[Bloat] [NNagain] The Verge: The quiet plan to make the internet feel faster

[Sebastian Moeller]

Hi Frantisek,

steering this to the bloat list, as I have a hunch my response might not be appropriate for the wide audience in NNagain even though this can have NN ramifications.

Unlikely, as that would e.g. violate EU directive 2015/2120 too blatantly. My take is more subtle, L4S is essentially a technique that only works well for short RTTs and the end game is to make datacenter space inside eyeball-ISPs much more desirable and hence yielding higher prices... L4S effectively increases TCPs existing RTT bias* and hence makes long range L4S connections undesirable/under-performing, and that implies that content providers that want to use L4S will need to get their servers/CDNs close to the eye-balls. But hey, I would love to be wrong and ISPs jus do this out of the goodness of their hearts... (only then I would politely ask the to deploy a flow queueing AQM instead of DualQ, as that in one swoop will solve a ship-load of L4S problems).

Regards
	Sebastian


*) L4S argues that this is not an increase, but that due to removing traditional TCP's excess queueing it just reveals TCPs inherent RTT bias; IMHO that is a bull shit argument since the root cause is not important, what matters is that with L4S RTT bias becomes measurably worse.


P.S.: I think my mail provider marks outgoing mails with too many links as SPAM, so I need to make the URLs invisible, and I believe replacing the t's in h t t p with plus signs does the trick...
