China launches world’s fastest internet with 1.2 terabit per second link, can transmit 150 4K movies a second::China is claiming that they now have the world's fastest internet. Their new network transmits 1.2 terabits per second. That's over 1200 gigabits, per second. At this speed, the network will be able to send 150 4K movies in less than a second. Furthermore, it can send all of Netflix's global content

This is moat likely a core/main/back bone switch that feeds many smaller switches. Its not outside the norm, we're seeing 400gb and 800gb switches that are easily able to push that much bandwidth out a single port. 1.2tb or 1.6tb switches are the next logical step. You'll only find these switches in massive datacenters or for server clusters like for AI or high performance computing

My campus is working on upgrading our redunant 100gb ISP connections to 400gb next summer, so not necessarily just for HPC/AI/'massive datacenter'.

Granted,

A) our 100gb edge routers are reaching end of life

B) a LOT of grant proposals will be able to put down "400gb uplink on our campus", which helps land research money

C) The new routers will probably run for 5-6 years before we start scheduling an upgrade, so its considered money well spent on future proofing.

Our actual bandwidth utilization normally peaks at like 22gbps (every now and then we do see it get closer to 75gbps, but that's perfsonar running tests to/from other institutions).

Thank you for dropping some savory knowledge!

It has to be. There’s nothing in anyone’s house that can use anything remotely approaching that much bandwidth.
