The Evolution of Optimized Wide Area Network (WAN) – SD-WAN and WAN Innovations

Over the course of technological advancement, there have been a series of continuous development, optimization, and innovation that had been made. The modifications, transformations, and discoveries in the advancement of technology are still ongoing, and currently monitored, enhanced and developed. Man’s brains definitely want to further explore the endless possibilities of the optimum workability and functionality of the technological advancement.

The evolution of the internet all started with a single desktop computer to connecting consoles together, and now, it has become a full-blown worldwide network. In just a short span of time, people across the globe are connected real-time.

Now, the evolution of optimizing the capabilities of the Wide Area Network or WAN continues with the growth of SD-WAN and Cloud WAN.

An Overview of the Wide Area Network or WAN

What is a wide area network or WAN exactly? It is a computer network or telecommunications network that expands its connection across a wide and massive geographical distance. It interconnects multiple local area networks within different geographical distance and broadness through the routers or other multi-functional equipment.

In a group of organizations, the wide area network or WAN may involve connections to a company’s main location, branches, and other facilities. The wide area network connection between organizations allows each user in the group to share access to various work applications, services, and other centralized located resources.

This method of networking makes all business processing operations across the globe easier and faster without the need to install various other equipment facilities just to make the connections. Hence, the wide area network has greatly helped in making things easier for businesses and other individuals to communicate and work together simultaneously.

What is a Software-Defined WAN?

A software-defined WAN is a kind of networking that simplifies the overall management functionalities and operations of the wide area network. It allows companies to build higher performance or optimized wide area network through a lower cost or cost-effective internet access and flexibility. Thus, SD-WAN technology allows enterprises to entirely or partly replace more lucrative private WAN connection technologies. Take advantage of SD-WAN solutions to build a truly agile and cost-effective network.

Moreover, SD-WAN technology allows a network manager to separate a number of different connections and have them function or work similar to a virtual overlay network by using a path selection and comprehensive traffic engineering to strengthen the link to its maximum operation. Overall, the ultimate goal of this technology is to remove the requirement for expensive WAN links through achieving a comparable level of performance and reliability in operation with several internet links.

The Essentials of WAN Innovations

Comprehensive innovations of the wide area network were developed and continuously ongoing due to the intentions of optimizing worldwide connections across the extensive geographical distance, and at the same, lessening the cost and making the operations more reliable and flexible.
