That depends on your definition of better, I guess. Typically = flow-fair queuing seems to be what most people prefer (unless an = application either does not respond to AQM signals or open an excessive = amount of individual flows flow-fair queueing effectively treats most = traffic sources equal, pretty much what people seem to want, add to this = a bit of classification to exempt e.g. VOIP traffic from only getting = its flow-fair share of the bandwidth and the whole thing also works = reasonably well with slow links). People suffering from unruly = applications (like mis-configured? bit-torrent clients or recently = windows update) often ask for per-application fairness, but that is not = something a router will ever be able to deliver in my opinion; the = closest we get to this would be fairnes by internal or external end-IP = addresses. Luckily cake offers just these modes =E2=80=9Cdsthost=E2=80=9D,= =E2=80=9Csrchost=E2=80=9D and even better offers a combination modes = that will on a first level attempt per host-IP fairness and within each = host IP also per-flow fairness (=E2=80=9Cdual-srchost=E2=80=9D and = =E2=80=9Cdual-dsthost=E2=80=9D, and even =E2=80=9Ctriple-isolate=E2=80=9D = which systematically might be better called =E2=80=9Cdual-srchost-dsthost=E2= =80=9D since it offers fist level fairness based on an under-documented = mix of src and dst addresses, but I digress). Please note that on a = typical homerouter, due to NAT, all the IP addressed based fairness = modes will not work for IPv4 on the wan interface, IPv6 traffic should = be fine, but IPv4 basically degrades into a computationally more = intensive version of flow-fairness (as after NAT cake only sees the = routers external IP for all internal hosts). This might have been more = than you wanted to know=E2=80=A6 Best Regards Sebastian >=20 > netperfrunner looks very useful.
