The Cisco IT network services team views network programmability—the broader category that includes SDN, or Software-Defined Networking—as one of our top priorities.
To clarify terms, SDN is a network architecture that decouples the control plane (that is, the building of a routing table) from the data plane, moving the control plane to a software-based centralized controller. In Cisco IT, we see the real value of SDN as enabling network programmability. Network programmability requires two capabilities: harvesting information from network devices, and automatically pushing out new configurations in response to dynamic network conditions or service-provisioning requests.
We’re in the early stages of weaving network programmability into Cisco IT programs. So far, we’ve identified five internal use cases. Read More »
