Top 10 Things you Should Know About SD-WAN

How do you configure SD-WAN?

Software-defined wide area networking (SD-WAN) is fundamentally different than traditional wide area networking (WAN).  In traditional WAN, you have to configure routers and other networking devices at each location, along with a series of packet-centric features and routing protocols to ensure connectivity amongst your sites.

With SD-WAN, devices are managed by a centralized controller, which is responsible for propagating configuration changes to all devices in the network and collecting monitoring statistics.

The typical workflow for configuring SD-WAN is:

  • Pre-configure branch devices to be able to access the network
  • Configure data center devices to access the network
  • Login to the controller, and assign devices to sites
  • Define your application policies

And voila!  The configuration automatically propagates throughout the network.  This is far simpler than traditional WAN which often requires one or more devices in each site.

CloudGenix AppFabric makes it even easier by aligning the definition of WAN policy with business policy.  This means that, when your CIO says “Office 365 and voice calls should have gold service”, the policy you implement is exactly that – not a mish-mash of esoteric networking rules, access control lists, policy routes, and complicated QoS configurations.

So how do you implement SD-WAN?
