A talk describing Google’s new TCP congestion control algorithm, BBR, is now online. Such a beautiful and simple solution to a long standing problem. This one of those situations when you have to wonder why this wasn’t done before. On a related note, it’s interesting how BBR separates the retransmission and congestion control (rate) logic.…

History of SDN-like approaches

I stumbled across an interesting paper called The road to SDN: an intellectual history of programmable networks (ACM DL link) this morning. It’s good to place current trends in historical context especially while keeping RFC 1925 Rule 11 in mind. The concept of active networking is particularly intriguing to me. Could eBPF be the instruction…
