Yes, it mentions bufferbloat once, but IMO the subject requires far more than that. I would suggest at least introducing the concept of active queue management, maybe set some of the developments in that closely related field - e.g. RED, SFB, CoDel - on the same timeline with Reno, Vegas, and BIC. Otherwise it's like trying to teach someone driving without mentioning stop signs and traffic lights.
> Larger buffers can lead Reno into a “buffer bloat” state, where the buffer never quite drains. The residual queue occupancy time of this constant lower bound of the queue size is a delay overhead imposed on the entire session.
