How to get 10 GB/sec download speed?

Question

i have a friend in japan and he says he is able to download stuff from internet at the speed of 10 GB/sec. And he says in the blink of an eye, the file is already downloaded.

I asked him, how that is possible. He said he has broadband. But I have broadband too, and my download speed is like 1 MB/second. Yet his is 10,000 times faster than that. Where can I get such connection from?

Answer 1

Other answers are close to dead on. Just to add a bit.



In addition to either knowingly (or unknowingly) misinforming you, he is also mixing up MB (GB) with Mb (Gb). Big "B" in either MB or GB means byte or 8 bits. Little "b" in Mb or Gb means bit (1 bit). Two very different things. So 1 GB/s is way faster than 1Gb/s. When someone refers to a Gigabit ethernet router or NIC card, they are talking about Ethernet at 1 Gb/s. When some is referring to USB 2.0 speeds, they are talking about 480 Mb/s.



The internet backbone is generally comprised of Sonet rings in most countries:



T-1 - 1.544 megabits per second (24 DS0 lines) Ave. cost $250.-$500./mo.

T-3 - 43.232 megabits per second (28 T-1s) Ave. cost $4,000.-$16,000./mo.

Sonet OC-3 - 155 megabits per second (100 T-1s) Ave. cost $20,000.-$45,000./mo.

Sonet OC-12 - 622 megabits per second (4 OC3s) no estimated price available

Sonet OC-48 - 2.5 gigabits per seconds (4 OC12s) no estimated price available

Sonet OC-192 - 9.6 gigabits per second (4 OC48s) no estimated price available



So OC-192 is roughly the speed your buddy is referring to (assuming he meant little b, not big B since that would be faster than even an OC-192 backbone ring). These are core internet speeds. The access clouds or "edge" of the internet (e.g. home access in city highrises, subdivisions, etc.) is typically some form of DSL or cable modem. Those speeds are normally on the order of 10 Mb/s and under on the downlink (download) and 1-2 Mb/s on the uplink (you can get better if you pay more, but those are general numbers).

Answer 2

Oc192 Speed

Answer 3

there is a company called AARNET . That provides 1gbper sec or 10 gb per sec.. thats only provided to reserch edu centre and high orgs. so truly there is a 10 gbps internet in oz. go on AARNET.COM and view there service and products. the rest of douchebags which answered know nothing abt computer. must be watchin too much footy aye . if you wanna upsize try tpg nbn internet $230 per month. speed is 100mbps . only selected areas in oz. Thanx

Answer 4

Your friend does not tell the truth. The fastest available is T3 and that's 44.6 MB/sec...a long way from 10GB/sec! Even if you had internet that fast, there are bottlenecks that would prevent you from getting anywhere near actually using all of that available speed.

Answer 5

Hopefully you mean Mbps and not Kbps. The first dial-up modems connected at a higher speed of that at around 28.8 Kbps. What's BSNL? Never heard of it. I know with DSL you can speeds 10 times faster than that with a slow connection.

Answer 6

The internet itself - for non-local (within about 100 miles) connections - runs at about 1mbps or less. If he has a 10GBps internet connection (and some hardware we haven't heard about yet), he could possibly download at 10GBps from his provider. But from the internet? It's the same internet we're using, and even my 120MBps server farm pipe can't get 120MBps downloads.

Answer 7

Some countries have faster internet available than others, its as simple as that. This is due to better infrastructure and higher population density allowing companies to provide fast internet but still be profitable.

Answer 8

your friend is probably confusing his LAN speed for his internet speed. It's not uncommon for someone's LAN speed to be 10gb/s, but that kind of connection is virtually impossible outside of some crazy broadband optical connection (typically reserved for internet backbones)

Answer 9

He doesn't get 10GB/s. 10MB/s MAYBE but certainly not GB.
