David Clark: Rebuild the Internet
boarder8925 writes "David Clark, who led the development of the internet in the 1970s, is working with the National Science Foundation on a plan for a whole new infrastructure to replace today's global network. The NSF aims to put out a request for proposals in the fall for plans and designs that could lead to what Clark called a 'clean slate' internet architecture. Those designs, Clark said, could be tested on the National LambdaRail, the nationwide optical network that researchers are using to experiment with new networking technologies and applications."
"A whole new infraestructure" you say?.
We cant even start using the new ipv6 protocol. I dont think we are there yet. Try in 10 or so years.

...is this project going to actually provide revolutionary designs to ease or eliminate the problems we face today, or is this just a matter of reinventing the wheel?
I realize that it's quite tempting for computer developers to want to clean up a system after it's done, but such work only ever works if you have a clear understanding of the problems faced under the current codebase as well as an absolute need to fix the issues with the current system. Simply saying, "it'll be better/cooler/faster" just doesn't cut it. Those things can be obtained from evolutionary development. Revolutionary means that you are uprooting all the existing users. The payoff MUST be tremendous or they ignore it!

Clark said he would like to see two things addressed in any replacement for the current internet. The first is a coherent security architecture. The second is a healthy economic infrastructure for network service providers, who will need a bigger piece of the pie in the new internet than the one they are getting now if they are going to help pay for building it.
I read this as users having no anonymity and paying through the nose for it.
Can I just keep the old internet?
PHP and MySQL which can do anything!
"Fuck it! I'll rewrite it from scratch."
That approach is always more fun
"A super-high-speed internet could even allow people a world apart to collaborate inside elaborate 3-D virtual arenas, a process called tele-immersion."
I believe the technical term for this is MMORPG. It appears to work pretty well with our current internet.
All joking aside, I don't think anything will change any time in the near future. IPv6 is probably the most radical change the internet will see for possibly decades to come, and that can't even catch on. People are simply not going to pay to have the internet re-architected when it is working well enough as it is; why reinvent the wheel while its still rolling. Things along these lines have been proposed before, and I'm sure will be proposed again, and I'm sure that one day, the internet will eventually be rewired. However, this is still far ahead of its time.
Cars still ride on wheels, power still goes out with storms, and cell phones still lose service underground. What makes anyone think the internet is going to be any different.
I'll agree with him that Internet2 hasn't lived-up to what it should have been, and trying something completely different would be a very good idea.
However, I don't agree that the current internet is in-need of replacement. Creating TCP/IP packets requires significant processing power, and a simpler protocol would mean more devices being online, but by the time anything new becomes accepted, a $1 chip will be able to do it all.
If you want to improve the internet, put explicit congestion notification back into all TCP stacks, as it was before the BSD stack left it out... Goodbye massive packet loss due to minor congestion. Require all vendors to support jumbo frames... And many more small changes (to the existing internet).
Slashdot gets worse every day... Pipedot: News for nerds, without the corporate slant
I've been to IPv6 summits. I've also served as the senior technology officer for several telecom companies (one of which was a very first CIX-W router connected ISP and frustration to Paul Vixie in our rather unique connection to the early Santa Clara peer point).
Through my experience, I've advocated IPv6, yet I've found significant resistance from nearly all sectors of business (except from South Korean and South American investors - go figure). Some of the problems IPv6 plans (and this "new infrastructure" pipe dream) face include:
Don't think I'm not wild about IPv6. I geek out and run it over AX.25 amateur networks for fun (what better way to learn a protocol). Yet the days of getting capital markets worked up in a frenzy, ready to throw hundreds of millions at network replacement are gone. Unless this latest dream is based on new tax revenues from all of us (which only creates messes like the original unaccountable NSFNET regionals), it won't go anywhere.
*scoove*
Don't fix what ain't broken.
Sure, there's almost always better ways to do things that are only illuminated by hindsight, but that doesn't mean that the old way should just be tossed out and replaced.
Besides, the Internet is one of those amazing flukes of history. It's a very open, public, and free world unlike anything before it. Does anyone really think that something designed now in the age of terrorism, by committee, using government money (NSF) would be carefully designed to protect those initial design elements that make the Internet what it is today?
Hexy - a strategy game for iPhone/iPod Touch
If one is able to find any privacy or anonymity in this new Internet, it will be because of some undiscovered security hole, which will be quickly repaired, rather than any kind of conscious design decision. Probably one reason they are accepting proposals before rolling it out is to avoid the sort of accidental security holes that enable pr0n, peer-to-peer filesharing and left-wing political activism.
Microsoft, a leading contributor both to this nation's technology base and to the campaign coffers of its leaders, will embrace this new technology and extend it in such a way that the development and dissemination of Open Source software will be, if not mathematically and physically impossible, at least as difficult as factoring a 2048-bit public key.
Imagine, if you will, Trusted Computing implemented at the router level, in such a way that any packets that go farther than one hop are certified not only to support protocols whose patent licenses are fully paid-up and on file with the legal department in Redmond, but whose content is compliant with the Windows standard. The faintest whisp of a Public License, GNU or otherwise, will result in the dropping not only of the individual packet, not only in the cancellation of the entire file transmission, but, within microseconds, the physical location of the offending server. The identities of its rogue administrators will be fetched instantly from the database maintained by the Homeland Security Department. (You will have to submit fingerprints and DNA samples to obtain a Windows server license, as after all, Internet servers can be used to disseminate explosives recipes or the formulas for nerve gases.) The supercomputers that constantly monitor the cameras mounted on every lampost in the United States of (God Bless It!) America will be ordered to recognize the criminals' faces, and when they are spotted trying to flee to the Amazon jungle, orbiting lasers will vaporize their bodies, leaving nary but a whisp of smoke.
When a close family friend tries to comfort one of the grieving mothers for the loss of her son, she will desperately proclaim "No, I have no children! You must have mistaken me for someone else. Please leave me alone!" before she scurries rapidly away.
National firewalls such as those employed by The People's Republic of China are expensive and difficult to maintain. They are notoriously leaky, and easy to circumvent by anyone determined enough to find out how. But worse, they impede the economic potential of emerging economies such as China, which necessarily bottleneck technical data and eCommerce in order to have a single chokepoint for the Four Horsemen of the Infocalypse (Taiwan, Tibet, Hong Kong and Pornography).
Imagine, if you will, the potential of our New Internet: not only by technical design, but by international treaty (enforced by the threat of military intervention on the part of the UN Security Council), each nation will have a national firewall which is as transparent to the air to fully-licensed Windows Media Video files of Barney the Dinosaur and paid-up Wal-Mart orders, yet absolutely impenetrable to content not sanctioned by Homeland Security, the Republican Party, the 700 Club and the Boy Scouts.
I, for one, am weary of our present Internet, cesspool that it is of moral depravity and copyright infringement. I long for the days of yore, when men were men, women wore hoopskirts, and racial minorities were separate but equal. And so, I raise my right hand and shout with an enthusiastic "Heil!":

When you're done with the old Internet, can we have it?
Hugs,
The Developing World.
Crumb's Corollary: Never bring a knife to a bun fight.
Thanks for making "secure by default" less important.
Thanks for retarding IPv6 development.
Thanks for necessitating the invention of UPnP.
Thanks for screwing up peer to peer connections for legitimate things like videoconferencing and file transfers.
Thanks for continuing to allow ISPs to treat IP addresses like some sort of rare element.
Thanks for mangling things like FTP.
This guy must be getting support from a telco.
Telecommunications providers hate the Internet. Not only is the Internet too cheap, it's not set up for detailed billing. The US Internet backbone cost about $1bn to build, and costs about $100 million per year to run. For something that handles over 100 million users, that's nothing. All the intelligence is in the end nodes, so telcos don't get to add "value added services" for which they can overcharge.
What telcos want is an environment they control, like cell phones. With charges for everything from ring tones to SMS messages. That's what Clark is talking about here.
The telcos tried this idea back in the 1980s, and it was called TP4, or "ISO 8073 COTP Connection-Oriented Transport Protocol - X.224" X.224 is very much like TCP, but without the adaptive retransmit machinery to work well over unreliable links. You're supposed to run X.224 over a reasonably reliable virtual circuit provided by a telco. For which you pay by the packet, like X.25 or ISDN. Bad idea. Windows NT4 actually had support for X.224, and some older Cisco routers understand it, but it's dead.
This is not a place we, as users, want to go.
Guys, guys GUYS!
I see many posts here about how we need to "mandate" this and "require" that and blah blah blah...
But the Internet, by design, is lasse faire! There is no "mandating" ANYTHING! Anybody can hook up to their neighbor, who hooks up to some guy across town, who is hooked up to a couple other folks...
The Internet is DECENTRALIZED and OPEN. The closest it gets to mandating anything is the much-disputed RBLs. I, for example, block all email from most Asian countries - nothing personal, but it sure drops the SPAM load with virtually no complaints. But, I can't mandate what the Chinese or Koreans do with their network - I can only mandate what they do with respect to MY networks.
The Internet is merely a commonly agreed upon set of standards for communications across disparate networks, and it's performing the task of connecting networks the world over with grace and flair.
Don't tell me that just because Windows systems get infected in 12 minutes, that the Internet is broken. Sorry. The Internet is working fantastically. It's Windows that's broken. It's not up to the task of functioning on a globally accessable network.
So far, every significant "problem" I've heard with the Internet hasn't been with the Internet, but with the systems at its fringes. SPAM. zombies. Worms. Viruses. Exploits. All are simply side effects of a "zero friction network" as espoused by the all-knowing Bill Gates in his 90's book, "The Road Ahead", combined with systems not able to cope with the ramifications.
Bill Gates, Larry Ellison, Scott McNealy, Linus Torvalds, and all the others are learning now what that truly means, and over the next decade or so, we'll see major advances in developing the kind of security needed to handle this frictionless network.
In short: the Internet is doing just fine, people! It's the systems hooked up to it that have problems!
I have no problem with your religion until you decide it's reason to deprive others of the truth.
