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?
