The SD-WAN Controller is a core component of any SD-WAN solution and is vital in the implementation of new capabilities, working to provide basic and advanced features.
The SD-WAN Controller is a core network component providing physical or virtual device management for all SD-WAN Edges and SD-WAN Gateways associated with the controller. It is vital in the implementation of new capabilities.
The SD-WAN Controller maintains connections to all SD-WAN Edges and SD-WAN Gateways to identify the operational state of SD-WAN tunnels across different WANs and retrieve QoS performance metrics for each SD-WAN tunnel. These metrics are used by the Service Orchestrator.
