dear kevin,<br><br>there is a lot of litearture (and results) that you are not aware. only few points:<br><br>1. TCP scalable does not work at all! If you try few connections (few as 3 or 4) you will get starvation of flows. This TCP cannot be used because it does not work not because of efficiency.<br>
2. with TCP you should consider reverse traffic, always, due to the effect on ack, which in turns drive the TCP<br><br>saverio<br><br><div class="gmail_quote">On Thu, Sep 10, 2009 at 4:14 PM, Kevin Mills (comcast) <span dir="ltr"><<a href="mailto:KevinMills@comcast.net">KevinMills@comcast.net</a>></span> wrote:<br>

<br>
On May 20, 2009, I briefed the ICCRG on NIST research related to modeling<br>
and analysis of large distributed systems. Recall that as a challenge<br>
problem we investigated several Internet congestion-control mechanisms<br>
proposed to replace TCP. I attach our conclusions related to the<br>
congestion-control algorithms that we studied. A more-or-less complete draft<br>
of the study (including our supporting data and analysis) is now available<br>
for public review and comments. If you have the time to look this over and<br>
provide feedback, then I would appreciate it. Also, feel free to distribute<br>
this information to others who you think might be interested.<br>
