One of my readers asked for my opinion about the provocative “It’s Time to Replace TCP in the Datacenter” article by prof. John Ousterhout. I started reading it, found too many things that didn’t make sense, and decided to ignore it as another attempt of a proverbial physicist solving hard problems in someone else’s field.
However, pointers to that article kept popping up, and I eventually realized it was a position paper in a long-term process that included conference talks, interviews and keynote speeches, so I decided to take another look at the technical details.
