Patent number: 9112779Abstract: In a network system in which a large number of terminals that transmit information exist and data extraction is performed via a wide area network, when data filtering is performed by using terminals called entrance nodes, existing in front of the wide area network, efficient operation of the entrance nodes is a goal to achieve. In one implementation, when an entrance node has detected an alteration to a configuration of diverse resources attached to it, it updates management information by communicating with other entrance nodes existing in the neighborhood. In a further implementation, through a query and reply exchange about allocations of filtering and quick response processes to be executed by entrance nodes, reallocating process items, pre-filtering of necessary data, and relaying data between entrance nodes are performed.Type: GrantFiled: March 30, 2012Date of Patent: August 18, 2015Assignee: Hitachi, Ltd.Inventors: Masaki Yamada, Yuji Ogata, Nobuyuki Muranaka

Patent number: 8879577Abstract: Provided is a monitoring system which can perform priority control in accordance with the wideband limitation. A priority/filter type selection processing unit (37) of a network interconnection device (11), which connects a local network (14) and a wide area network (10), selects a transmission data selection processing unit (38) on the basis of the priority level definitions of a transmission data in accordance with an event status, and a data compression method in association with the event status and the wide area network communication status, and selects and controls a filtering processing unit (33). As a consequence, the communication bandwidth in a wide area network is reduced.Type: GrantFiled: February 14, 2011Date of Patent: November 4, 2014Assignee: Hitachi, Ltd.Inventors: May Takada, Yuji Ogata, Masaki Yamada, Nobuyuki Muranaka

Patent number: 8601593Abstract: The consistency between an application output destination and a permitted user for an I/O device section is ensured when a user deploys an application for processing and outputting input data onto an entrance node. The entrance node includes an output destination/user table that manages correspondence between an application output destination and a user. The output destination/user table stores information about the output destination used for each user who uses the entrance node. An application deployment management function of a processing section in the entrance node determines whether application deployment can be accepted from a user. To do this, the application deployment management function specifies a user corresponding to the output destination for the application from the output destination/user table and verifies that the user is consistent with a user permitted for an I/O device in the I/O device section used by the application.Type: GrantFiled: November 16, 2010Date of Patent: December 3, 2013Assignee: Hitachi, Ltd.Inventors: Nobuyuki Muranaka, Yuji Ogata, Koki Nakashiro, Masaki Yamada

Publication number: 20120177046Abstract: In a network node, when highly sophisticated processing such as filtering is implemented, a phenomenon in which, as the processing becomes more highly sophisticated, a time required for the processing becomes long, and as a result, a delay time of packet forwarding is prolonged, is prevented from occurring. The network node of the present invention performs packet forwarding control for controlling a destination of a packet in parallel with packet forwarding processing for searching for the destination, so that the network node realizes high-speed packet forwarding processing while performing forwarding control by packet monitoring.Type: ApplicationFiled: January 5, 2012Publication date: July 12, 2012Applicant: HITACHI, LTD.Inventors: Masaki YAMADA, Yuji OGATA, Nobuyuki MURANAKA
