Abstract
A network switch having switch ports for communication of data packets with respective computer network nodes according to CSMA/CD protocol that resets a retry counter within any one of the respective switch ports if backpressure is asserted by that port. The resetting of the retry counter within a port after assertion of backpressure affords the port a greater probability of winning collision mediation under the CSMA/CD protocol, thus more quickly relieving congestion which may occur in the network switch.
