ABSTRACT:
Disclosed is a transmitter apparatus which creates a PI frame (Pause-In frame) and a PO frame (Pause-Out frame) and transmits each frame to a router for executing flow control. When creation of a PI frame is commanded from a band controller, or when a flow-control start request is detected from a signal that enters from a transmission line, the transmitter apparatus sends a PI frame to a router to allow execution of flow control. When creation of a PO frame is commanded from the band controller and, moreover, a flow-control halt request is detected from a signal that enters from the transmission line at such time that the router is performing flow control, the transmitting apparatus creates the PO frame and sends it to the router to halt flow control.
