Prior to BQL, NO aqm or FQ worked right at line rate. I have kept hoping some paper would examine the difference in latency due to BQL for quite some time now... if it wasn't for the BQL breakthrough: https://lists.bufferbloat.net/pipermail/bloat/2011-November/000726.html The bufferbloat.net project would have folded up shop and quit that year, if BQL hadn't arrived, as our initial focus on fixing wifi wasn't working out. The BQL concept and implementation are delightfully simple and fast enough to run at interrupt cleanup time. http://lwn.net/Articles/454390/ And the results, spectacular, particularly on hosts with TSO or GSO enabled, and at a wide range of rates, particularly high ones. 2) The same person that did Data Center TCP went off to do pfabric. I don't see that in here. 3) Also HFSC seems to be widely used, in the DSL market in particular, and is not in here. 4) Numerous other nits. I do hope further input from the community is solicited for a 1.1, and I'd love it if it were available as a wiki or html document one day for easier browsing/decoding/searching from the Internet. > > On 21. juli 2014, at 11:17, David Ros wrote: > > Hi all, > > The following paper may be of interest to ICCRGers: > > "Reducing Internet Latency: A Survey of Techniques and their Merits" > > available here: > http://riteproject.files.wordpress.com/2014/07/latency_preprint-31.pdf > > This is a much-extended version (understatement) of a position paper of o= urs > that was presented in last year's ISOC workshop on Internet latency. > > It's currently under submission to a journal, so this preprint will be > slightly amended for the eventual journal version that in principle shoul= d > be available in a few months.
