Arguments for an Information-Centric Internetworking Architecture
The current Internet architecture focuses on communicating entities, largely leaving aside the information to be exchanged among them. However, trends in communication scenarios show that WHAT is being exchanged becoming more important than WHO are exchanging information. Van Jacobson describes this as moving from interconnecting machines to interconnecting information. Any change of this part of the Internet needs argumentation as to why it should be undertaken in the first place. In this paper, the authors identify four key challenges, namely information-centrism of applications, supporting and exposing tussles, increasing accountability, and addressing attention scarcity, which the authors believe an information-centric internetworking architecture could address better and would make changing such crucial part worthwhile.
