I actually tried my hand at finding something better for my master's thesis and came across something called a Markov-Modulated Poisson Process (MMPP/D/1 queue)[0]. It looked promising, but unfortunately I failed to make it produce any useful predictions. Most likely this was as much a result of my own failings as a queueing theorist as it was the fault of the model (I was in way over my head by the time I got to that model); so I figured I'd mention it here in case anyone more qualified would have any opinion on it. I did manage to get the Linux kernel to produce queueing behaviour that resembled that of a standard M/M/1 queue (if you squint a bit); all you have to do is to use a traffic generator that emits packets with the distribution the model assumes... :) The full thesis is still available[1] for the perusal of morbidly curious. -Toke [0] https://www.sciencedirect.com/science/article/abs/pii/016653169390035S [1] https://rucforsk.ruc.dk/ws/files/57613884/thesis-final.pdf _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
