SD-WAN enables the kind of connectivity needed in today’s cloud era. It creates software-defined overlays, which are abstracted from the transport underlay. With these overlays, it is easier for a user located anywhere to reach services hosted anywhere.

However, overlay-based SD-WAN comes with one big caveat: dependence on tunnels. Although these tunnels can make the creation of overlays easier, there are issues:

  • The network transport is heavyweight and less optimized
  • Fragmentation is introduced
  • Scalability and security are negatively impacted

In this research report, learn about the benefits and the option of tunnel-free SD-WAN.
