Visiting back, SD-WAN  is an acronym for software-defined  networking  in a wide area network (WAN). SD-WAN simplifies the management and operation of a WAN by decoupling (separating) the networking hardware from its control mechanism -Wikipedia Since SD-WAN separates  network mechanism  (WAN architecture) from its control mechanism (Routing Protocols and decisions), the routing decisions for each request can be made intelligently. No longer does a data packet or an application request from the Branch office need to Travel Back to the data center for it to be routed. Intelligence is added at the branch office location itself so that traffic can be routed across the WAN for the highest performance and efficiency outputs. How does SD-WAN work? In a network infrastructure environment, there are two planes- the data plane and the control plane. In an SD-WAN environment, the two planes are separated. However, in the traditional model, The Data plane and the control pl

Suppose you want to connect with the internet, to the outside world. How is the networking capability leveraged? Through a Wide Area Network! In order to access the internet, any computing device needs to be connected to a WAN ( Wide Area Network). Whereas LANs (Local Area Networks) connect machines locally, WANs (Wide Area Networks) help machines communicate to the outside world. With the proliferation of the  cloud  environment, SD-WAN capabilities are becoming a necessity at many organizations. We will discuss the various capabilities of SD-WAN in this article series.

Traffic was routed among branch locations and data centers via their addresses on data packets through TCP or IP Protocol. Routers managed the work of distribution of data packet
