  • Patent number: 8145687
    Abstract: Since no access history is generated for when a file update which makes use of a copy and paste function is performed, it is difficult to detect the file that served as the reference source during the update. Hence, the present invention is provided to manage a client access history for each file that is stored in a storage device, and detect a file, which has been accessed between a time when a corresponding user logs into the storage device and a time when an updated file is updated based on information of the access history, as the reference source for the updated file.
