6. Limitations of Current Networks
 No control plane abstraction for the whole network!
 It’s like old times – when there was no OS…

7. Limitations of Current Networks
 Low number of network engineers
 In 2014, the median network device to engineer ratio was 37 to 1.
 In 2015, that number was 59 devices per engineer, a jump of 60% in a single year.

8. Limitations of Current Networks
 Vendor Lock-in

9. Limitations of Current Networks
 Old ways to configure a network

12. Software Defined
 Moves traditional computing functions and processes
from hardware to software-based approaches.
 SD changes traditional hardware architectures from
a hardware model to a software model.

13. Software Defined Approaches
 Software Defined Radio
 SDR Software Defined Compute (Virtualization)
 Software Defined Networking- SDN
 Software Defined Storage
 SDS Software Defined Data Center- SDDC
 Software Defined Everything

14. Software Defined Networking
 Software Defined Networking (SDN) involves
moving networking functions such as routing,
switching, and security from networking hardware to
software based approach.
 Control is decoupled from hardware and given to
a software application called a controller.
