SDN separates network control logic from physical devices like routers and switches. This allows for more flexible traffic management to address the increasing network traffic from mobile devices, cloud computing, and social media. SDN provides programmability, automation, and virtualization to help manage complex global networks and respond quickly to changing business needs and traffic patterns. It transforms networks into agile, flexible, and cost-effective systems well-suited for today's high bandwidth dynamic environments.

1. Role Of Software Defined
Networking (SDN) in Present
Complex Network Arena
Presented by
Ravi Namboori

2. Definition:
Software Defined Networking, SDN is an innovative
paradigm in computer networking that separates
network logic control from off-device computer
resources such as physical routers and switches.

3. Need……..
• In the present digital arena, the deluge of data from
social media, cloud computing and mobile devices is
driving global networks towards saturation.
• Network limitations need to be addressed with
automation and virtualization that significantly transform
the storage and computing practices.

4. Network Traffic Patterns……..
• Empowers network managers to write SDN programs
themselves and handle configuration, managing, securing
and optimizing network resources.
• SDN evolved out of need of managing complex global
networks, rapidly changing network traffic patterns
demands flexible traffic management solutions.

5. Value addition….
• Enterprises opt for SDN to empower their network
administrators and engineers to quickly respond to constantly
changing business requirements.
• SDN enables enterprises to achieve network virtualization,
functional separation and automation.
• Drives innovation in to enterprise networks by virtualizing the
computing and storages options and giving organizations an
edge in effectively controlling their complex networks.

6. Revolutionizing………
• SDN transforms the conventional datacenters in to
virtualized environments that offers advanced computing
and storage capabilities.

7. Agile, flexible……
• SDN architecture is agile, flexible, dynamic, adaptable,
manageable and cost effective making it best fit for current
high bandwidth and dynamics network systems.
• SDN brings business agility by enabling network
administrators dynamically control traffic flow in networks as
per changing needs.

8. Control OpEx and CapEx……
• Pay-as-you-grow business model of SDN helps
businesses by limiting their spending on purpose-built
network hardware.
• SDN brings extensive programmability capabilities
enabling administrators to easily design, deploy, manage
and scale networks.

9. Use cases……….
Today SDN is significantly benefiting network carriers, service
providers, cloud providers, datacenters and enterprises
 Cloud and Datacenters: SDN gives network virtualization capability
that in turn enables faster turn-around times and optimized
resource utilization.
 SDN brings enhanced network monitoring and access control
capabilities in to enterprises environments.
