Do we share the same definition of cross traffic? The testbed consists of fifo, codel, and fq_codel queues, against 1-2 tcp flows, against a p2p videoconferencing flow. I am sometimes just as subject to confirmation bias as the next guy, and in re-reading this this morning I would have liked it if they had cited rfc8290, and extended their tests to use a bigger BDP for the fifo as well as tested web PLT. a shorter RTT would also be interesting in the case of a ptp app such as this. An exciting part to me remains in exploring the videoconferencing QoE technique they discuss (Brisque) which I haven´t found sources for yet... > > > > > https://tma.ifip.org/2023/wp-content/uploads/sites/12/2023/06/tma2023-final37.pdf > > > > Naturally fq_codel shines.
