Abstract: An object of the present disclosure is to perform appropriate communication quality control even when a terminal out of management of a controller is connected to an access point. The present disclosure is a control system for controlling traffic of a wireless network, the control system including: a terminal and an access point that mutually transmit a packet via the wireless network; and a controller that performs transmission control with respect to the terminal and the access point, in which the controller notifies the access point of information of a terminal under management of the own device, and the access point collates information of the terminal a notification of which has been given with information of a terminal connected to the own device, and suppresses notification of transmission permission to an unmanaged terminal different from a terminal under management of the controller.

Abstract: An object of the present disclosure is to enable network control to be executable that does not deteriorate experience quality of a user even in a case where the user uses a terminal. A communication processing device according to the present disclosure, when detecting occurrence of network control that is different from a user controlled application, collects user information indicating a state of a user that uses a terminal, predicts an experience quality change of the user in a case of executing the network control using the user information obtained by the collection, and executes the network control on the basis of an experience quality change amount of the user obtained by the prediction.

Abstract: An object is to provide a communication apparatus, a communication method, and a program capable of avoiding an increase in network load when input traffic continues to be large and a communication delay when input traffic is very small. A communication apparatus according to the present invention prepares three token buckets and can transfer, discard, or hold a packet in accordance with the amount of tokens in each token bucket. This enables the communication apparatus to operate so as not to exceed a set maximum bandwidth when large traffic is received for the delay guarantee shaping. Further, When the maximum bandwidth is exceeded, the communication apparatus can select whether to discard a packet to prioritize a delay guarantee or to hold a packet to prioritize no loss of packets. Furthermore, the communication apparatus can immediately transmit a packet without increasing a communication delay when input traffic is very small.

Abstract: An object of the present disclosure is to continuously and easily grasp a communication quality such as RTT of application communication itself without depending on a protocol type. A communication system of the present disclosure holds a DPI rule for each application in a DPI rule management server in advance, duplicates a packet of a designated application extracted based on a filtering rule for extracting the packet, extracts information from the packet based on a DPI rule for the application acquired from the DPI rule management server, and calculates a communication quality based on the extracted information.

Abstract: An object of the present disclosure is to reduce traffic burstiness in a TCP without causing a window size expansion delay and a decrease in maximum throughput. A system of the present disclosure is a communication system for transmitting a packet from a transmission terminal to a reception terminal, the communication system including a congestion control unit that performs congestion control of a packet transmitted from the transmission terminal, and a delay control shaping unit that changes a set value of delay control shaping based on a setting of a congestion window size on which the congestion control unit performs congestion.

Abstract: The present disclosure aims to enable a total of 127 or more USB devices to be connected on the same network regardless of connection sites. A USB connection control system of the present disclosure is a USB connection control system including a plurality of USB-network conversion devices and a management device being connected to each other via a network, in which the management device holds, per user, connection information defining a connection destination of a USB device connected to the USB-network conversion device, and at least one of the plurality of USB-network conversion devices receives, from the management device, the connection information corresponding to identification information unique to the at least one of the plurality of USB-network conversion devices and communicates with a to-be-connected USB-network conversion device based on the received connection information, and to establish connection with a USB device that is connected to the to-be-connected USB-network conversion device.

Abstract: An aspect of the present disclosure is a biosensor information collection system S including: a biosensor terminal 1-N that is to be attached to a living body and outputs sensor information on the living body; a hub terminal 2 that is to be attached to the living body and collects the sensor information on the living body, the biosensor terminal 1-N and the hub terminal 2 performing communication therebetween near a surface of the living body, the hub terminal 2 including: a reception intensity determination unit 26 that determines whether a reception intensity from the biosensor terminal 1-N coincides with a predetermined intensity with an allowable margin or deviates from the predetermined intensity beyond the allowable margin; and a sensor information request unit 25 that requests the sensor information on the living body of the biosensor terminal 1-N when the reception intensity from the biosensor terminal 1-N coincides with the predetermined intensity with the allowable margin and suspends the request fo

Abstract: It is an object to the present invention to provide a control system, a control method, a controller, and a program which allow a band allocated to each of traffic flows to be guaranteed. According to the present invention, terminals and an access point each store packets to be transmitted to buffers therein on a traffic flow basis and notify the controller of the amount of stored packets, the controller determines transmission time and a transmission amount of packets on a traffic flow basis according to the notified packet amount to notify a corresponding terminal and the access point of the time and amount, and the terminal and the access point transmit packets according to the notified transmission time and transmission amount.

Abstract: An object is to provide a network management system and the like capable of being introduced into an existing network to ascertain an instantaneous traffic variation in the network. The scheme of the present invention uses a shaping function included by each edge apparatus. The shaping function controls packet transmission in a millisecond order. The network management apparatus according to the present invention adds up the amount of transmitted packets for each control period reported by each edge apparatus and estimates this as an instantaneous traffic amount in the network. In the scheme, it is only necessary to add one network management apparatus to an existing network and to cause each edge apparatus to report the amount of transmitted packet to the network management apparatus.
