I think most of us would be relieved if competent single-queue AQMs became ubiquitous. It doesn't have to be Cake everywhere, just *something* unambiguously better than a dumb FIFO - and that's a rather low bar to clear. Now, when you have a 6000-channel router, I expect it starts with some very simple and fast device to direct packets in *approximately* the right direction, where some other piece of hardware deals with some subset of the total port count. Let's say you have a 1Gbps+ link to a 64-line cluster. Immediately the problem of providing FQ on each of those lines is more tractable; you can give each one 1024 queues and AQMs, the same as fq_codel, for a quite manageable total of 65536, and it's not so hard to build hardware that can keep up with 1Gbps traffic these days. - Jonathan Morton _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
