title: Modify the congestion control window value
body: <p>For my research, I would like to manually control the congestion control window size of TCP.</p>
  
  <p>I want to explicitly stop the window from being reduced when segment/ack loss occurs on a test network.</p>
  
  <p>Is this possible at all?</p>
  
  <p>I have been looking into ways of doing this using Python, Netem and Scapy. I have access to both windows and linux (ubuntu 12).</p>
