(bak presh-&r) (n.)
Also referred to as backpressure flow control
, a condition wherein a switch
causes a transmitting device to hold off on sending data packets
until the switch s bottleneck
has been eliminated (i.e., when its buffers
holding data have been emptied). In order to create backpressure, the switch either broadcasts false collision detection
signals or sends packets back to the originating device if the buffer is full.
