Explanation:
The current top hit when you search for SONA, http://www.cisco.com/en/US/netsol/ns629/index.html, confuses the response to this question.
It looks like they are now calling the physical infrastructure, what used to be called the network infrastructure layer in older publications (e.g. http://newsroom.cisco.com/dlls/2006/eKits/sona_fact_sheet.pdf)
From the above referenced fact sheet:
“Three Layers of Cisco SONA
· The Networked Infrastructure layer, where all of the IT resources are interconnected across a
converged network foundation.
· The Interactive Services layer, which enables efficient allocation of resources to applications
and business processes delivered through the networked infrastructure.
· The Applications layer, which contains the business applications and collaborative applications
that leverage efficiencies from the interactive services.”
