  • Patent number: 12040995
    Abstract: A control device that performs resource allocation to a network including a transmission device, one or more transfer devices, and a reception device as nodes, the control device including a schedule database unit that holds schedules of time slots not allocated to specific communication, the schedules being set in advance for respective nodes of the network, and a schedule processing unit that, in a case where a communication request is received, selects a time slot that satisfies a transmission request amount of the transmission device on the basis of remaining transmittable amounts of respective time slots in the schedules and notifies the transmission device of a selected time slot.

  • Publication number: 20230134535
    Abstract: In an information processing device 100 including a GPU learning cluster, the GPU learning cluster includes a main container (first execution unit) 4 that executes a learning program of a job submitted by a user inside the job; and a helper container (second execution unit) 6 that executes processing of making a private network connection to a storage of the user to mount the storage inside the job. The main container (first execution unit) 4 reads data to be learned from the mounted storage, and executes the learning program by using the data to be learned.

  • 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.

  • Patent number: 11271847
    Abstract: An object is to provide a multipoint distribution system, a distribution method, a management apparatus, and a program which determine whether or not to switch between a current-use system and a backup system in consideration of the importance levels of distribution destinations. The multipoint distribution system according to the present invention includes a distribution destination system importance level database that stores the importance levels of distribution destinations. When a distribution destination not able to communicate with a current-use video distribution system is detected, the multipoint distribution system performs switching from the current-use video distribution system to a backup video distribution system only upon determining that the distribution destination is important by referring to the distribution destination system importance level database.

  • 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.
