摘要： Provided are a communication control device, a communication control system, a communication control method, and a communication control program that make it difficult to reduce band utilization efficiency. In an OLT server 9b that is a communication control device, a transmission time storage unit 12 stores a transmission time of an optical signal between each ONU 3 and OLT 4. An optical transmission control unit 13 generates control information for controlling transmission start and transmission end of optical signals in each ONU 3. A failure detection suppression unit 15 calculates a first time at which the reception of the optical signal from an ONU 3p ends using control information and a transmission time. The failure detection suppression unit 15 calculates a second time at which synchronization processing ends after the reception of the optical signal from an ONU 3q that transmits the optical signal next after the ONU 3p is started using the synchronization time until the synchronization processing acquired by a synchronization time acquisition unit 14 ends. The failure detection suppression unit 15 causes the failure detection unit 11 that detects a link failure in an OLT 4 to suppress detection of a link failure from the first time to the second time.

摘要： The signal transfer device receives a periodically transmitted periodic signal and transfers the periodic signal in a reserved window. A control device that controls a signal transfer device includes a storage device configured to store reference information indicating a transmission amount and a transmission period of the periodic signals of each of a plurality of flows received by the signal transfer device. The control device further includes a processor that executes window setting processing based on the reference information. In the window setting processing, the control device sets a schedule of a plurality of windows for each of the plurality of flows in the signal transfer device based on the reference information, and instructs the signal transfer device to reserve the plurality of windows according to the schedule.

摘要： A user terminal 12-1 can wirelessly or preferentially connect to a router 14 to communicate with an upper network 18, and can communicate with another network 20 via a mobile line. An ONU 16 generates a disconnection notification in a case where congestion exceeding a reference is recognized in the PON communicating with the upper network 18, and generates a connection notification when the congestion is resolved. The router 14 stores the user terminal 12-1 that can communicate with another network 20 among the user terminals 12-1 to 12-4 being connected. In addition, the router 14 disconnects the connection with the user terminal 12-1 that can communicate with another network 20 when the disconnection notification is generated, and attempts reconnection with the user terminal 12-1 that has been disconnected when the connection notification is generated.
