Just after a quick read, I fail to see how just decreasing buffer sizes is going to be “better”. Better than just throwing fq_codel on the wireless interface, maybe.

In regards to CoDel and PIE, they say "both of these schemes never consider frame aggregation in the buffer sizing decision.” Isn’t the whole point of CoDel that one doesn’t need to be concerned with buffer size as long as it’s “large enough”?

That’s arm waving that really misrepresents the work without even testing it.

Is there a better place to respond than adding a comment to the article?
