List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 30 Jun 2023 15:46:48 -0000 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. https://tma.ifip.org/2023/wp-content/uploads/sites/12/2023/06/tma2023-final= 37.pdf 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. --=20 Podcast: https://www.linkedin.com/feed/update/urn:li:activity:7058793910227= 111937/ Dave T=C3=A4ht CSO, LibreQos
