Hi,

When watching the $SUBJECT presentation I noticed that 100% BBR is always optimal, when the buffer was ½ BDP. Is that so?

Also have you studied smaller buffers and/or more data points in the 0 BDP range? I hope that these smaller buffers will become typical, also addressing bufferbloat to some extent.

We also have some related results in http://ppv.elte.hu/buffer-sizing/ for the smaller buffer size ranges with BBRv2.

Maybe this paper on buffer sizing is also somewhat relevant: https://arxiv.org/abs/2109.11693

Cheers,
Sz.
