New Internet Tech 153,000 Times Faster Than Modem

New Internet Tech 153,000 Times Faster Than Modem

Scientists have developed a new data transfer protocol for the Internet fast enough to download a full-length DVD movie in less than five seconds, the California Institute of Technology said today.
The protocol is called FAST, standing for Fast Active queue management Scalable Transmission Control Protocol (TCP).

The researchers achieved a speed of 8,609 megabits per second (Mbps) by using 10 simultaneous flows of data over routed paths, the largest aggregate throughput ever accomplished in such a configuration, Caltech said in a news release. "That is 153,000 times that of today's modem and close to 6,000 times that of the common standard for ADSL (Asymmetric Digital Subscriber Line) connections."


A new data transfer protocol for the Internet may cause long download times to become a thing of the past. The scientific development dramatically increases the speed of data flow, fast enough to download a full-length DVD in less than five seconds.


"The FAST protocol sustained this speed using standard packet size, stably over an extended period on shared networks in the presence of background traffic, making it adaptable for deployment on the world's high-speed production networks," Caltech said.

Harvey Newman, a professor of physics at Caltech, said the fast protocol "represents a milestone for science, for grid systems, and for the Internet."

"The ability to extract, transport, analyze and share many Terabyte-scale data collections is at the heart of the process of search and discovery for new scientific knowledge," Newman said.

Les Cottrell of the Stanford Linear Accelerator Center (SLAC), which worked with Caltech on the experiment, said that progress in speeding up data transfers over long distances was critical to progress in various scientific endeavors. "These include sciences such as high-energy physics and nuclear physics, astronomy, global weather predictions, biology, seismology, and fusion; and industries such as aerospace, medicine, and media distribution."

"Today, these activities often are forced to share their data using literally truck or plane loads of data," Cottrell said. "Utilizing the network can dramatically reduce the delays and automate today's labor-intensive procedures."

The data was transferred over shared research networks in the presence of background traffic, suggesting that FAST can be backward compatible with the current protocol, Caltech said. The FAST team has started to work with various groups around the world to explore testing and deploying FAST TCP in communities that need multi-Gbps networking urgently.

With Internet speeds doubling roughly annually, the performances demonstrated by the new protocol could become commonly available in the next few years, Caltech said. "So the demonstration is important to set expectations, for planning, and to indicate how to utilize such speeds,"

The testbed used in the Caltech/SLAC experiment was the culmination of a multi-year effort, led by Caltech physicist Harvey Newman's group on behalf of the international high energy and nuclear physics (HENP) community, together with CERN, SLAC, Caltech Center for Advanced Computing Research (CACR), and other organizations.

The experiment was performed last November during the Supercomputing Conference in Baltimore by a team from Caltech and the Stanford Linear Accelerator Center (SLAC), working in partnership with the European Organization for Nuclear Research (CERN), and the organizations DataTAG, StarLight, TeraGrid, Cisco, and Level(3).

The FAST protocol was developed in Caltech's Networking Lab, led by Steven Low, associate professor of computer science and electrical engineering. It is based on theoretical work done in collaboration with John Doyle, a professor of control and dynamical systems, electrical engineering, and bioengineering at Caltech, and Fernando Paganini, associate professor of electrical engineering at UCLA. It builds on work from a growing community of theoreticians interested in building a theoretical foundation of the Internet, an effort in which Caltech has been playing a leading role.

A system will need a TON of memory to realise these speeds or a rather avante garde RAID storage subsytem to collect data that fast.

Cheers!
 
Don't expect this to be mainstream for end users. This is only for businesses that can afford it in the near future.

That's not saying WE'LL all get such speeds. But if such speeds were available, our local ISPs might be able to provide faster bandwidth as well.
 
Give me a break 😛 Tell me when you were chugging along using your 300 baud modem like I was that you even imagined having something the speed of your cable modem in your home 😛 I'm sure even back then phrases like "ah well that will never reach the end-user!" were used.

What's a 'loooooong time' for you? I've been using cable for 6 years now, i'm due for an upgrade i think.

I have had broadband for about 1.5 years now, you've had CABLE for 6 years? There was broadband 6 years ago? 😉

Yep yep. I live by an area that was testing cable broadband... and they accidentally accepted me into the program even though i wasn't exactly in my area. Took them 2 weeks to install all the require requipment outside (they found out AFTER giving me the modem that it wasn't available in my area), but eventually they did. I was the only one in the area with cable for over a year before they started subscribing everybody else. Those were the days... i still remember being able to look in my network neighborhood and being able to see everybody elses computer.
 
Well, let's see... DSL was developed in the 80's and nobody got it until about 1996, I think. Cable came around the same time, with the networks for it installed in the late 80's. Furhtermore, both of those markets have already reluctantly (esp. the phone companies) invested hoards of cash into what they have now. Wonder how long we'll have to wait for this little wonder...
 
Because there wasn't a demand for it until the Internet became graphical and commercialized. Implementation of technology happens extremely fast if there's a market for it.

Tell that to all the people still waiting for cable or dsl to become available to them

<<Hand up>> Dsl or ADSL would be good here to......i have 56k...or so im told i normally connect at 28.8....not funny ill be dead by the time we get that...
 
Am I the only one left wondering how the hell it works? A bit is a bit is a bit, no matter what protocol, and if a line can only transfer so many bits, that's it. What does this replace? Ethernet? IP? TCP? I don't get it. From how it's explained, the only way I see it being possible is by compressing the data, but that's variable, and slow.
 
Nerd: "I've invented a way to download porn from the Internet a million times faster."
Marge: "Why would anyone need so much porn?"
Homer: "A million times....gaaaghhhhh"

Or something like that.🙂
That's what came to mind when I saw this. 😀

This technology looks nifty; wonder if it'll ever actually make it to the market, and be profitable?

im in the exact same boat only i only connect at 26.4
