In reply to R Scott.

Cisco has been the first to build sophisticated virtual networking with the Nexus 1000V - 5 years ago and innovated on VXLAN and vPath as well as consistent cross-hypervisor virtual networking. I will refer you to my previous post http://blogs.cisco.com/?p=123979 for some background. Market share numbers are little difficult to track. We have more than 8500 paying customers and that shows our wide adoption in the market.
