Abstract:
1. A frame transmitting apparatus that transmits a frame having a header area, a payload area, and a buffer area between the header area and the payload area to an other apparatus, the frame transmitting apparatus comprising: a receiver to receive the frame transmitted from the other apparatus; a processor that is operative to detect an amount of data accumulated in the frame transmitting apparatus, to embed idle-frame-insert request information in the buffer area between the header area which stores control information pertaining to operational management of frame transmission and the payload area which stores Point to Point Protocol frames within the frame, the idle-frame-insert request information requesting inclusion of an idle frame in the payload area of a received frame, when the amount of data detected exceeds a threshold value, to determine whether the idle-frame-insert request information is included in the buffer area of the received frame, and to insert an idle frame in the payload area of the frame to be transmitted to the other apparatus, when the idle-frame-insert request information is included in the buffer area; and a transmitter to transmit the frame including the idle-frame-insert request information in the buffer area to the other apparatus, the frame including a virtual container frame or a synchronous-transport-signal frame, without halting transmission of the data to the other apparatus.
