It has an RFC at <a href="https://datatracker.ietf.org/doc/rfc9330/" rel="noreferrer" target="_blank">https://datatracker.ietf.org/doc/rfc9330/</a><br>
<br>
I read it as a way to rapidly find the available bandwidth without the
TCP "sawtooth". The paper cites fc_codel and research based on it.<br>
<br>
I suspect My Smarter Colleagues know more (;-))<br>

Is L4S a solution to bufferbloat? I have read that gamers are happy with it.<br>

Sorry, I read it here, in Spanish:<br>
