> Named data networking (also content-centric networking, content-based networking, data-oriented networking or information-centric networking) is an alternative approach to the architecture of computer networks. Its founding principle is that a communication network should allow a user to focus on the data he or she needs, rather than having to reference a specific, physical location where that data is to be retrieved from. This stems from the fact that the vast majority of current Internet usage (a "high 90% level of traffic") consists of data being disseminated from a source to a number of users.
(Another idea with a Ted Nelson pedigree, btw.) Van Jacobson's working on another, NSF-funded project in this area http://named-data.net/ at present.
