Admittedly the version as planned to be implemented in cable modems is so very different as for me to despair of getting comparable results, but... Now that it is apparently stable, and cero seems stable... I'd appreciate some results using it (with the default pie target of 20ms and with a target of 5ms) with tests l= ike rich's new stuff, and rrul... I'm particularly interested in DSL results. pie was extensively simulated using ns2 models that I disagree with on many points, but does appear to work fairly well for simple models of traff= ic, which was what it was mostly tested against. On my todo list is to try combining drr + pie or qfq + pie. pie target 20ms: root@comcast-gw:~# ./speedtest.sh Testing against netperf.richb-hanover.com while pinging gstatic.com (60 seconds in each direction) ............................................................
