SD-WAN is now widely used as a core network approach within SASE and SDSA frameworks, leveraging internet-based connectivity alongside MPLS and wireless technologies to improve flexibility and coverage. While this brings clear benefits, it also introduces challenges such as complex routing across multiple paths, limited visibility, and reduced control over IP address management. Security is not significantly enhanced, and large-scale deployments can be difficult and time-consuming. Integrating a DDI solution helps address these issues by improving IP address control, simplifying network management, and enhancing overall efficiency and reliability in SD-WAN environments.
