Abstract
A network device which includes means for receiving data packets over a link, a memory for the packets, means for providing an indication that the occupancy of the memory is less than a first watermark, and means responsive to the indication for providing a sequence of pause frames comprising an alternating sequence of XOFF frames defining a very long cessation of the sending of packets and XON frames defining substantially zero cessation of the sending of packets. The means for providing the pause frames is responsive to the increase of the occupancy of the memory above a selected watermark to cease the provision of the sequence of pause frames.
