Abstract: To solve the above problem, the present invention aims to provide a controller, a communication system, a control method, and a program capable of performing transmission scheduling to avoid mutual interference in a plurality of wireless networks.
A controller 13 according to the present invention includes a scheduler SCH3 that calculates a transmission schedule for packets to be transmitted from buffers (FB1, FB2) on the basis of the amount of packets stored in a database DB in each predetermined period, and, when calculating the transmission schedule, imposes a restriction to prevent a total amount of packets to be transmitted from all the buffers (FB1, FB2) included in a network NW #j from exceeding the product of the throughput of each network NW #j and the predetermined period.-

Abstract: An object of the present disclosure is to enable band allocation on a traffic flow basis even in a real wireless network in which a terminal repeats connection/disconnection in association with movement of a person or the like.
The present disclosure relates to a control system for controlling traffic in a wireless network. The control system includes a controller that performs transmission control on a terminal and an access point. Before the access point establishes a connection with the terminal, the controller establishes a connection with the terminal using a connection sequence according to a protocol available in the wireless network, and acquires, from the terminal, information about a node number and a flow-based buffer of the terminal. After the access point establishes a connection with the terminal, the controller performs transmission control for each traffic flow accumulated in the flow-based buffer of the terminal using the acquired information about the node number and the flow-based buffer of the terminal.-

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: 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.-
