Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026613
Kind Code:
A1
Abstract:
The present invention enables transfer with less waiting time. This control device is provided with a routing control unit, transmission queues, and a plurality of controllers, wherein the routing control unit is provided with a buffer, a normal transmission unit which outputs frames other than a frame to be retransmitted among inputted frames to the transmission queue of the controller corresponding to a transfer destination network, and if the controller corresponding to the transfer destination network is in a full state in which no more frames can be stored in the transmission queue, designates the inputted frames as frames to be retransmitted and stores the inputted frames in the buffer; and a signal handling unit which, upon receiving a cancellation signal indicating that the full state has been cancelled from any of the plurality of controllers, outputs a frame to be retransmitted, the transfer destination of which is a network corresponding to the controller that has transmitted the cancellation signal, to the transmission queue of the controller that has transmitted the cancellation signal, the controller transmitting the cancellation signal to the signal handling unit when the full state has been cancelled.
