What is SD-WAN?

A wide area network (WAN) might be used to connect branch offices to a central corporate network or to connect data centers separated by distance. In the past, these WAN connections often used tech that required special proprietary hardware. The SD-WAN movement seeks to move more of the network control into the cloud using a software approach.

Instead of bringing in an MPLS network into a branch location, customers can bring in two diverse internet connections. One is delivered on a cable modem,and the secondary a 4G router. In an SDN environment, a router is placed on the edge to provide a couple of features: we took a holistic approach and work with all the major SDWAN Vendors like VERSA, PALO ALTO, VELOCLOUD, ARYAKA, ADAPTIVE NETWORKS AND CATO.

This gives you far better edge to try any flavor of SDWAN and our Solutions Engineers can help with design and implementation of these cutting edge solutions.

  • Brings together the two connections
  • Load balancing
  • Proactive analysis of what is happening on that network
  • Creates the ability to do a VPN for office Internet connectivity to connect branches to headquarters
  • Because it is internet based, traffic that is destined for the internet can hop off right there

By application and by destination, this software can make intelligent routing decisions. Thus, if you have traffic destined for Office 365, it will decide if the cable or the 4G path is best, based on who has the best peering and who is the closest.

Voice and video can be prioritized whether outgoing or incoming.

You can create a quality of service policy on both sides giving you end to end performance control that you would expect. So yes, you can get the performance of an MPLS solution with an SDN WAN solution even though it’s over an internet connection. Internet service is readily available and very cost effective as opposed to MPLS environments.


With voice or IP communications, the ability to prioritize traffic is important. An SDN router keeps calls up and functioning in the event of any congestion, even Internet-based congestion. The router will duplicate the voice traffic and keep a secondary stream ready to go, so if it degrades while flowing on the primary connection, it will instantaneously flow over to the secondary connection and keep the call alive.
