SD-WAN service components
Software-Defined Wide Area Network (SD-WAN) Edge
The SD-WAN Edge creates and terminates secured and encrypted tunnels over different types of wired or wireless underlay networks such as Broadband Internet, WiFi and LTE as well as DIA and MPLS core networks. The SD-WAN Edge also performs application-based QoS and security policy enforcement, application forwarding over one or more WAN connections and QoS performance measurements over each WAN to determine optimal path selection.
Software-Defined Wide Area Network (SD-WAN) Gateway
The SD-WAN Gateway is a special instance of an SD WAN Edge that also enables sites interconnected via the SD-WAN to connect to other sites interconnected via alternative VPN technologies.
Software-Defined Wide Area Network (SD-WAN) Controller
This provides physical or virtual device management for all SD-WAN Edges and SD-WAN Gateways associated with the controller. The controller is used for configuration and activation, IP address management and pushing down policies onto SD-WAN Edges and SD-WAN Gateways.
The Service Orchestrator provides the service management of the SD-WAN service lifecycle including service fulfilment, performance, control, assurance, usage, analytics, security and policy.
Customer Web Portal
After the SD-WAN service is activated, the Customer Web Portal communicates with the Service Orchestrator for SD-WAN service modifications such as setting up different QoS, security and business policies based on the user’s role.
