Towards A Content-Oriented Internetwork

Speaker: Rajesh Krishnan

Abstract

The Internet counts among the greatest human accomplishments of the 20th century. Over a billion people access content over the Internet today; ironically, the Internet per se is content-agnostic, and infrastructure for content storage and retrieval has been overlaid separately. The core problem of the Internet has changed since its inception (from end-to-end data conversations to distributed content access), and so have resource constraints (for example, storage is not quite as expensive). Is it time to envision and create a new content-oriented internetwork?

In this talk, I will introduce the area of Delay/Disruption-Tolerant Networking (DTN), which I interpret as a generalization of traditional data networking along several important dimensions. I will posit that DTN is a "disruptive" technology and that emerging DTN innovations and standards can pave the way for a content-oriented internetwork of the future. I will touch upon research and key challenges in this area.
