2.3 SDN's impact on network management and operations

SDN revolutionizes network management by automating tasks and streamlining operations. It introduces centralized control, enabling faster configuration, dynamic resource allocation, and efficient service deployment. This shift aligns with the chapter's focus on comparing traditional networking to SDN architecture.

SDN's impact extends to monitoring and troubleshooting, offering real-time visibility and proactive management. It enhances network flexibility through features like intent-based networking and network slicing, showcasing SDN's advantages over traditional approaches discussed in the chapter.
