Summary

Starting in August of 2006 our collaborative team of researchers from North Carolina State University and the Renaissance Computing Institute, UNC-CH, have been working on a Future InterNet Design (NSF FIND) project to envision and describe an architecture that we call the Services Integration, controL, and Optimization (SILO). In this chapter, we describe the output of that project. We start by listing some insights about architectural research, some that we started with and some that we gained along the way, and also state the goals we formulated for our architecture. We then describe that actual architecture itself, connecting it with relevant prior and current research work. We show how the promise of enabling change is validated by showing our recent work on supporting virtualization as well as cross-layer research in optics using SILO. We end with an early case study on the usefulness of SILO in lowering the barrier to contribution and innovation in network protocols.

Toward a new Internet architecture

Back in 1972 Robert Metcalfe was famously able to capture the essence of networking with a phrase “Networking is inter-process communication,” however, describing the architecture that enables this communication to take place is by no means easy. The architecture of something as complex as the modern Internet encompasses a large number of principles, concepts and assumptions, which necessarily bear periodic revisiting and reevaluation in order to assess how well they have withstood the test of time.
