Network specialists herald the software-defined wide area network (SD-WAN) as the most significant advancement in corporate networks in years.

Here’s why: SD-WAN dynamically routes traffic among multiple connections based on the performance of each link and the priority of applications using the network.

Connections may include relatively expensive, high-performance MPLS VPN links, lower-cost dedicated internet access, or cheaper, “best efforts” business broadband service. Accordingly, SD-WAN dynamically optimizes connectivity cost and application performance. (More on that here.)

The US cable TV and broadband sector has undergone a major period of consolidation in the last six months, signaling big changes in the market’s DNA.

Case in point: Charter Communications completed takeovers of Time Warner Cable (TWC) and Bright House Networks in May this year, while the Amsterdam-based telecoms investment firm Altice finalized buyouts of Suddenlink and Cablevision in December 2015 and June 2016, respectively.

In Part II of TeleGeography's Mythbusters presentation at SubOptic 2016, Alan Mauldin busted five myths that ranged from whether capacity demand is doubling every two years to a quote from the movie Gravity that the destruction of a single satelite would lead to half of North America "losing their Facebook." In the concluding part of this series, Tim Stronge returns to the stage to take on myths about energy costs pushing decisions about content providers' data center locations, multiple parties building on the same route and "adult" content driving most Internet traffic.

While the potential benefits of incorporating software defined wide area networking (SD-WAN) are clear, there is no single migration path. At the WAN Summit New York, Intuit Principal Network Architect Manish Gupta offers lessons from his organization's experiences adopting SD-WAN and how they transformed their network architecture. Or in Gupta's own words: “I think we know why we’re moving there... But the question is: How are we getting there?”
