In-Depth Look at the ASR Router

Back on March 5 blogger extraordinaire Alessandro Perilli of revealed that Cisco had chosen KVM as the virtualization platform for IOS-XE, the new Linux-based version of IOS that runs on the recently introduced ASR series of routers.

If you were like me, you may have been wondering exactly how Cisco was putting KVM to use. No need to wonder any longer! Colleague and fellow blogger Colin McNamara has written up a detailed and in-depth discussion of the ASR1000 and how it uses KVM to provide virtualized instances of IOS-XE. Colin also discusses the role of the QuantumFlow processor and, believe it or not, the role of Popeye and Spinach. (Go read the article. It will make sense when you’re done.) Nice work, Colin!
