Internet Data Transmission Record Shattered by Danish Researchers

[medi01]

Capitalism is all for data caps

Never had data caps (except on mobile phone, where it simply drops speed when the cap is reached).

And I've used:

14.4 =. 56k modems
ISDN
DSL
Cable

There will be no internet with hard disk, SSD maxsimum speed.
Cant even get USB 1-2 port speed.

Not over long distances and not very soon. But there are many 100 and even 400Gbps links in data centers. Plus, what you are talking about is instant disk mirroring over distance, good luck with that.

USB2.0 speeds can reach 480Mbps at L1 but baud rate drops to ~20MB/s in sustained transfers due to overhead. And 1Gbps link can get you 20MB/s with no sweat at all.

Now what kind of router and switches technologies needs to be build in order to transmit this kind of speed over the Internets?

Insane ones! Especially if you want switching at wire speeds. Just imagine this - even latest $1000 CPU can only get around 50-60Gbps of RAM bandwidth, and only from insanely tuned (and just as expensive) RAM sticks.
And now imagine if you have to switch 100 ports of 100Gbps each! Puts things into perspective, no?

It is weird that people living in the so called first world countries still have data caps, while people in 3rd world countries don't, then you remember there is a place called the United States

I'm in the US and I haven't had a data cap as long as I can remember from when I had dial up in the 90s. The options where I am now are Comcast (offers gig over fiber) and Verizon (also offers gig over fiber) neither has a data cap.

My phone has a 6gb data cap but offers unlimited plans as well. I don't need that so I'm not going to pay for it and I don't use all my data so it keeps rolling over till I have a massive pool of it.

Turns out the legend was true , RGB does increase your internet connection

Ironically, yes.

Wow. That’s a long time for a cpu OC record!!

 

[TheLostSwede]

I just threw in some very approximate figure. My FTTH connection reaches 180/25 Mbps with the exchange (or whatever it's called) some 20 km away. Most likely it's an all passive network with no amplifiers in between, just splitters.

I'm not familiar with the latest development in copper technology, I still think that 100 Mbps over one kilometre is close to the limit, or over the limit, of any DSL. Am I wrong?

Don't forget that cable TV networks run over copper as well, so DOCSIS networks can achieve much higher speeds than xDSL.

Yep. On a phone with 1 bar service….sigh.

The next thing I'm wondering about is what sort of CPU power and network adapter(s) one needs to maintain such a high connection speed.

 

[CapNemo72]

Well, for starters, those chips are not for us at home, they are for the telecom companies to bring us high-speed internet.
By using only one chip, they can pack more in the same space and (just maybe) make it cheaper.

I remember the times when HDDs were too slow for a 1Gbit fiber connection.

Todays SSDs NVMe are around 5000MBs (some less, some more), so you would need a 40Gbit fiber connection to hit their speed.
Folks that have 10Gbits connections are already bottlenecked by SATA SSDs or the ones that are around 1000Mbs.
Imagine your download speed is faster than your SSD. Funny times.

Of course, companies are already using speeds past 100Gbit (and several of them), especially to connect to their data centers.

There is a lot of HW offloading done in the NIC itself, but main thing to remember here is that this is (for the time being) a data center thing. No ISP would invest into something similar for their end-users.

I have to admit that I work for a ISP based Tel co in Canada and these would be great for Cross Province/Country Fibre for the foundation of fibre networks.

Distances are the real issue here. 100Gbps would be a beast for backbone but given the sheer size of countries like Canada it's simply not possible as of now. Not unless major investments are done for signal regeneration.

 

[Wirko]

Sources (Tom's and others) say that the data was sent over 37 fibres, not a single fibre. However, just one laser and one optical chip did all the work at the transmitting end. The optical bandwidth was, hold your breath, about 8 terahertz (infrared light between 188 and 196 THz).

No word about energy per bit transmitted but it must have been record low.

Not sure what you mean. Literally, I have a cheap 1Gbps/s Internet pipe right now.

And now imagine if you have to switch 100 ports of 100Gbps each! Puts things into perspective, no?

This is nothing fancy. Just like Carrier type Router and Switches, they are using a blade system with multiple Processors assigned to each port, each blade, etc. Expensive af, but very much doable.

It means they'll be able to burn through their monthly data cap in 8 minutes instead of 14.

Haha haaaa, cost also follows ...#

Protocols restructuring, and we can not escape that!!!
