NFV Relationship with SDN
Decoupled
Server Virtualization Network Virtualization
§ Decouple logical & physical topology
§ Network is an abstraction.
§ Programmatic Provisioning.
§ Place any workload anywhere.
§ Move any workload anywhere.
§ Decouple from Hardware.
§ Provide L4-7 network services
§ Operationally efficient.
NFV with SDN in an open environment, provides very powerful benefits to SPs

Integrated Tools
• Extremely Easy Fabric Automation • FCAPS with Day 1 & 2 operations • Matured Technology • Easy to Consume • Physical, Virtual, Containers
• Decoupled SDN controller from physical fabric.
• Needs externals tools for FCAPS • Relatively complex to design, implement and operate.
Segment Routing Based DC Fabric
• Early adoption phase for transport layer • Currently lacks automation &
Operational tools • Integration with Virtualization layer • Vendor interoperability to be determined

Containers • Hypervisor solve interdependencies
between apps but… • Heavyweight 100’s of MB and slow to start
20 seconds or so • Enabler for OpAmial Resource & Agility

Summary And Discussion Points Raising key questions:
• How does SDN/NFV add to economic and strategic value to your business?
• How much of automation of Physical & Virtual services has been achieved?
• How do you plan to manage the complex cost of transition effectively?
• What's the value you plan to derive out of Open source tools? People Process Tools
SDN/NFV is a strategic technology transformation • Its not about virtualizing a VNF on a bunch of servers • Its about hosting VNFs on a Open, Programmable, Intelligent
Network Infrastructure with flexibility to Manage and Automate Services
Leading to high Operational disruption …
