Quality jitter metrics have long been lacking on the internet. https://link.springer.com/chapter/10.1007/978-3-030-98785-5_7 "We discovered a set of features in jitter and jitter dispersion =E2=80=94a jitter-derived time series we define in this paper=E2=80=94time series that are characteristic of periods of congestion. We leverage these concepts to create a jitter-based congestion inference framework that we call Jitterbug. We apply Jitterbug=E2=80=99s capabilities to a wide rang= e of traffic scenarios and discover that Jitterbug can correctly identify both recurrent and one-off congestion events. We validate Jitterbug inferences against state-of-the-art autocorrelation-based inferences of recurrent congestion. We find that the two approaches have strong congruity in their inferences, but Jitterbug holds promise for detecting one-off as well as recurrent congestion." It looks very promising. Is the code anywhere? Is the talk up? ... and where do you plan to go next with it? Are any other groups beginning to leverage it? > Ricky > --=20 Still trying to fix the internet on a too-small budget: https://www.patreon.com/dtaht Dave T=C3=A4ht CEO, TekLibre, LLC
