Content-Centric Networking & the Next Internet

waderoush writes "PARC research fellow Van Jacobson argues that the Internet was never designed to carry exabytes of video, voice, and image data to consumers' homes and mobile devices, and that it will never be possible to increase bandwidth fast enough to keep up with demand. In fact, he thinks that the Internet has outgrown its original underpinnings as a network built on physical addresses, and that it's time to put aside TCP/IP and start over with a completely novel approach to naming, storing, and moving data. The fundamental idea behind Jacobson's alternative proposal — Content Centric Networking — is that to retrieve a piece of data, you should only have to care about what you want, not where it's stored. If implemented, the idea might undermine many current business models in the software and digital content industries — while at the same time creating new ones. In other words, it's exactly the kind of revolutionary idea that has remade Silicon Valley at least four times since the 1960s."

Magnet links?

Did he just reinvent magnet links?

[Anonymous Coward]

Is your actual premise here that Van Jacobson, a major contributor to TCP/IP and inventor of the modern flow control it is based on, somehow doesn't have the foggiest idea how the infrastructure HE HELPED FUCKING INVENT works?

My concern is, whenever I hear about "re-inventing the internet"...is that if we do it, this time around, all the government types will want to have protocols in there to assure no anonymity, tight control...and likely make it difficult for the avg person to hook a computer to the internet of the future, and become a true peer.

The genie is out of the bottle, even still today on current internet setup....I'd not count on the govt types allowing the next one, to have a genie....by force of law.

Isn't the internet already meeting demand?

Why does he say "it will never be possible to increase bandwidth fast enough to keep up with demand"?

When I want to watch streaming video, I fire up Netflix and watch streaming video. When I want to download a large media file, I find it on bittorrent and download it. The only time I've noticed any internet slowdowns, it's been in my ISP's network, and it's just a transient problem that eventually goes away.

Sure, Netflix has to do some extra work to create a content delivery network to deliver the content near to where I am, but it sounds like the internet is largely keeping up with demand.

Aside from the IPv4->IPv6 transition (we've been a year away from running out of IP addresses for years), is there some impending bandwidth crunch that will kill the internet?

it will never be possible to increase bandwidth fast enough to keep up with demand.

I've been hearing that since I got on the net in '91. Tell me a new lie.

Its an end time message. "Repent, for the end is near". Yet, stubbornly, the sun always rises tomorrow.

But I *DO* care where my content comes from!

[jmac880n]

There is a huge chunk of the Internet that cares very much where the content came from:

• Who exactly is asking me to transfer money out of my account?
• Did this patch that I downloaded come from a reputable server? Or will it subvert my system?
• Is this news story from a reputable source?

And the list goes on....

None of these depend on the location of the data, only the identity of the author. If you can verify the integrity of the data, where you get it is irrelevant.
