The method comprises, receiving a frame at a receive port of a networking switch element; determining a transmit port and a virtual lane for routing the frame; asserting a request signal to the transmit port; waiting for an accept signal from the transmit port; determining if an output link on the transmit port is unavailable and if a flow control credit is available for transmitting the frame; sending the frame to the transmit port if the accept signal is asserted; and transmitting the frame on the output link and de-asserting the request signal.
