  • Patent number: 11641315
    Abstract: An object is to provide a traffic monitoring method, a traffic monitoring apparatus, and a program capable of efficiently merging data structures of each of the cores in a multi-core environment without reconstructing a data structure, retrieving a data structure, and adjusting the RSS function. In the traffic monitoring method according to an embodiment of the present invention, the elements of the data structures formed in the cores are compared for each item, and statistic values in the elements are brought together into any one of the elements, and the statistic values of the other elements are set to zero. Redundant elements between the data structures can be removed by ignoring elements having a statistic value of zero at the time of merging data structures.

  • Publication number: 20230013105
    Abstract: It is an objective of the present disclosure to reduce computational complexity for obtaining a network topology configuration capable of efficiently accommodating a plurality of traffic demands assumed between nodes present in a network. A device of the present disclosure includes: a computation traffic generation unit that creates a traffic demand matrix whose elements are values individually obtained by demands between nodes present in a target network area from a plurality of traffic demand matrices created based on predicted traffic demands between the nodes; and a network topology generation unit that generates a network topology based on the traffic demand matrix generated by the computation traffic generation unit and port information of the nodes in the network area.

  • Publication number: 20220303645
    Abstract: An object of the present disclosure is to propose a technique to enumerate intermediate configurations at high speeds. A configuration enumeration device 10 according to the present disclosure enumerates a network configuration in an input layer 21, an intermediate layer 22, and an output layer 23 that minimizes the number of mechanical patch panels provided in mechanical patch panels, by using a-quasi-nonblocking configurations, where a being 0 indicates a rearrangeably nonblocking configuration and ? being 1 indicates a strictly nonblocking configuration, for 0???1, when a minimum value C of wiring capacity of mechanical patch panels having the input layer 21, the intermediate layer 22, and the output layer 23 is obtained.

  • Patent number: 11095519
    Abstract: An object of the present disclosure is to provide a network device and a method for setting the network device that can, in developing functional modules, perform abnormality detection based on statistical information and setting verification in consideration of a dependency relationship between the functional modules and statistical information and can address a change in a policy in the setting verification and a change in a condition in the abnormality detection. In the network device according to the present disclosure, an existing setting of each module, external information, a dependency relationship, and a policy are collected at one location (setting verification unit) by using a common language. When a new setting is made to the modules, a new dependency relationship is set, or new external information is acquired, the new setting is sent to the setting verification unit and checked against the existing setting, the external information, and the dependency relationship.
