Linux 6.2 Begins Making Preparations For 800 Gbps Networking

[NobodyXu]

Scandinavian researcher have set a new world record by transmitting (citing) "1.84 Pbit s–1 over a 37-core, 7.9-km-long fibre using 223 wavelength channels derived from a single microcomb ring resonator" - see https://www.nature.com/articles/s41566-022-01082-z

That new world record is for data center.
It is unlikely for a single computer to process that much data anyway, it doesn't make sense for your laptop/desktop machine at home to use a 1.84PB fiber.

And what makes you think people would actually need that?
Even 5G is a bit too much since 4G is enough, not to mention 5G is harder and more expensive to deploy due to its fragile signal and more expensive, most people just use their mobile to watch youtube or browsing, do they really need 4G?

IMHO if Google thinks about establish Lazy RCU to save the last milliwatt on a CPU idleling the network components manufacturers, hard and software developers may also rethink the way we do networking in LANs and WANs in future and should focus on to become an all optical network not only for LAN and WAN.

Lazy RCU is very useful for laptop/desktop machine since most of the time your machine is not doing a lot of work.
Many cores in the CPU is probably idle with a few active, handling the browser, some network operations, etc.

Also main or serverboards could receive a new design in case of connecting to the network. It is possible that the work Intel has already done in this area will finally bear fruit.
