Abstract:
1. A packet handing process for a retransmit controller coupled to a pointer memory, a host memory, a media access controller (MAC) having an input and an output, a block buffer coupled to said MAC output, and an ACK/Retransmit controller receiving acknowledgements for packets in said block buffer, the process having the steps: a first step of moving a plurality of packets identified by said pointer memory from said host memory to said MAC, said MAC forming frames and transferring said frames to said block buffer; a second step of transmitting said frames in said block buffer and sending an acknowledgement request; a third step of receiving acknowledgement of received frames and identifying whether un-acknowledged frames are present in said block buffer; a forth step of removing said acknowledged frames from said block buffer and retransmitting said un-acknowledged frames from said block buffer with an associated acknowledgement request, repeating said fourth step until no said unacknowledged frames remain.
