What is the Cisco® Digital Network Architecture (Cisco DNA)?
The Cisco Digital Network Architecture (Cisco DNA) is Cisco’s architecture for enterprise networks – across the campus, branch, WAN, and extended enterprise. It provides an open, extensible, and software-driven approach that makes the network simpler to manage and more agile and responsive to business needs. Cisco DNA is an intelligent system that encompasses policy, automation, analytics, and open platform capabilities to deliver on all required aspects of an intent-based network.
What is the difference between Software-Defined Networking (SDN) and Cisco DNA? How do they relate to each other?
Cisco DNA allows IT to move beyond SDN and transcend the automation-focused network technologies that make up SDN. Cisco DNA uses a holistic systems approach to align the network to business intent. This approach combines automation with translation, policy, and assurance capabilities. Through its intent-based networking principles, Cisco DNA provides a way to make network services effective and agile as well as easy to use in an enterprise architecture journey to digital transformation. It is an architecture that includes ready-to-use applications as well as easily consumable APIs.
