To my surprise Peter Lothberg the Internet Genius who delivered a 40G interconnection to his mother, and whose "requirements" Cisco bear in mind when designing routers, has replied to my email about it with some details for us:

Yes..

It is 39.813120 Gbit/s It's OC768 with POS (cisco HDLC) encoding.

RX LOS Threshold = -15.00 dBm

> Does your mum now enjoy the same upload speed or is that more restricted?

It is 40G to the house, the PC itself has a 10GE interface and we
benchamrked the PC at some 8Gbit/s.

The limitation is usally the server on the other end.

> Could/would you give us a very brief description of the technology concept?

Mother lives 410Km out in the boonies, so It's a sigle optical shot
on a wavelengt from the garagae to a router at a major IP pop/HUB in
Stockholm. Do traceroute to 192.108.195.250.

This is all of the shelf stuff, all router stuff and optics are
cisco CRS1.

I would like to se people build computers to the upcoming 100Gig
Ethernet standard.

So .. there you have it ... she really does have a 40G internet connextion ... but the PC can only handle 8G looooooooooooooooooooooooooooooooooooooooooool :D:D:D:D:D

Still gobsmacked the "third most important man in optical networking" replied to my email ;)

I'm gobsmacked he replied frankly - what a nice chap.

It looks like she has 40G in each direction although only 8 is useable because the computer can't cope ... and "only" has a 10G NIC in any case :D :D :D ...

Of course ... she can get her friends round and have a fab LAN party playing online blackjack with absolutely no lag ...

I think ... it helps if your son is the worlds "third most important optical networking guru" and can, effectively, get the router the other end plugged straight into an internet backbone.

I wonder if he wants to adopt a stray Englishman?

Dammnn!!

Nice man!!!
I thought this thread was reporting on the fact... but you actually have a conversation with the man!
w00t!! Nice!
What a cool dude! :)

If I had that internet connection, I would use part of it (if possible) to relay traffic for the Tor network.
That, and to seed torrents of works of art that their copyrights have expired.
Like the movies Darwin made.
The mp3s Mozart recorded.

Oh, and I would definitely offer up bandwidth for TBCS.

That's hilarious. I wonder how much data she transfers in a given month.
1GB? 5GB?
And I'd reckon most of it would be pictures/Ads/clips from pages she's visited.

Very cool!

Indeed I was rather surprised he replied. She only reads the local newspaper online so I think she is probably using a few Megabytes per month lol.

He did say something at the bottom aimed at us guys and gals particularly:

"I would like to se people build computers to the upcoming 100Gig Ethernet standard."

Now there is a mod-project: Build something that can take in and handle that dataflow.

i want to know what hard drive has that sort of writing speed, it would take one hell of a drive to keep up with downloading at 40GB/s

its 40Gbit so thats only about 3GB/s

Indeed .. and therein lays much confusion: bits and bytes. It's actually about 5GB/S as there are 8 bits in a byte :)

feed it, and when its big enough, skin it, and make a stew, with the skin, use it for a mod,

I think the quote was she can download an entire DVD movie in under 2 seconds or watch 1,650 HDTV channels at the same time. But yes HDD Upload in 2 minutes sir, no problem :D
