Software designed wireless area network is a virtual architecture or a bridge that connects the end-user to the application directly, by directing the incoming traffic as per requests. SD-WAN is a simple bridge that can be constructed between the end-user and the application which is requested, by directing all the end-user traffic into requested application streams.

It uses a centralized controlled function to establish segregation between different data requests, and then direct those traffic based on data requests, directly to the application itself. Dead on many components of SD-WAN and we shall discuss all of them in detail, in this article.

The architecture of SD-WAN:-

The problem with traditional wireless area networks was that they were never designed to handle the incoming traffic from the cloud itself.

They were based on conventional routers, which used to backhaul the traffic incoming from the end-user, and if there was more traffic from the user, then it would hang up or cause a delay from transmitting it from headquarters or main centres.

Now, since the software designed wireless area networks have been discovered, there has been no such problem of any delay, relating to the productivity of end-users, as it would not delay the traffic incoming to directed directly to the applications. This new software architecture can directly transmit user data from the end-user to the applications and can be used by all major applications such as Workday, Dropbox, Microsoft office.

Components of SD-WAN:-

SD-WAN Components are usually based on different types of SD-WANs as there are many available in the market. However, there are three basic components that are present in almost every SD-WAN:-

  1. The edge
  2. The controller
  3. The orchestrator.
  1. The edge:- The edges are where the endpoints of the software designed wireless area networks are located, and they can be routers, data offices, cloud services, etc.
  2. The controller:- The controller decides the policies for the orchestrator, and segregates the traffic from the end-user. The controller is the most important function inside this software design network, as it lets the operator see from a single pane of glass.
  3. The orchestrator:- The orchestrator is like the police department of the state. The orchestrator looks over the incoming graphic and applies all the rules and regulations, traffic protocols, policies, company insurance, security units, etc. given by the operator to the incoming traffic.

There are three main basic types of architecture present inside a software designed wireless area network, and there are three more SD WAN components:-

  1. Cloud-enabled backbone.
  2. Cloud-enabled.
  3. On-premises.
