3. (per Wikipedia definition)
What is SDN?
(per Wikipedia definition)
Software Defined Networking (SDN) is an approach to building computer networks that separates and abstracts elements of these systems

4. Different Execution Paths
“A way to optimize link utilization in my network enhanced, application driven routing”
“An open solution for customized flow forwarding control in and between Data Centers”
“An open solution for VM mobility in the Data-Center”
“A platform for developing new control planes”
“Develop solutions at software speeds: I don’t want to work with my network vendor or go through lengthy standardization.”
“A way to reduce the CAPEX of my network and leverage commodity switches”
“A means to get assured quality of experience for my cloud service offerings”
“A solution to build a very large scale layer-2 network”
“A means to do traffic engineering without MPLS”
Diverse Drivers
Common Concepts
“A solution to build virtual topologies with optimum multicast forwarding behavior”
Different Execution Paths
“A way to optimize broadcast TV delivery by optimizing cache placement and cache selection”
“A way to build my own security/encryption solution”
“A means to scale my fixed/mobile gateways and optimize their placement”
“A way to configure my entire network as a whole rather than individual devices”
“A solution to get a global view of the network – topology and state”
“A way to distribute policy/intent, e.g. for DDoS prevention, in the network”

13. WHY SDN? SIMPLICITY SPEED PROGRAMMABILITY
We have sessions on Tuesday covering each aspect of Cisco ONE strategy.  The onePK Product manager will present the real world use cases that use onePK device APIs. We will hear the XNC controller team providing data center use cases harnessing XNC. We have a deep dive session on Virtual Overlays. In addition to that we have 5 hands-on lab sessions starting Wednesday each for onePK and XNC”
These are the sessions that deep dive in to aspects of Cisco ONE strategy
1)      Software Architecture for Next-Gen Data Center (90min) Monday 1:45:  
2)      Cisco onePK in the Data Center: Real World Use Cases (60min) Tuesday 8:00A
