This paper (using a fluid model for bbrv1 an bbrv2), at least, includes the RED AQM. Also, right there, in fig 1, is slow start doing damage, not successfully modeled. Aside from those nits, the paper gets better from there. https://arxiv.org/pdf/2208.10103.pdf --=20 FQ World Domination pending: https://blog.cerowrt.org/post/state_of_fq_code= l/ Dave T=C3=A4ht CEO, TekLibre, LLC
