The benefits and the option of tunnel-free SD-WAN
Tunnel-Based versus Tunnel-Free SD-WAN
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.
