I'm really impressed. I'd have probably heard about it if they'd mentioned bufferbloat once :/. The graphs comparing their performance to arista's are far, far, far too small to read. You can certainly see a huge improvement on mice in this paper. is there a better copy of this paper around? What's the cheapest form of this switch I can buy? (or beg, borrow, or steal?) I do need a 10GigE-40GigE capable switch in the lab, and BOY oh boy oh boy would I love to test this one.
