What is SDN?

Customer Insights over the last 12 months

Research/Academia

• ExperimentalOpenFlow/SDN components for production networks

Massively Scalable

Data Center

• Customize with Programmatic APIs to provide deep insight into network traffic

Cloud

• Automated provisioning & programmable overlay, OpenStack

Service Providers

• Policy-based control & analytics to optimize and monetize service delivery

Enterprise

• Virtual workloads, VDI, Orchestration of security profiles

Diverse Programmability Requirements Across SegmentsMost Requirements are for Automation and Programmability
