Sure, cerowrt's not fully baked, but... I'll GLADLY settle for Linux 3.3 and fq_codel in ALL of openwrt. Which is what has happened. That was/is the main goal of cerowrt - to do valuable research - that could be pushed upstream. And we've done that. I hope to see more distros adopt fq_codel as their default qdisc. AS OF NOW: I'm going to go sleep in a yurt by the water for at least a week, and not think about *anything* computer related. I've got a couple music gigs lined up, but that's it.

Message-ID: Luigi Rizzo and P.

Please see: http://info.iet.unipi.it/~luigi/papers/20120525-sched-fifo.pdf Well worth tossing on your portable devices and reading over the holiday weekend.
