So for those of us who have followed JG's articles about the buffer bloat issue but haven't followed the in-depth technical discussions, is some kind of technical progress overview wrt the Linux kernel available?
E.g. Dave Täht mentions in a comment in the ACM Queue article that byte queue length (BQL) are now in the net->next tree. But what about e.g. AQM algorithms? At some point there was some patch for stochastic fair blue (SFB) for Linux, is there progress on this front? What about the updated RED paper (nRED?), or if the paper is done, an implementation? What else is going on?
