Getting to know the SD-WAN infrastructure

The Software Design Network is moving enterprises forward. With automated operations, it has become easy to create these networks and manage them. Additionally, monitoring these systems has also become a walk in the park. But what is the system made of? The Software Design Wide Area Network sd-wan infrastructure is complex.

Components of the SD-WAN network

The SD-WAN infrastructure is made up of many components. They include; SD-WAN Edge, SD-WAN Gateway, SD-WAN Orchestrator, and SD-WAN Controller. These four components make the SD-WAN network what it is, with all its outstanding performance and efficiency.


This is a single, physical or virtual network placed at the enterprise’s branch office site, public and private cloud platforms, and the data center.

SD-WAN Gateway

This is meant to give access to the SD-WAN network service so that the distance between the cloud-based services and the system or user is shortened. It also works to minimize interruptions to the lowest levels possible. When made to stay away from the headquarters in the cloud, the sd-wan Gateway also helps reduce the headquarters’ traffic. A network of gateways can be included in the service or set up by the organization.


SD-WAN Orchestrator

This is a web management tool used for managing the SD-WAN. It enables the user to configure, provision, and carry out other functions while operating the network. It also permits the central implementation of the policies and priorities of an organization, thereby simplifying the application of traffic management.

SD-WAN Controller

It is the main component of the SD-WAN. The SD-WAN Controller is based on the control plans, templates, and inventories. It enables the user to configure the daily network operations easily. The process has guided steps included in the component’s graphical interface, which is user-friendly. The process doesn’t require technical CLI knowledge.

This component can be placed in an SD-WAN Orchestrator or Gateway. It is the primary function to forward application flows decisions. This enables the Controller to run requests and traffic during implementation smoothly. There are predefined parameters that determine how the Controller routes traffic. The parameters include; the organization’s policies, availability of requests, server load, etc.
