What Is Software Defined Network (SDN)?
What Is OpenFlow?
“…In the SDN architecture, the control
and data planes are decoupled, network
intelligence and state are logically
centralized, and the underlying network
infrastructure is abstracted from the
applications…”
“…open standard that enables
researchers to run experimental
protocols in campus networks. Provides
standard hook for researchers to run
experiments, without exposing internal
working of vendor devices…”

What is OpenStack?
Opensource software for building
public and private Clouds; includes
Compute (Nova), Networking (Quantum)
and Storage (Swift) services.

What is Overlay Network?
Overlay network is created on existing
network infrastructure (physical and/or
virtual) using a network protocol. Examples
of overlay network protocol are: MPLS,
LISP, OTV and VXLAN

• Cisco continues to pursue broader strategy (Cisco ONE), which
includes SDN
- Programmatic device APIs
- Network overlay virtualization
- Network functional abstractions (controller & openflow for SDN)
Cisco’s portfolio already includes several key components of an SDN solution
• OpenFlow is a protocol, not an architecture
OpenFlow primarily define a protocol for packet forwarding
OpenFlow is not complete for production (e.g. lacks: high availability, security,
L3-forwarding model, management infrastructure, testing and certification
framework, hybrid deployment capability)
• Migration to SDN will be evolutionary
Cisco will take a use-case driven approach that draws on several key elements
of Cisco's product and technology portfolio
Cisco will in the near term engage with specific customers on OpenFlow as a
prototype technology
