2. Customer Networking Requirements
v Users to securely access business application via the internet through
firewall.
v Load balancing between the multiple data servers for business continuity.
v Securing the data from the external threats.
v Scalability for future expansion.
v CAPex, TCO reduction using minimal hardware.
v Simple flatter architecture, easy to manage with automated operations.

5. Software Defined Application Delivery Network (SD-ADN)
Value Propositions:
1) Low CAPEx/OPEx with soft firewalling, load balancing and packet forwarding.
2) Centralised control and virtualization of the entire network.
3) Facilitate faster deployments and troubleshooting.
4) Path optimization, better fault detection and resolution.
5) Simpler architecture with automated operations.
6) Increased performance and stability.
7) Innovation at software speed.
8) Application aware networking

6. Costing Estimation
Conclusion
• Approx. ~ 50-70 % Reduction in CAPex using SDN.
• Approx. ~ 60-80 % Reduction in Opex using SDN.
