摘要： A first node and a second node transmit packets to a third node via a switch. The packets are buffered in a Tx buffer in the switch and then transmitted to the third node.
When the third node detects a sign of congestion at the Tx buffer based on the reception frequency of the packets, it is recognized, from transmitter addresses included in the received packets, that the nodes transmitting the packets to the third node are the first node and the second node, and a control packet for a transmission stop request is transmitted to the first node and the second node. On receiving the control packet for a transmission stop request, the first node stops transmission of only packets addressed to the third node. On receiving the control packet for a transmission stop request, the second node stops transmission of only packets addressed to the third node.

摘要： A transmission apparatus includes a network-side interface unit configured to receive a signal transmission frame into which a client signal is arranged from each of a working line and a protection line of a network, and extract the client signal from the received signal transmission frame, a client-side interface unit configured to transmit the extracted client signal to a client transmission path by using a generated clock, based on frequency adjustment information of the client signal included in the signal transmission frame, a protection-line-side memory configured to store the frequency adjustment information of the client signal included in the signal transmission frame received from the protection line, and a switch controller configured to control to generate a clock by using the frequency adjustment information of the client signal stored in the protection-line-side memory when the signal transmission frame fails to be received from the working line.
