There was a whole workshop on it a couple of years ago; not sure if = it concluded anything: http://buffer-workshop.stanford.edu/program/ But really, asking about buffer sizing is missing the point; if you have = static buffers with no other management (like AQM and FQ) you're most = likely already doing it wrong... :) -Toke _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
