If we don't, = can we measure it? Anyone know of devices shipping or being designed = that does FQ of some kind? Linux and OSX end hosts now routinely run fq_codel by default. That's = an awfully large installed base, both of FQ and of Codel. It is perhaps = worth observing that these are rarely bottlenecks for Internet paths, = though they might be for LAN paths. The IQrouter is probably the best example of a commercial middlebox that = does FQ, in this case using Cake. I hear that it is now being sold in = re-branded form to certain large ISPs, but I could be wrong about that. = I've CC'd Jonathan Foulkes for comment. There's also a large French ISP which has done fq_codel on its last mile = for quite some time. - Jonathan Morton=
