It was introduced into OpenWrt in May 2012 and made fq_codel the default queue discipline in April 2013, at least in trunk (I don't use standard releases, so I'm not sure when those changed). You should get it out-of-the-box for any release later than that. As a result (as well as improved behavior of client software), we generally don't see any problems with bittorrent at Personal Telco nodes anymore. There was a time when I needed to intervene occasionally "to protect the network" from bad behavior (mostly upstream bandwidth saturation and queue filling), but I haven't needed to for so long I've almost forgotten how. We do still discourage bittorrent on public networks, but I'm not sure it's really necessary anymore. Gettys was at a Community Wireless Summit I attended in Barcelona in 2012, and gave a talk about it. -- Russell Senior, President [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
