Transmission device, transmission method and computer program

摘要

Flow control can be performed for every piece of end-to-end traffic. A transmission device includes a reception buffer which temporarily accumulates received transmission unit data, a signal generation section configured to generate a control signal for instructing to stop transmission of transmission unit data by designating another transmission device serving as an end point of a transmission side for traffic of the transmission unit data to be received by its own device as a transmission destination when an amount of accumulation in the reception buffer has exceeded a predetermined upper-limit threshold value, and a transmission section configured to transmit the control signal.

主权项

1. A transmission device, comprising:
a computing device, which includes processing device and a memory, the memory having stored therein computer code configured to cause the computing device, upon execution of the computer code by the processing device, to operate as:
a reception buffer which temporarily accumulates received transmission unit data;a signal generation section which, upon a determination that an amount of accumulation in the reception buffer has exceeded a predetermined upper-limit threshold value, generates a control signal that instructs an other transmission device to stop transmission of transmission unit data by designating, for only traffic of the transmission unit data for which the transmission device serves as an end point of a reception side among a plurality of pieces of traffic accommodated in a physical link, all transmission devices serving as end points of a transmission side in the traffic as transmission destinations, and does not instruct an intermediate transmission device disposed between the transmission device and the other transmission device to stop transmission; anda transmission section which transmits the control signal to the other transmission device.
