Efficiency
Source Extreme Networks, 2013
8SDN 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

17Open 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.
