Abstract
A flow control enabled Ethernet switch that applies backpressure to input ports that attempt to transmit a data packet to a busy destination port. The backpressure is a phantom packet that activates to abort transmission of the data packet. When the destination port is available, the phantom packets control retransmission, permitting standard retransmission of the data packet. The switch may include prioritization mechanisms to use when awarding priority to a port having backpressure applied.
