What Is SD-WAN?
Many companies and technologists are asking, “What is SD-WAN?” SD-WAN is a new approach to an age-old problem – the need for robust, high QoS (Quality of Service) connections to mission-critical databases and infrastructure through a Wide Area Network (WAN).
In the past, traditionally defined WAN structures relied almost entirely on costly, privately rented MPLS lines, or other dedicated broadband infrastructure. And while these WAN structures did offer great reliability and good QoS, they were often incredibly expensive – and given the need for peak performance, the rented lines were almost always overprovisioned.
Companies would rent far more bandwidth than they needed on a day-to-day basis to ensure that they would have the bandwidth they needed at peak hours and during large data transfers. Obviously, this is quite wasteful – paying for something you don’t need 95% of the time is a massive waste of overhead.
SD-WAN Defined – The New Face of WAN Infrastructure.
Conceptually, SD-WAN is simple. Imagine that each of your network connections is separated – your MPLS is separated from your broadband connection, which is separated from your backup fiber connection, which is separated from your emergency LTE connections. A traditional WAN would use each one of these connections individually.
Using advanced technology and proprietary routing software, SD-WAN does the opposite – it brings each disparate connection together to create a robust, highly available WAN infrastructure that is much more than the sum of its parts.
This is achieved by using specialized routing software that analyzes each piece of web traffic and routes it to the appropriate connection – high QoS traffic like important video calls, data transfers, and cloud/offsite infrastructure requests are routed through priority network lanes like rented lines, while less important data transfers, web traffic, and other information is routed through traditional broadband lines.
What are the Advantages of SD-WAN?
There are three primary reasons you should be interested in a software-defined SD-WAN.
- Lower Costs – SD-WAN can help ensure maximum network connectivity while reducing the bandwidth required for costly, private lines. This is because instead of requiring overprovisioning, SD-WAN can prioritize important data automatically, ensuring that your most important data is always routed on your private lines, and reducing the need for bandwidth that is rarely used.

- Increased Efficiency – By bundling all of your disparate network connections together, SD-WAN systems can increase the efficiency of your day-to-day network use by quite a bit – overtaxed lines can have traffic rerouted, which allows your end-users to do more without bogging down your network.
- Expandability When You Need It – It’s easy to expand an SD-WAN network – new lines can be installed and usable quickly and efficiently, allowing you to easily expand your WAN when you are growing and need increased capacity, or if you’re moving your on-premises infrastructure to the cloud.
