[Bloat] Instant Messaging Meets Video Conferencing: Studying the Performance of IM Video Calls

[Dave Taht]

This paper does a really good job of measuring the impacts of tcp
cross traffic, including BBRv2, against the videoconferencing
subsystems in signal, telegram, and whatsapp.

Naturally fq_codel shines. The paper also introduces a new means of
measuring videoconferenceQoE, called BRISQUE.

About my only kvetch is they didn't try cake, which has a different
shaper, drops less packets, has less collisions, as well as diffserv
support.

Seeing BBRv2 stats and impact was very interesting also.
