Software-Defined Wide Area Network overview

The Internet has proven to be the global fabric that interconnects all things, as a result, networks need to provide more value than simply raw bandwidth. The ultimate goal is to eliminate or reduce the need for private WAN technologies like MPLS by making the WAN more responsive and less complex. Software-Defined Wide Area Network (SD-WAN) proposes exactly this.


SD-WAN is an alternative and more dynamic approach to designing and deploying enterprise WAN solutions - providing greater network visibility and control. It aims to replace traditional branch routers with appliances that use virtualisation, application-level policies and network overlays to make several Broadband Internet links behave like a dedicated managed circuit.


Here’s how SD-WAN can add value to your business:


Integrates with existing WAN architecture and improves network efficiency, agility and flexibility.
Provides improved network visibility and control of apps, and is fully scalable, configurable and cost-efficient.
Makes the WAN more service-centric, with monitoring and management of traffic focusing on delivery of apps.
Virtualises resources to provide accelerated service delivery, better performance and improved availability.


SD-WAN service components


1. 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.

2. 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.

3. 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.

4. Service Orchestrator

The Service Orchestrator provides the service management of the SD-WAN service lifecycle including service fulfilment, performance, control, assurance, usage, analytics, security and policy.

5. 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.
