An In-Depth Review of the Fundamentals and Functions of SD-WAN Technology

A software-defined WAN is a logical development in WAN optimization. It is a technology that was built from the understanding of private WAN links, and maximizing them for traditional or standard traffic patterns. The SD-WAN technology takes this process a step further by tapping into all available resources that include affordable internet services to achieve the largest operation network. This technology is still on the rise, but with its undeniable great potential, its wide growth is evident.

Great New Demands to SD-WAN Technology

The relevance of the SD-WAN couldn’t be denied that even well-established businesses have avail for this technology. An IT director of a well-known electronics company has made a good statement about the SD-WAN technology as a good alternative from other WAN protocols such as MPLS. Over the past few years, people and organizations have spent a lot of money for the aforementioned networking protocol. You can avoid spending a huge amount of money through this cost-effective technology, the SD WAN.

With the vastness innovations in computing and software application services, the traditional or standard WAN optimization is less evident over the past few years due to the overwhelming traffic flow that comes from various branch offices to the cloud or other software application services online, rather than to the data center.

The software-defined wide area network is not just all about optimizing or maximizing the operation of the packet delivery for storage or branch connectivity. SD-WAN technology is rather more about redefining the wide area network or WAN to represent a network that doesn’t singularly dependent on a costly collection of the MPLS links. The software-defined wide area network would productively choose from a more cost-efficient diversity of various public internet connections and private links.

The key function of the SD-WAN in the networking operation is collecting network links to select which is the most convenient, cost-effective, and cheaper than the other networking protocol technologies.

Since time immemorial, network engineers have set up networking tunnels to facilitate routing, wherein when you want to reroute traffic through a much more affordable network tunnel, you build a network tunnel. This was the previous networking operations, but the network tunnels then were static and were formed by network engineers to facilitate the routing operations.

However, with software-defined wide area network, the routes are not static, and the software application services are in full control or in charge.
