Aside from admiration for the scope and breadth of the analysis (particuarly chapter 8 forward - I'm rather dubious about most classification teniques)... My principal question on all that work... All the models/sims were over ethernet and assumed fairly high bandwidth connectivity. I would really like to take a recent model showing 'fairness' of a network protocol such as LEDBAT, and apply it to a set of wireless connections that exhibiting the kinds of behaviors we've been seeing (exorbitant buffering and retries) The results should be... interesting. Perhaps the models used here - or the real implementation(s) - can be fed buffer sizes in excess of 1064, and delays in excess of 2 seconds ... over fairly long paths.
