Software defined networks are used to address integration and automation challenges across the IT industry. For example, many companies are deploying SDN in order to programmatically control and automate both physical and virtual network environments.

Some of the examples that we've seen of challenges that folks are trying to address ... SDN started on the Stanford campus where a group within the computer science department was trying to take production network flows, redirect those flows to the computer science department, and do some academic research on them without filing trouble tickets to the operations team. That example turned into what are other ways that we can programmatically control and automate network traffic.

Some of the things that folks are trying to do now have evolved quite a bit from those early SDN discussions beyond just the campus slicing example that I mentioned earlier. A lot of what we're focusing on as a lot of the companies move to cloud-enabled environments, how do we do more system-level automation of the infrastructure. Not just the network infrastructure but of the compute and storage infrastructure as well. We're working with a lot of cloud builders and SAS companies who are essentially using SDN as a way to automate the network systems both across the physical environment as well as the virtual environment, and have that tied into their application automation environment.
