[Bloat] Beyond Bufferbloat: End-to-End Congestion Control Cannot Avoid Latency Spikes

[Bjørn Ivar Teigen]

Hi everyone,

I've recently published a paper on Arxiv which is relevant to the
Bufferbloat problem. I hope it will be helpful in convincing AQM doubters.
Discussions at the recent IAB workshop inspired me to write a detailed
argument for why end-to-end methods cannot avoid latency spikes. I couldn't
find this argument in the literature.

Here is the Arxiv link: https://arxiv.org/abs/2111.00488

A direct consequence is that we need AQMs at all points in the internet
where congestion is likely to happen, even for short periods, to mitigate
the impact of latency spikes. Here I am assuming we ultimately want an
Internet without lag-spikes, not just low latency on average.

Hope you find this interesting!
