NDP leverages advanced technologies, including artificial intelligence and machine learning, to identify patterns, detect anomalies, and troubleshoot issues proactively.

Traditional Networking vs. Digital Network Architecture

Traditional networking and Digital Network Architecture represent fundamentally different approaches to network design, implementation, and management. The main difference lies in their underlying architecture and management strategies.

Hardware-Based vs. Software-Based Approach

Traditional networking relies on a hardware-based approach, where each device (routers, switches) is individually configured and managed through command-line interfaces or basic management tools. In contrast, Digital Network Architecture (DNA) employs a software-based approach, abstracting network functions from the underlying hardware, enabling greater flexibility and automation.

• The hardware-based approach creates operational complexity and increases the potential for configuration errors.
• DNA’s software-based approach enables greater flexibility, automation, and programmability.

Centralized vs. Distributed Control

Traditional networks operate with distributed control planes, where each network device makes forwarding decisions independently based on locally configured rules and protocols. DNA, however, implements centralized control through controllers like DNA Center, providing a single point of management for the entire network infrastructure.

• Centralized control enables consistent policy application and simplified troubleshooting.
• It allows for the management of network-wide changes from a single interface.
