I see that L4S is not really solving everything (I read about issues with
Wi-Fi), although it seems to be a step in the right direction, to be
improved, let's hope.

At least, Nokia is implementing it in its network gear (for mobile
operators), so the bufferbloat problem is somehow acknowledged by industry,
at least initially or partially.

I have seen two consecutive RFCs to 9330:
https://www.rfc-editor.org/info/rfc9331
https://www.rfc-editor.org/info/rfc9332

I suspect that optimal results require the bufferbloat to be addressed not
only at network layer (IP), but also with some pipelining or cross-layering
at link level (Ethernet, Wi-Fi or any other link technology, such as 5G,
SATCOM, VHF...)

It has an RFC at https://datatracker.ietf.org/doc/rfc9330/

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.

I suspect My Smarter Colleagues know more (;-))

Let's split this thread and use this message to continue the discussion of L4S. Thanks
