20140064056 | NETWORK MANAGEMENT APPARATUS, NETWORK MANAGEMENT METHOD, AND NETWORK MANAGEMENT SYSTEM - 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. | 03-06-2014 |
20140321460 | COMMUNICATION PATH SWITCHING DEVICE, COMMUNICATION PATH SWITCHING METHOD AND COMMUNICATION PATH SWITCHING PROGRAM - A communication path switching device is configured to determine whether or not a specified network device where exclusion from a communication path or addition to the communication path is specified through an input device can perform path switching based on the individual pieces of information on a coupling configuration and a presence or absence of an independent control function; refer to a storage device for the individual pieces of information on the coupling configuration and a coupling policy to change the coupling policy according to a result of the determination; and processing of issuing, according to the result of the determination and the individual pieces of information in the storage device, a path switching instruction to a network device having the independent control function and a network device not having the independent control function that are path switching targets on a communication path directed to the specified network device. | 10-30-2014 |
20150180715 | METHOD OF CONSTRUCTING LOGICAL NETWORK AND NETWORK SYSTEM - There is provided a method of constructing a logical network which determines a network apparatus of a deployment location and a middlebox apparatus when the logical network is constructed on a physical network to which the network apparatus, the middlebox apparatus, and a physical server are coupled, in which an abstract configuration of the logical network and logical network information including a performance requirement with respect to a configuration element are received, and the network apparatus which become a deployment location of the logical network and the middlebox apparatus are determined according to the abstract configuration of the logical network and the performance requirement. | 06-25-2015 |
20150244643 | DATA CENTER RESOURCE ALLOCATION SYSTEM AND DATA CENTER RESOURCE ALLOCATION METHOD - A data center including: a data center infrastructure including at least one service network accessed by a terminal of a logical infrastructure user and a terminal of a resource user, at least one infrastructure network accessed by the terminal of the resource user, and at least one resource coupled to the service network and the infrastructure network; and a resource management apparatus for managing the infrastructure network, the service network, and the at least one resource, the resource management apparatus being configured to: generate, in response to a request, a logical service network, which is created by virtualizing the service network, a logical infrastructure network, which is created by virtualizing the infrastructure network, and a logical infrastructure in which the at least one resource is allocated to the logical service network and the logical infrastructure network; and provide the logical infrastructure to the terminal of the logical infrastructure user. | 08-27-2015 |
20150280961 | NETWORK EXTENSION SYSTEM, CONTROL APPARATUS, AND NETWORK EXTENSION METHOD - It is provided a network extension system configured to couple a first network system in which a first gateway and a first host computer are capable of communicating to and from each other to a second network system in which a second gateway and a second host computer are capable of communicating to and from each other, the second network system comprising a management apparatus, the network extension system comprising a control apparatus configured to control the management apparatus, the control apparatus being configured to execute: acquisition processing of acquiring network address information of the first host computer; and assignment processing of controlling the management apparatus to assign the network address information of the first host computer that has been acquired in the acquisition processing to the interface that is coupled to the second host computer among the group of interfaces of the second gateway. | 10-01-2015 |
20150304200 | TRAFFIC INFORMATION COLLECTION SYSTEM AND COLLECTION CONTROL NODE - In a traffic information collection system in which a collection node collecting collection information regarding traffic acquired by nodes on a network identifies a collection point of the collection information, a transmission node to transmit the collection information from a designated transmission port and a collection control node are included. The collection control node manages a connection relation of the transmission port of the transmission node and a reception IF of the collection node. The collection control node determines the reception IF of the collection node receiving the collection information acquired at a designated collection point of any node. The collection control node designates the transmission port connected to the determined reception IF with respect to the transmission node and outputs the collection information from the designated transmission port. The collection control node informs the collection node of correspondence information of the collection point and the reception IF. | 10-22-2015 |
20160043899 | MANAGEMENT COMPUTER, MANAGEMENT METHOD, AND NON-TRANSITORY RECORDING MEDIUM - A management computer coupled to a network device comprises: a processor; and a storage unit that stores effect determination information that defines conditions for determining an effect of an operation by the network device, the conditions being applied to a combination of setting items for the network device, and wherein the processor executes: to select, from among the combination of setting items, a specific combination matching a combination of a first setting item for the network device and a second setting item associated with the first setting item; to determine whether or not the combination of the first setting item and the second setting item satisfies the conditions applied to the specific combination if the specific combination is selected; to identify the presence or absence of an effect resulting from an operation of the network device on the basis of determination results; and to output identification results. | 02-11-2016 |
20160094393 | MANAGEMENT APPARATUS, METHOD OF MANAGING A NETWORK AND STORAGE MEDIUM - A management apparatus that manages a network apparatus having a packet control function, wherein the network apparatus has configuration information that sets the control function, and wherein the management apparatus has: parameter information that manages settings of the control function of the network apparatus; and an inconsistent data detection module that obtains the configuration information from the network apparatus, and upon comparison of the configuration information with the parameter information, detects, as inconsistent data, information that does not match. | 03-31-2016 |
