Report of the NSF Workshop on Software Defined Infrastructures and Software Defined Exchanges

Robert Ricci and Nick Feamster




We are at the dawn of a new era: Software Defined Infrastructure (SDI). Today’s relatively static cyber-infrastructures, implemented via hardware with predetermined control systems, are now beginning to morph into fluid, planetary-scale software systems – highly interconnected, deeply programmable, and virtualized within end-to-end slices across many administrative domains. SDI’s forerunners include multi-tenant clouds, 1 software defined networking, network functions virtualization, and software defined radios. Individually, each presents major research challenges. But viewed within the broader SDI context, they are simply starting points of a very deep revolution that will reshape our global computing infrastructure.
