A dynamic route splitting system includes a control unit configured to monitor reception quality of a traffic flow on a network and carry out dynamic route setting to an optional node in the network, and a dynamic route splitting unit configured to be arranged in the node configured to relay the traffic flow on the network or a reception terminal as a destination of the traffic flow. The control unit selects at least the node splitting the traffic flow based on the reception quality of the traffic flow on the network and instructs splitting traffic flows to the dynamic route splitting unit in the selected node. The dynamic route splitting unit is provided in the node and includes a monitoring section that monitors the traffic flow having reached the node when being provided in the node in the network, and to notify a monitoring result to the control unit.
