A video distribution device according to an embodiment is a video distribution device that distributes videos from a plurality of cameras installed in each of a plurality of vehicles that perform autonomous driving to a terminal, and includes a probability of collision calculating unit that calculates a probability of collision indicating a probability of the vehicles colliding with an object by a predetermined time of day, a selecting unit that selects, out of the videos of the plurality of cameras, video from a camera installed in a vehicle of which the probability of collision is highest, and a control unit for setting video quality of the video of the selected camera to be high.

Video distribution apparatus, video distribution method and program

Backup system and method that can determine a backup destination in consideration of disaster are provided. There are provided: a data acquisition unitthat acquires disaster information, network information, and node information; a replication group construction unitthat generates, based on the disaster information, and the like, replication group information including association information between a first node that stores original data and one or more second nodes that are candidates for backup destination of the original data, and saves the replication group information in a storage unit; a replication destination node calculation unitthat, when executing backup of the original data, calculates the second node as backup destination from the replication group; and a replication processing unitthat replicates and stores the original data into the storage of the second node.

Backup system, method therefor, and program

A system and method capable of efficiently using and operating resources and allowing a cluster satisfying requirements of functions/services provided to terminals to be configured of multi-access edge computing (MEC) servers are provided. A clustering systemincludes a monitoring unitconfigured to monitor a usage status of MEC servers and a network and store telemetry information in a storage unit, a cluster planning request unitconfigured to acquire non-telemetry information such as provision area information and requirement information of functions/services and deployment information of the MEC server, store the non-telemetry information in the storage unit, a cluster planning unitconfigured to set a virtual region including one or more bases satisfying a provision area and requirements on the basis of each piece of information in the storage unitand calculate a cluster plan for providing the functions/services from a plurality of MEC servers disposed at the base belonging to the virtual region, and a cluster construction unitconfigured to perform a clustering process on the basis of the cluster plan.

Clustering system and clustering method for providing services using multi- access edge computing servers

A resource allocation device includes: a course estimation unit that estimates a course of each mobile terminal based on a location of a mobile terminal acquired from a network device, and estimates a probability that each mobile terminal is located in each area at time of prediction; a determination unit that calculates, for each area, the number of mobile terminals in the area using the probability and determines whether the maximum value of an overcommit ratio for each area exceeds an upper limit; and an execution unit that executes the allocation or release of resources to an MEC server group located in each area when the maximum value of the overcommit ratio is equal to or less than the upper limit, and refrains from executing the allocation or release of the resources to the MEC server group when the maximum value of the overcommit ratio exceeds the upper limit.

Resource allocation apparatus, resource allocation method and resource allocation program

A packet processing system and method for enabling real-time packet processing while preventing an unnecessary delay increase are provided. A terminal-and a terminal-that transmit different types of packets in real time, a communication devicethat processes packets transmitted by the terminal-, and a packet processing devicedisposed in a communication path of the packet from the terminal-and the terminal-to the communication device. The packet processing devicedetermines a processing method for the packets received from the terminal-based on the packets received from the terminal-, creates a processing method determination table, and creates a processing method list. The terminal information packet processing unitprocesses the packets received from the terminal-per packet unit based on the processing method list.

Packet processing system and method

The present invention provides an inrush current suppression circuit that is provided in an electric power conversion apparatus and suppresses inrush current that occurs when power is turned on, the electric power conversion apparatus including an inverter circuit and a drive power circuit that generates direct voltages of two levels as drive voltages, wherein the inrush current suppression circuit includes: an inrush current prevention resistor disposed between a converter circuit that generates DC power to be supplied to the inverter circuit and a smoothing circuit; a relay connected in parallel to the inrush current prevention resistor; and a relay control circuit that applies to the relay a higher direct voltage to shift the relay to a closed state, and after the relay is set to the closed state, applies to the relay a lower direct voltage to retain the closed state.
