“Will OpenFlow commoditize networks? Impact Cisco margins?”—Several media publications, Bloggers
“Google revamps networks with OpenFlow”—ZDnet
Headlines
“Hype around SDN/OpenFlow getting way out of Control. Where have I seen this before…” —Ethereal mind, Blogger
“.We share a more pragmatic view, noting Cisco (for example) is likely to view SDN as a TAM expansion opportunity…” —Deutsche Bank
Research note, Wired, April 2012
“SDN needs a bigger definition”—Lippis report, 2012

Basic Definitions
What Is Software Defined Network (SDN)?
“…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…”
Source: www.opennetworking.org
What is OpenStack?
Opensource software for building public and private Clouds; includes Compute (Nova), Networking (Quantum) and Storage (Swift) services.
Source: www.openstack.org
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
What Is OpenFlow?
“…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…”

Cisco Perspective on SDN• 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 architectureOpenFlow 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 evolutionaryCisco 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
