Virtualization Revisited Diversified Internet Project (Wash U) Cabo Project (GaTech, Princeton, UMass) Ambassadors from Reality (AT&T, Google)

Network Virtualization Subdivide/share physical components –Nodes –Links –Forwarding tables Why this is a good idea –Pluralism –Isolation –Customization –Amortization Two related questions –How to support it (metarouter, VINI) –What to do with it once we have it (splicing, UFO, HORN) The main requirement of a future network architecture is the ability to run multiple virtual networks in parallel.

What is Virtualization? Parameters include –Resource Isolation –Customization Different application constraints, different hardware support –Are there a common set of features … to support virtualization? … to support scalable, highly available routing? … to support scalable, incrementally deployable, secure routing? Resource Isolation Customization Splicing UFO HORN L3 VPNs Overlays L2 circuits

Agenda Update on virtualization-related projects –Support for virtualization and substrate –Applications of network virtualization Outreach and collaboration activities Industry Reactions and Experience –Vijay Gill (Google) …? –Kobus van der Merwe (AT&T)

Goals of Session Update on current status Experience with cross-project collaboration Feedback and experiences from industry –Experiences –Reactions Brainstorm
