Top 10 Things you Should Know About SD-WAN

So how do you implement SD-WAN?

Software-defined wide area networking (SD-WAN) provides many benefits over traditional wide area networking (WAN) architectures, leading businesses to wonder how they would go about implementing SD-WAN.

Since virtually every business already has remote locations with legacy WAN infrastructure in place (routers), SD-WAN is often implemented in a non-disruptive way that first augments the existing legacy WAN hardware.  Once the business is comfortable with SD-WAN, the legacy WAN hardware can be removed.

An example of such an implementation is as follows:

  • Business decides to deploy SD-WAN
  • A small pilot is performed in some number of sites. Devices are shipped to each of those sites
  • The SD-WAN devices are deployed in-line between the WAN router and the LAN switch
  • Once the business is comfortable with the SD-WAN solution, legacy WAN gear is removed

From there, a staged roll-out plan is often defined to migrate each location from legacy WAN to SD-WAN.

SD-WAN can help businesses improve application performance, integrate the cloud, reduce branch and WAN hardware and operational costs, and enable new levels of agility and automation that were previously not possible.
