This is where a two-box solution might work better, running something like the wndr as an internal router/AP, and using a separate box for the high-speed AQM for the edge routing? A dual-port GigE platform seems like it would be easier to find (or build via mini-itx). I'm nearly certain that something like a dual- or quad-codre i.MX6 at >1GHz could do the work, but those just aren't available in a "home router" package, which is the killer. The fact that the home routers are commodity products, and built to cost with a very narrow feature set makes it exceedingly difficult to locate platforms that are viable for experimentation. Basically, we need a high-performance-networking version of a Raspberry Pi. -Aaron --90e6ba613a1e072d5f04f5aab37c Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable

I would say that it would be desireable to have a device that is available = world-wide, that doesn't have a lot of different versions of the hardwa= re that are different.

I also think that it'll be very hard to find a box that is decently pri= ced that also will do gig speeds *and* will do AQM, since most home gateway= s that are this quick has hardware acceleration that in turn requires vendo= r proprietary kernels to drive the hardware.

So if you want to fulfil both, I think we need two platforms. A CPU based p= latform that is quick enough to do AQM in and CPU forwarding in gig speeds = will most likely have to be Intel based and cost 300 USD or more.
