I'm perfectly happy qualcomm found a way to combine the packet classification technology acquired from from bigfoot with the scheduling and aqm stuff given away here, in a business model that seems to be working. fq_codel made it into wireless-backports because of them, and now we're seeing the downstream effects when made easily available in the older kernels common in the embedded world, and when salesreps have something to push. they also did up a nice gui. It's really neat they don't mention bufferbloat, ever, anywhere, and as a positive differentiator, that too, appears to be working. That's sort of why I keep talking about the make-wifi-fast concept as - as a mission - it has more positive connotations, than "if we don't fix bufferbloat the net's gonna die". ok, bloat fixes are being deployed everywhere along the edge. and everybody wants to make-wifi-fast. some of the methods for doing so (wider channels, louder radios) are more hurtful than the ones I'd like to see getting done, like: per station queues maximizing aggregation in txops multi-user mimo detecting interference eliminating reorder buffers reducing retries reducing overly agressive attempts at avoiding packet loss sorting on aggregate dequeue applying fq_codel on a per station basis streamboost doesn't - as currently designed - apply to wifi. fq_codel only barely does at the layer of stack it's in now, and these other factors predominate. > It cheers me up that *codel is about to be picked up by the vendors, > but not when customers are tricked to pay extra for SuperBoostNow [tm] > or DoMeQuick [tm]... Well, there has been a lot of snake oil prior to now. Hopefully the press will start creating more useful benchmarks. I did bother to reply to that post. Me, I'd like benchmarks... http://forums.smallnetbuilder.com/showthread.php?p=3D101052&posted=3D1#post= 101052 one takeaway from that review was... the next job facing us is to make-wifi-fast again, in increasingly crowded = radio conditions, in a world where people insist on running HD video over it at t= he same time expecting decent videoconferencing and (at least my case) mosh experiences.... > -- > Maciej > > On Fri, Jan 24, 2014 at 1:06 PM, Aaron Wood wrote: >> It would be interesting to see what streamboost gains on top of just >> fq_codel.
