This document discusses intent-based networking powered by Cisco's Digital Network Architecture. It describes why intent-based networking is needed due to the limitations of traditional networks in handling more users, devices, and complex configurations. Cisco's intent-based networking solution uses Cisco DNA Center and network devices to deliver automation, assurance, and security through the use of intent, context, analytics, and machine learning. It provides benefits such as reduced operating costs, improved issue resolution times, and lower security breach impact.
