Is there any study comparing the impact of BBR vs CUBIC on a LEDBAT stream?
I assume it to be equivalent because of LEDBAT's eager backoff, but it'd still be a cool thing to read

The big innovation around these new schedulers is focusing on fairness instead of maximum throughout. For the longest time TCP flow control was judged only by how close it reached to theoretical maximum throughout. So we ended up with extremely aggressive schedulers. The challenge now is to make a scheduler that limits bufferbloat while not surrendering all it's throughout to old school bully schedulers. This is where BRR really innovates
