The document discusses leveraging NFV infrastructure to drive new revenue streams. It defines NFV as replacing closed network appliances with virtual network functions that can run on any open hardware. While VNFs are typically run in the cloud, some functions need to be located in the access network for reasons like routing, security, and performance. The document proposes an NFVIaaS model where a facilities-based operator provides a server with virtual infrastructure in the access network, allowing service providers to host their VNFs locally without on-site equipment. This creates new revenue opportunities for operators and lower costs for service providers.

Why Put NFV in the Access Network?
VNFs can’t always be put in the cloud.
• Some functions need to be in the access network:
• Routing for resiliency (e.g., dual-homing)
• Security
• WAN optimization
• Wi-Fi control
• Performance assurance and diagnostics

Tim Naramore
Masergy wanted to go from three or four
boxes to one – and they did.
The next step is no boxes.
How can Tim achieve his goal of deploying
NFV at the customer site with no Masergy
box?
