  • Patent number: 9094303
    Abstract: Interdomain federation, generation or management of a virtual network (slice) that extends among domains can be performed without changing a function of a server or a node of a network domain without a function to manage the other domain. Pseudo node receiving a management message with the same protocol as a general node is added, in interdomain management information from an own domain, the other domain part in management information is received as the management information by the pseudo node (the other domain part is concealed) and when interdomain management information is transmitted to the other domain through the pseudo node by a federation protocol and the pseudo node and the interdomain management information is received from the other domain, the other domain part in the management information is bound as the management information of the pseudo node and transmitted to a management server of own domain.

  • Patent number: 9065728
    Abstract: Systems, methods and devices for failure analysis are provided. Using aggregation flow mining (AFM) or a similar method, an integrated mining of flow (IMF) acquires, from each router to be tested, information relating to each flow. The IMF, in relation to each of the routers, obtains distributions of statistical information such as throughput or difference for each flow; calculates, in relation to each of the distributions, a Mahalanobis distance in relation to the expected value of a reference distribution; and makes a comprehensive assessment of the distributions to perform a fault determination. When the fault determination is performed, a normal value of the distribution used for comparison is acquired from AFM and updated through feedback as needed. After the results of fault determination relating to other routers are assessed, the expected value of the standard deviation and the average value of the reference distribution used for comparison are updated.

  • Publication number: 20130329571
    Abstract: Conventional network tomography techniques do not allow the location or cause of a failure to be specified, and false positives are common due to lack of information. Using aggregation flow mining (AFM) or a similar method, an IMF (102) acquires, from each router (105) to be tested, information in relation to each flow. The IMF, in relation to each of the routers, obtains distributions of statistical information such as throughput or difference for each flow; calculates, in relation to each of the distributions, a Mahalanobis distance in relation to the expected value of a reference distribution; and makes a comprehensive assessment of the distributions to perform a fault determination. When the fault determination is performed, a normal value of the distribution used for comparison is acquired from AFM and updated through feedback as needed.

  • Patent number: 8396986
    Abstract: In cooperation between each data center and a WAN, virtual machine migration is carried out without interruption in processing so as to enable effective power-saving implementation, load distribution, or fault countermeasure processing. Each node located at a boundary point between the WAN and another network is provided with a network address translation (NAT) function that can be set dynamically to avoid address duplication due to virtual machine migration. Alternatively, each node included in the WAN is provided with a network virtualization function; and there are implemented a virtual network connected to a data center for including a virtual machine before migration, and a virtual network connected to a data center for including the virtual machine after migration, thereby allowing coexistent provision of identical addresses. Thus, the need for changing network routing information at the time of virtual machine migration can be eliminated, and a setting change for migration accomplished quickly.

  • Patent number: 7636311
    Abstract: There is a need for applying an appropriate QoS setting to a complex information platform apparatus capable of flexibly changing an apparatus configuration so as to ensure an intra-apparatus communication band and realize management communication independence. Multiple processing modules are combined to construct one or more processing units with different apparatus types. An apparatus template management table prepares multiple levels of setting specifications with different ensured bands for intra-apparatus communication corresponding to each apparatus type. One set of setting specification is selected from multiple levels of setting specifications prepared for an apparatus type settled at the time of configuration setting. A QoS setting management table is generated based on the selected setting specification. When the configuration is set or changed, setting verification means verifies whether or not a total of ensured bands associated with each adapter is within an allowable range.
