Has anyone ported it to bbrv2 yet? We haven't attempted to do anything with BBR yet, instead trusting that = any results using conventional AQM and/or L4S will translate reasonably = easily. Instead we're focusing on conventional window-based algorithms, = getting the reference qdiscs right, and pointing out enough flaws in L4S = so that it stops being an obstacle to IETF progress. We *have* got a big vote of confidence in the form of funding from both = RIPE and NGI Pointer. That gives us time and freedom to work on SCE = without too many unnecessary distractions. One of the things we're = doing with that is building a decent test harness. - Jonathan Morton=
