Key SD-WAN Features

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.

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
  • h1
  • Easy to deploy and maintain
  • MPLS-like performance of real-time and important applications (QOS)
  • Performance visibility and network monitoring
The prioritization should be customizable to the types of traffic that need to take precedence in your environment, and SD WAN is a great option. The carrier options available though are going to have different added value that will make each solution better fits for certain types of customer needs.
