Hi all, since the last IETF we a strong consensus that we should make TCP more robust against packet reordering. I believe as a first step we probably should specify how we can detected and qualify reordering w/ TCP. It gives us the opportunity to learn more about the reordering in the wild and, at the end, any reaction algorithm - whatever it looks like - can benefit from a proper detection/quantification. Moreover I also believe that draft-zimmermann-tcpm-reordering-detection is a good starting point. We just updated the draft in that way that we detected now also reordering > 1 RTT. I know from several people that they are read the draft. Unfortunately, we haven’t received much comments. So, please review the doc and make comments on the document. Thanks Alex
