SOFTWARE DEFINED NETWORKS
( SDN)
NETWORKING BUSINESS CHALLENGES
Configuration
Features
Software
Packaging
Reliability
Overly complex,
manual, operationally
expensive.
Slow to respond to
business requests
Too hard to deploy
Inflexible, difficult
to scale
Below expectations
WHY DO WE NEED SDN?
Static Networks
Manual Policies
Monolithic Network
Services
Essential
Applications
Must respond dynamically
based on Business Policy
Must be automated to
reduce personnel cost
Must dynamically scale
independent of
network devices
Must be developed within
the network to deliver
business results
