Five Ideas That Will Reinvent Modern Computing

Excerpts from the article:
The classic point-to-point networking model is fundamentally flawed. Today, if you want a piece of data from the network, you almost always need a direct connection to the data's original source—the server. That's true even if the data has already been downloaded to a device that's much closer. So often, tapping into a distant server wastes time. And if the server is unavailable, you're out of luck entirely.
With a project called Content-Centric Networking, or CCN, Jacobson and his team of PARC networking gurus are turning this model on its head. They're building a networking system that revolves around the data itself, a system in which a router can actually identify that Bode Miller video and act accordingly. Under the CCN model, you don't tell the network that you're interested in connecting to a server. You tell it that you want a particular piece of data. You broadcast a request to all the machines on the network, and if one of them has what you're looking for, it responds. "You can authenticate and validate information using the information itself—independent of whom you got it from," says Jacobson...
