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

Costing Estimation

Conclusion

•  Approx. ~ 50-70 % Reduction in CAPex using SDN.

•  Approx. ~ 60-80 % Reduction in Opex using SDN.
