Key SD-WAN Features
Enterprise customers are demanding more flexible, open, and cloud-based WAN technologies, rather than installing proprietary or specialized WAN technology that often involves expensive, fixed circuits, or proprietary hardware.
The software-defined wide-area network (SD-WAN or SDWAN) is a specific application of software-defined networking (SDN) technology applied to WAN connections such as broadband internet, 4G, LTE, or MPLS. It connects enterprise networks — including branch offices and data centers — over large geographic distances.
The main goal of SD-WAN technology is to deliver a business-class, secure and simple cloud-enabled WAN connection with as much open and software-based technology as possible. This can be used to deliver basic WAN connectivity, or it can be used for premium business services such as VPN, WAN optimization, and applications delivery control (ADC). The focus here is lowered costs, increased reliability, and enhanced security for an enterprise WAN ecosystem.
The providers that are offering legitimate SDN solutions are able to provide a key feature as it relates to performance. For example, let’s examine a scenario where you have your two internet connections. There is an application like hosted VoIP and a low-cost bandwidth solution like cable backed up with a DSL connection. Neither of those connections are bulletproof. A key feature functionality is the ability to adapt to performance of the environment in real-time. Look at latency with the cable and DSL along with jitter and packet loss as all three affect the voice quality. Good SDN solutions will be able to take those into account in real time and adapt a voice call as it relates to the real time performance of the network. When problematic connections arise, it could reroute to the secondary link without disrupting the call. All that is done without having to touch the box since it’s automated.
In a traditional router environment, you can load balance two connections as well as an automatic failover. But typically you will do that based upon hard downs. That will require manual swapping and restarting connections which cause interruptions. SD-WAN does all that without any perceived disruptions or manual servicing.
A bonus feature is the ability to alert. Set notifications to alert about an outage and gain visibility on who is doing what within your network environment.

Ever wonder how SDWAN really works? Watch in real time what happens when you pull the plug on your internet and have SDWAN maintain a hosted UC call uninterrupted. This simple demonstration shows only a small piece of what adopting SDWAN architecture can do for your voice and data network.
Comparison Of SDWAN Providers....
There are five major points that should be understood before diving into carrier comparisons.
- Replace high-cost MPLS/private bandwidth with low cost internet connections
- Respond in real time to network performance and route around issues
- Easy to deploy and maintain
- MPLS-like performance of real-time and important applications (QOS)
- Performance visibility and network monitoring
