Network Function Virtualisation
• Its not SDN !
• SDN opens up the
control & data plane
• SDN primarily protocol
oriented
• SDN primarily centers
on Flows

Network Function Virtualisation
• Commodity Hardware
• White Box Switch
Vendors
• Innovations in x86
processor architectures

What is NFV?
Potential to disrupt the way the Internet is built and managed
• New Entrants (e.g. white boxes)
• New Services (e.g. NFV Marketplace)
• New Business Models (NFVaaS)

Network Complexity
ReducingRevenues
Costs of equipment, maintenance, management are not reducing with complexity !

Network Complexity
ReducingRevenues
NFV offers new and innovative means for operators to Generate Revenues
Why NFV as a Service?

• Network Functions that can be “offloaded” by Enterprises
• Reducing the cost of network management / configuration
• Firewall, VPN, Guest WIFI, MPLS, Bandwidth.. All Virtualised

No Standardized
Protocols for NVF
For the Customer
• How to request NVF resources
from Third Parties?
• How to describe the request for
resources?
• How to compare offerings?
• How to know when to spin up /
down NFVs?
• Which functions can be virtualised?

No Standardized
Protocols for NVF
For the NFV Provider
• How to guarantee any SLA?
• How to cope with highly dynamic
demand for NFVs?
• How to spin up/down NFVs rapidly?
• How to combine NFV with Cloud
Computing?
• How to account for NFV usage?
• How to ensure secure NFV usage?
