I happen to know of at least one company that offers this kind of middle box and also ships CoDel and BLUE (I think it was). Those are DPI boxes, though (*shudder*) -- and I think the price tag is quite a bit more than $10k... :/ -Toke _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
