Internet2 Speed Record Broken

RevKa writes "InternetNews.com has a report of a new Internet2 land-speed record. The old record was nearly cut in half: the two parties, California Institute of Technology (Caltech) and the European Organization for Nuclear Research (CERN), 'transferred 859 gigabytes of data in less than 17 minutes.' InternetNews goes on to say, 'This record speed of 6.63Gbps is equivalent to transferring a full-length DVD movie in four seconds.' Various scientific purposes were mentioned 'as well as commercial applications from entertainment to oil and gas exploration.' The article ended with hardware specs 'S2io's Xframe 10 GbE server adapter, Cisco 7600 Series Routers, Newisys 4300 servers using AMD Opteron processors, Itanium servers and the 64-bit version of Windows Server 2003.'"

how much bandwidth does doom3 need for network gaming?

It is typical of humans to focus primarily on the ways in which new technology can be utilized for 'fun'. Computer games are a particularily ubiquitous example of this phenomenon. Massively networked computers have the potential to become the greatest compound computational device that mankind has ever had access to. If only the proper effort were expended, multiple paralell processing tasks could quite easily be run on this supernetwork. The combined power of this cluster would thus be beneficial to all.

There is slim hope that this will happen, at least in the foreseeable future, human logic being as flawed as it indeed is.

Let us not go down this path

And I quote from the Sacred Book of Trek Episode 23:

The U.S.S. Enterprise is ordered to pick up Ambassador Robert Fox, who is headed to planet Eminiar VII on a diplomatic mission. Upon arriving at the planet, the ship is warned away.

Beaming to the surface with a landing party, Kirk and Spock are met by a Young Woman, Mea 3, who tells them that Eminiar VII has been at war with its neighboring planet, Vendikar, for over 500 years. Mea 3 takes them to the council chambers where they find banks of computers. Eminiar's head council Anan 7 informs them that the two planets have learned to avoid the complete devastation of war because computers are used. When a "hit" is scored by one of the planets, the people declared "dead" willingly walk into antimatter chambers and are vaporized. Anan 7 further tells Kirk that his ship and all the crew aboard her have been declared casualties and will be executed. When Kirk flatly refuses, the landing party members are taken prisoner.

The council members are unable to convince Scotty, in charge of the U.S.S. Enterprise, to lower shields without a direct order from Captain Kirk. Meanwhile, Robert Fox has beamed to Eminiar and is also taken prisoner, marked for death. Kirk and Spock escape and gain the council chambers where they destroy the computers. Kirk tells the council members that they have made this war too easy for themselves and that they will truly experience the horrors of war if they do not learn to make peace first. Ambassador Fox volunteers to stay behind and negotiate a peace between the neighboring planets.

Distributed parallel computing, on the other hand, may be entirely pointless.

It all depends on the relative expense of computation vs bandwidth - not just bandwidth, but bandwidth + all the other hassles, expenses, and technicalities of distributed computing.

So far it's almost always easier (cheaper) to put together the computational resources you need than to put together a network giving you the same capabilities using others' computers.

Station wagon full of backup tapes

Re:Station wagon full of backup tapes

[IWannaBeAnAC]

I don't think so. One DVD in 4 seconds... how many DVD's can you fit in a stationwagon? A few thousand at least (probably 10's of thousands). Each thousand DVD's gives you an hour to drive to the destination to meet the bandwidth requirements.

Except, that I don't think you can drive from CERN to CalTech, even with a few days to do it ;) So, you might actually be right! But they still have a tremendous way to go to exceed the bandwidth of a supertanker....

Re:Station wagon full of backup tapes

[real_smiff]

supertankers are very slow. they have very bad latency. and do these DVDs have cases? :p

Re:Station wagon full of backup tapes

To complete the task you have to load each dvd onto the target computer. I think you are slower now.

Re:Station wagon full of backup tapes

[pinko-rat-bastard]

What Mr. Tanenbaum failed to acknowledge, however, is that the time it takes to *restore* those tapes once they have arrived could well exceed the time it took to transport them. A station wagon full of backup tapes sitting in the parking lot is pretty useless.

Re:Station wagon full of backup tapes

[Rostin]

I think that to be fair, the DVDs would have to be burned at the point of origin and then read at the destination.

Re:Station wagon full of backup tapes

That may be true. However, how long do you think it would take to burn those tens of thousands of DVDs that you're going to transport in the station wagon.

Re:Station wagon full of backup tapes

Yes, except it'll take you 2-3 weeks to

a) Burn all those DVD's
b) copy them back in at the destination

Re:Station wagon full of backup tapes

Yes, but that can be massively parallelized. The total time taken need only be the time to burn & read 1 DVD.

Re:Station wagon full of backup tapes

From a business perspective, think of how this could change distribution. Instead of having to ship DVDs to your local Blockbuster, Blockbuster could have their stores hooked up to the net and just download the DVD's their customers request.

You forgot the time to first write all that data onto the DVDs, and to read it in on the other side. Without those steps, your computer-to-computer data transfer is not complete. Now, how large would the DVD burner farm have to be to beat the transfer rate?

Re:Station wagon full of backup tapes

[zijus]

Hum... Not really "back-up" though. The kind of data which are gonna be produced at CERN in LHC won't be backed up : just too big.

The point of those super fast transfer rates is that probably experiment data will _not_ be stored at CERN at all, just produced and sent straight to storage farmes. Hopefully organisation will be clean enough to avoid more transfere after first storage. The goal beeing : stored where it's gonna be analysed.

I worked a while within the ALICE experiment off-line software section at CERN in 1999-2000. The proportion of problemes are just mind blowing. Some experiment generates so much data at each run that a single extra bit used to store a raw data, immediatly translates into 10th of extra disks required. One run is at max a few seconds. As fare as I remember, ALICE ( A Large Ion Colider Experiment) will generate on it's own 1PB a year. The why of it is: as opposed to colide e-/e+, this experiment will colide nucleus. We could see it as: colide two car side mirors and you get X by-products. But now, colide not the miror only but the whole cars: you get magnitude of order more by-products to observe. The goal , as fare as I rember is to observe some Quark-Gluon-Plasma (QGP), a gas of quark and gluon. It's the fifth state of mater we know about.

Some lads in slashdot thread mentionne p0rn... But just a single peta byte is equivalent of what has been said and written ever by humanity. We'd have to generate a lot of pOrn/mp3s/... to have that much data. Or maybe set up ALIPE ( A Large Intricate P0rn Experiment.)...

Re:Station wagon full of backup tapes

With HD media being so cheap, how about loading up your station wagon with HDs?

Besides, the stationwagon has a far higher total capacity throughput than the server. To get a station wagon's full of data, you'd have to swap the media at the front and back end of the I2 link, too.

Re:Station wagon full of backup tapes

Not quite, here's what Andrew S. Tanenbaum writes in "Computer Networks, Fourth Edition":

[...]A simple calculation will make this point clear. An industry standard Ultrium tape can hold 200 gigabytes. A box of 60 x 60 x 60 cm [approx. 2 x 2 x 2 feet] can hold about 1000 of these tapes, for a total capacity of 200 terabytes, or 1600 terabits (1.6 petabits). A box of tapes can be delivered anywhere in the United States in 24 hours by Federal Express and other companies. The effective bandwidth of this transmission is 1600 terabits/86'400 sec, or 19 Gbps. If the destination is only an hour away by road, the bandwidth is increased to over 400 Gbps. No computer network can even approach this.
[...]
Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.

One DVD in 4 seconds...

And how long does it take you to "burn" it? What's the limit of your local disk system when it comes to pushing data? One (S)ATA disk is, what, 40-50MB/s. Just reading 4GB from one single disk would be ~80 - 100 seconds.

I give the benefit of a dubt and say you've got a RAID system kickin' ass - 10xRAID5 on HIPPI and then some.

Assumming ideal conditions: 10x2x50MB/s = 1000MB/s. Let's be nice and say 1GB/s. (obvously, you'd need hardware ay more expesive than a PC for this). That would be the limit these guys reached - a DVD in four seconds.

OK, we have solved the read speed. Then we got the slowness of burning the DVD's. How many DVD burners would you need, working in parallel on this inherently sequential problem, to be able to create a stationwagon full of this data, reaching the destination on the other side of the globe faster than just using this connection?

Also, even if you *could* do it, would you really be prepared to pay the extra of 10.000 DVD's to RIAA, for you data?

If the MPAA was smart, which they usually aren't, they would support this with their minds on movie rentals. Who needs Netflix? Three days is too long to wait for a movie which may not even be the one you want.

Message to the MPAA, don't go the RIAA route. Don't wait for the market to create itself through piracy. Actually I already enjoy this with Starz! on demand (or whatever it's called). I can download whatever is showing on TV, all month for 14 bucks. Good deal considering it's more movies than I can watch. Plus they all start when I want to and I can control it like a PVR.

More money going to the MPAA since they can cut out the chunk the theatres take; and hence be able to offer the service for less than the price of your typical movie ticket. As more elaborate home theatre systems become a more common place, how long will it be before high quality video on demand to the home will be sought by the general public.

That's interesting, for IPv6 the single and multiple stream records are the same, but for IPv4 the single-stream is considerably slower. I'd very much like to see an explanation of why this is so.

The single stream is the hard one to break, which is why it is lower and still in the hands of Sunet & Sprint... ;-)

The fact that v6 records are similar for both probably means they hit some kind of implementation or infrastructure limit that does not per se limit TCP but rather total bandwidth. But here I'm just guessing.

"However, we have been remiss in not realizing that, like blank media, network bandwidth is also mostly used for piracy.

Well, actually, as long as you do not drop packets (or have other similarly detrimental stuff like weak LAN switches) in the network, all this is a game about basically three things:

1. Bandwidth, which is easy, as long as you have the money.

2. Routing your packets strange paths so that you get enough fiber kilometers between the end nodes. Requires the assistance of your friendly multigigabit ISP.

3. Tuning, tuning, and then some more of tuning on the end nodes. This is where it counts. Most OSes come with a very conservative set of values for its TCP parameters and getting it right requires serious work with clear understanding of TCP. I would fully expect Microsoft to be very active here, to the point of getting Stanford some good assistance from the kernel/networking people in Redmond. The same of course applies to NetBSD, which is what Sunet uses, except in that case we all get to take a peek into the setup. (http://proj.sunet.se/LSR2/)

So, the net is not the problem -- just don't drop packets, get a long string of glass, and get some bigass routers, and you're done. The end nodes are the deal. Microsoft knows this, and pour money into it.

Distance is as impressive as speed

Re:Distance is as impressive as speed

The distance involved is actually more impressive than the speed. 10Gbps isn't really that difficult if you aren't travelling outside of your own server room, and are using a simple device like a traffic generator.

However, the article had some interesting math:

"If you have a million customers and they each have a gigabyte of storage, that's a petabit," he said.

Actually, that would be a petabyte.

Re:Distance is as impressive as speed

[hey!]

Well, not really. If you can move N GB/s 1000 miles, you can move it almost as easily 9800 miles, provided you have the fiber optics to do it.

The raw speed is impressive. Consistently getting a tenth of that rate rate through many hops in a dynamically shifting network for some time would be impressive. Ordering up the stream and getting it back within a guaranteed latency over that distance would be impressive. Increasing the distance is, well a little impressive, but not that impressive.

For example, one limiting factor is that the fastest available interface for PCs is the PCIX64 Bus Isolation Extender, which can only handle 7.5Gbps.

So... Let me get this straight... The problem these guys have is that they are using PC to connect to, and send data on, Internet2?

Just because you're using an operating system that is a close relative in terms of technology used doesn't make the computers the same category.

UNIX was an operating system originally developed for minicomputers. This doesn't mean that my IA32 *BSD machine is a minicomputer -- it _is_ a PC.

Although, that said, I've never used a Next Cube, but I understand they were marketed for single user desktop use, which in my book means they are PCs (or at least, personal computers).

Re:Interesting point...

[hackstraw]

At first I didn't think that you quoted the whole sentence, but you did. It starts with "For example,". It never says that they used a PC. Plus, I don't know of any computer that can survive outside of a server room that money can buy that has peripherals faster than what you can get on a PC. Plus, assuming that the data that was transfered from some kind of storage device (it may very well have been cached into RAM first, or even done in parallel from more than one computer), I don't know of any storage device that can handle anything near 7.5Gbps (7.5*1024/8 = 960 MBs). The fastest storage I know of is fibre channel that can sustain 400 MBs.

This is a pretty impressive feat that is pushing the envelope of all existing computer and networking hardware.

Also, at the end of the article it says:

The technology used in setting this record included S2io's Xframe 10 GbE server adapter, Cisco 7600 Series Routers, Newisys 4300 servers using AMD Opteron processors, Itanium servers and the 64-bit version of Windows Server 2003.

The AMD servers specs can be found here. I don't know if you consider that a "PC" or not. The best offerings in the Itanium department is from HP, and you can look at those guys here. Again, I don't know if you conder those a PC or not, but at least at the lower end of the Itanium family they use the same PCI architecture that PCs use.

Re:Interesting point...

[mbbac]

Although, that said, I've never used a Next Cube, but I understand they were marketed for single user desktop use, which in my book means they are PCs (or at least, personal computers).

Which was my point. I think Tim Berners-Lee was a serious (not computer) scientist and he was using a Next Cube to develop a way of easily retrieving information from his and others' mainframes.

And the OS I use isn't a close relative, it's the latest version of that same OS that was used on the Next.

In my opinion a NeXT Cube was a workstation and not a PC, at least at the time in which it was rolled out. It was kind of like the business version of a macintosh.

Hell, back in the bad old days of SLIP lines and 28.8k modems, circus.com's webpage (a geek house I lived in for a while) was hosted from a turbo slab that sat in bedroom of one of the residents.

I suspect that a 16 disk RAID 0 array of high speed disks could keep up with this. However, I think you'd need a pretty specialised computer system to keep up with such an array. I'm not sure what kind of architecture you'd need, but I am convinced it would involve multiple I/O buses and some kind of crossbar arrangement for shared access between DMA controllers. Memory would have to be interleaved carefully also.

Chances are they were transferring localhost:/dev/zero to remote:/dev/null.

Re:Achieving equivalent Disk I/O

[menkhaura]

Does Windows have /dev/zero or /dev/null?

Zeroes can be quite heavily compressed, this would yield a pretty good transfer rate. TFA doesn't mention whether the data was checked at both ends with, say, MD5sum (it doesn't mean it was not checked).

Windows has named pipes. A few of them are very well known. For example, COM1, COM2, PRN, et cetera. A less well-known named pipe is NUL, which is your /dev/null equivalent. There is no /dev/zero equivalent; the OS won't generate nulls for you, you have to generate them yourself (oh the horror.) NUL dates back to DOS, which wanted to be like Unix. Well, a little bit like it. While you clearly can run something like legacy Unix on a 4.77MHz PC, the OS would consume too much of the machine so we ended up with something only a tiny bit like Unix instead.

Re:Achieving equivalent Disk I/O

[julesh]

NUL dates back to DOS, which wanted to be like Unix. Well, a little bit like it.

[Anonymous Coward]

The article said 859 Gb in 17 minutes, but 6.63Gbps according to my calculations is 6762 Gb in 17 minutes. That is unless they are saying that the maximum speed they reached was 6.63 Gbps and the total transferred was 859 Gb.

[TwoStepsBehind]

So let's use the commonly presumed capacity of the brain: 10 ^ 15 bits.... Now children, "How long would it take to download a brain that is full?" Class responds: At 6.63Gbps, it would take 150,829.6 seconds, or about 1.74 days, or about 41.89 hours! Good job class. So it would take 41.89 hours to download the brain. Class, "Now how long would it take to download the brain of our current president?" Class responds: We'll let you know when we've located his brain! :)

How much?

[jimicus]

'transferred 859 gigabytes of data in less than 17 minutes.'

That's a helluva lot of pr0n. I think there is a need for a definition of speed in terms of "number of horny people who can be satisfied per second".

Assuming a couple of hundred KB for a high-res JPEG, or about 30MB for a short film, 6.3Gbps would be equivalent to about 20 films or 3150 images per second.

With it's a 75/25 split between movies and still images, that's 15 films and 750 images.

Or 765 orgasms per second.

Re:How much?

[afidel]

Ah, but you have a flaw in your logic, you have assumed that one picture equals one orgasm. From my "research" that is almost never the case. In fact to get real numbers you would have to do a study to determine the average number of pictures and the average number of short movies it takes for the average consumer to view before achieving orgasm. Then you could calculate the orgasms per byte (and the relative densities thereof) and thus derive your orgasms per second given the network speed. The research is already being carried out all over the internet, we just need some way to record the data and tabulate the results, perhaps there is a use for spyware afterall =)

You are not going this right.
6.63Gbps/8=0.82875GBpsx 4 = 3.315 GB.

So basically you would be transfering a short movie (assuming a long movie at 4.4GB).

Re:bits or bytes?

[Anonymous Coward]

6.63 GBits / Sec = 0.82875GBytes / Sec

0.82875 GBytes / Sec = 3.315GBytes / 4 Sec

a DVD can store ~4.7GB, so for a full DVD you're looking more about 5.7 seconds, but typically a DVD movie isnt full.

So yes, you're not doing it right, but they're still a bit out depending on whether or not you're a pedantic sod.

6,63Gbps = (6,63 x 1024 x 1024 x 1024) / 8 = 889863536.64 bytes per second or 848.64 Mega bytes per second
848.64MB x 4 sec = 3394.56 Mega bytes

It seems to me this looks ok.

Re:bits or bytes?

I don't think you're doing it right...

Supertanker "error correction" features?

You bring up a good point. The bandwidth of a station wagon full of DVDs or a supertanker full of whatever is pretty big and while it's slow physically, it might take less time to ship.

However, I've been thinking about this. How long does it take to burn the DVDs? How long does it take to load up? And what about accidents? Cars are notorious for their statistical lack of safety compared to other transportation methods. One small rear end collision is all you need in a station wagon. And the supertanker better be double hulled or we could end up with a new idea for "data flow" as it flows down the coast.

What's a minicomputer?

[tepples]

UNIX was an operating system originally developed for minicomputers. This doesn't mean that my IA32 *BSD machine is a minicomputer -- it _is_ a PC.

Then define minicomputer. Some sources define a minicomputer as any computer with virtual memory and a personal minicomputer as any mini used as a PC. To them, just because you use your personal minicomputer as a workstation doesn't make it any less of a mini.

I've never used a Next Cube, but I understand they were marketed for single user desktop use, which in my book means they are PCs (or at least, personal computers)

If you define "minicomputer" to require multiple users, then what's Windows XP's "fast user switching"? It's multi-user desktop use. And what's "Internet connection sharing" of Windows? It's using your PC as a server.

Scalability?

[Thedalek]

These Internet speed record experiments are interesting, but the issue of scale is rarely addressed. Okay, so a team of researchers were able to go faster than the speed of bad news, but what happens when the server load is a bit higher than just one transfer?

Or does Internet2 use some exotic de-centralized transfer method that renders the paradigm of servers laughably obsolete?

Re:CPU

[julesh]

Not sure about MD5 but SHA1 (which is more complex, even) can be calculated with about 15 CPU cycles per byte on Intel hardware, if you write the implementation using SSE instructions. If your machine were hashing at the most efficient rate possible, it would have taken less than 2 minutes. You have to add to this, of course, disk to memory transfers, cache and pipeline stalls, overhead of switching to any other tasks that needed to run, etc. Chances are the application wasn't smart enough to buffer the data ahead of time to try to keep a full pipeline of data to process, which is the main reason for the slowness here.

"Jenna Jameson's new DVD just game out and we wanted to see how fast we could send a copy...er, backup...to our pals at MIT. We wanted to send the whole thing in two seconds, but we would have had to leave out the special features. No way we could do that."

[evangellydonut]

According to the article, they'll need to xfer 15PB of data in a year...let's see...

6.63Gbps = 0.82875GB/s * 3600s/h * 24 h/d * 365 d/yr / 1024 GB/TB / 1024 TB/PB = 24.9PB/yr

In other words, they'll have to run at ~60% capacity sustained, which is pretty insane...

It wouldn't supprise me if it gets tried

[Sycraft-fu]

At some point. The thing of I2 is it's a member's only club. No external traffic is routed. Well, this means with a little network research, one could write a P2P program that would share ONLY from and to I2 nodes. This would ensure fast transfers... but also make it very hard for the RIAA to monitor. Since the RIAA isn't the kind of group that can get hooked to I2, the nodes wouldn't talk to them. They'd have to get a university to help them.

Interestingly enough

[Sycraft-fu]

Moving harddrives IS the fastest way to send large amount of data for most people. FedEx next day air and even often ground, is just faster than your ent connection can do for large amount of data unless your speed is truly insane.

I mean let's say you need to send 2TB of data to someone. Not as uncommon as you'd think for video work, image research, rendering, etc. So you have a blazing fast line, 100mbit. Unlike the DSL over in Korea that people like to brag about, it's connected to an ISP that has the upstream so you can get that to everywhere. Other side has the same thing as you.

Well, supposing you went full bore using the whole connection and getting 100% efficiece for 24 hours, you'd have transfered only about half your data.

However, if you were to stick the HDs in a box and next-day air them to the site, they'd all get there. Also eliminates the need to maintain a really expensive connection.

They needed data. They started with DVDs they owned, but a few dozen only added up to about 1/8 of what they wanted. Renting was too expensive and they were worn out from ripping the first 12. The solution was obvious ...

The connected the Winblows 2003 server and used it to collect data. Within minutes, it was rooted and it's reputation for good network connectivity spread quickly. In a day or two, the multiple terabyte array was filled with music, movies, porn and warez. The data was then transfered to reasonable hardware and the test was performed.

Perfectly Cromulent

There is nothing wrong with using the word speed, especially when vonerting everything to time.

Agreed, in this context it is a perfectly cromulent word.

Why bother making up a joke, when a quote will do fine. Emphasis is mine:

"Is it possible that building a Unix operating system really only takes a few months --and, oh by the way, you don't even need the source code to do it?" Yes, it is possible, because there are published interface standards. I might have done it myself if it had occurred to me to try -- in fact, I have sometimes wondered why it didn't occur to me.
