I am curious as to what extent awareness and mitigations for the bufferbloat problem(s) have made it into enterprise gear? I'm aware of efforts in P4 for fq_codel, fq_codel being the default for most linuxes now,of the AFD algorithm in cisco's gear, comcast's fulll rollout of DOCSIS-PIE on their CMTSes ( https://arxiv.org/pdf/2107.13968.pdf ) during the covid crisis, experiments with L4S/DCTCP and SCE in the IETF, middleboxes such as libreqos and preseem, other server fixes like the adoption of TCP_NOTSENT_LOWWAT in apache traffic server recently...
In particular I'd like to learn of any offload efforts or improvements being deployed at head-ends of any sort, and at overcongested interconnects. I'd also love to learn of a CISCO AFD deployment story.
Is anyone tracking ecn usage, also?
