What is SD-Access?

SD-Access is a Cisco solution that extends their Digital Network Architecture (DNA) to campus networks through intent-based policy, automation and assurance. It offers organizations a more simplified approach for building such networks, by managing everything from security to user access policy.

SD-Access provides the following features:

  • Network visibility

  • Network management

  • End-to-end segmentation for devices and users

  • Automation of tasks related to network policy enforcement

  • Adaptive learning

  • Proactive responses to breaches

The DNA Center Controller lies at the heart of SD-Access and manages the network. Through a single platform, it includes applications that can help you with network design and security, configuring policies and creating virtual networks.

A SD-Access fabric includes four types of nodes. A border node connects with networks outside the fabric. An edge node connects devices to the fabric. Control plane nodes manage traffic between the edge nodes. Finally, intermediate nodes route IP traffic between the border and edge nodes.
