| 1. A flow control method comprising:
transmitting a first plurality of packets from a transmitting node to a receiving node at an initial packet rate;
transmitting a second plurality of packets from said transmitting node to said receiving node at a congested packet rate less
than said initial packet rate in response to a signal from said receiving node representative of a congested condition at
said receiving node; and
controlling a length of an inter-packet gap disposed between at least two of said second plurality of packets to change said
initial packet rate to said congested packet rate;
wherein said transmitting node comprises an Advanced Telecommunications Computing Architecture (ATCA) blade of an ATCA chassis
and said receiving node comprises a switch of a backplane of said ATCA chassis, and wherein each of said first and second
plurality of packets complies with an Ethernet communication protocol; and
wherein said length of said inter-packet gap is selected in response to a portion of said signal representative of a severity
of said congestion condition.
