Hi all,<br><br>I wish to come back on the discussion concerning a "more accurate ECN feedback".<br>I utterly support the following draft draft-kuehlewind-tcpm-accurate-ecn-option and <span class=""></span>the idea that this binary signal is not enough to clearly take an optimal decision concerning the sending rate. <br>
<br>Two years ago, we drove a study to illustrate that the use of a simple ECN counter might open the door to several schemes and methods allowing to better assess the level of congestion and thus, react to losses in a consistent way. See : <span class="">Diana, Rémi</span> and <span class="">Lochin, Emmanuel</span> <i>ECN verbose mode: a statistical method for network path congestion estimation.</i> (2011) Computer Networks, vol. 55 (n° 10). pp. 2380-2391. ISSN 1389-1286 available here : <a href="http://oatao.univ-toulouse.fr/4779/">http://oatao.univ-toulouse.fr/4779/</a><br>
<br>Enhancing ECN feedback would greatly help us to collect statistical information in order to optimize the TCP reaction to this signal.<br><br>Emmanuel<br><br><br><div class="gmail_extra"><br><br><div class="gmail_quote">

</div>While I really enjoy the technical ideas in this discussion, I am somehow concerned about the tone here... I think the community must really understand that *burglary* is not at all an appropriate approach for getting the beloved bits in the TCP header. Instead, quite obviously, the right thing to do is bribery of the TCPM chairs ;)<br>
