SDN Value Proposition

• Lower the cost of expensive network components
• Fully utilize existing equipment (virtual
  networks, route traffic to network components,
  etc).
• Create virtual routers, firewalls, IP VPNs, load
  balancers, network monitoring, etc,

Improve CAPEX

• Provision network at a larger scale (system
  level)
• Network operations are more self-serve and
  automated
• Adjust traffic flows dynamically to reduce cost
• Example Reduce power, Fully utilize WAN links

Lower OPEX

• Quickly/automatically add/remove/changes
• Examples Provision network around security
  services based on new or time based workloads or
  VM movement Segment network to provide highly
  secure multi-tenant services

Network Agility

Open Networking Foundation (ONF)

• Open Networking Foundation (ONF) is a user-driven
  organization dedicated to the promotion and
  adoption of Software-Defined Networking (SDN)
  through open standards development.
• ONF emphasizes an open, collaborative development
  process that is driven from the end-user
  perspective.
• The OpenFlow Standard is the first SDN standard
  and a vital element of an open software-defined
  network architecture.
• Our signature accomplishment to date is
  introducing the OpenFlow Standard, which enables
  remote programming of the forwarding plane.
• Today, our working groups continue to analyze SDN
  requirements, evolve the OpenFlow Standard to
  address the needs of commercial deployments, and
  research new standards to expand SDN benefits.
