IP was Middle School, Named Data Networking is College

Bob Brown | Oct. 9, 2015
With Cisco, Intel and a bunch of academics behind content-centric NDN Internet architecture, momentum picks up.

Jacobson took it from there (and you can see/listen to his presentation in the YouTube video below, a bit after the 1-hour mark): 

“When you’re telling stories you need a vocabulary, you need idioms, you need ways to express those stories, and we’re telling stories as computer scientists, particularly networking researchers, with our protocols, with APIs, with packet formats. And the thing that kicked off all the [Future Internet Architecture] efforts was this frustration in the community that telling our stories with IP is getting really hard. It’s like our tools are working against us, not for us. We spend like 80% of our effort trying to bash the tools into shape and only spend 20% on the problems. In vocabulary terms, IP is like a good middle school education. There’s a lot of things you can say and communicate in society but it’s not so great for writing a poetry volume or a thesis. The Web kind of brought us up to high school and the expressivity in things like XML and Ajax. You can work at a higher level, accomplish a lot more, but you’re still pretty limited by this conversational client-server model. The real goal of NDN was to get us into college. To have a set of idioms, vocabulary that would let us naturally express the high-level things that Jeff presented, that we want to see.” 

Jacobson went on to highlight new thinking in data transport, Internet security and routing. Routing, he said, has been long overdue for an upgrade. "For the past 40 years, unfortunately, we've been doing routing based on Paul Baran's original model of building paths through graphs and then binding identities to the ends of those paths. There's a lot of downsides in doing routing that way." He pointed to new geographic routing models prototyped in NDN that can be more efficient.

If you’re playing catch-up on NDN, don’t sweat it, as it really is still early despite the progress that's been made over the past few years. The good news is that a growing body of content is available online to help you bone up. NDNComm is making its presentations available in streaming and PDF formats, and a slew of tutorial videos are available from the ACM event.
