LGTM, so I approved it. I've reached the "bufferboat" and started to = settle in, met Rod and Pete=E2=80=A6 I brought a Pi Zero W with me as a basic Linux test environment, but I = need to find a mini to macro HDMI adapter to make it work with this TV. = Pete says he'll look for one to bring over tomorrow. So now we probably have *two* working middlebox implementations, using = different approaches, but we need a visualisation tool (hi Pete) and = some sort of working TCP that uses it (whether using the sqrt rule or = the 1/n rule, doesn't really matter - but preferably examples of both). = For the latter, we can temporarily get away with inferring stuff from = standard tcptrace. If there's a working implementation of AccECN for = the feedback path, we might as well use that for demo purposes. I want to be able to demonstrate SCE actually working as designed, in a = single-queue implementation, to answer the main argument that some of = the L4S folks have latched onto. But I don't know how soon we'll be = able to manage that. - Jonathan Morton
