I don't quite follow. What is the behavior is some packets of a window are lost, retransmission of the full window? Retransmission of the delta? In any event, unless the window is shrunk and/or delays before retries are being applied, I don't see anything here that actually reduces the sending rate when loss is detected, which is required.
