What if I told you that SD-WAN has a scaling problem? Tunnels. If you’ve dug into SD-WAN architecture, you know that most (not all, but most) SD-WAN solutions are an overlay fabric, and by overlay, I mean tunnels. Tunnels on top of the physical LAN and WAN circuits connecting the infrastructure together.
Tunnels don’t come for free. There’s encapsulation and decapsulation that has to happen for every packet. There’s encryption with all of the authentication and math implied. And of course, there’s the performance monitoring of the tunnel fabric.
Now, our sponsor today isn’t suggesting that all of what the networking industry has built in SD-WAN over the last decade goes away. But the team behind Graphiant knows SD-WAN well, and learned some things building what we might call “SD-WAN gen 1.” They’ve taken those lessons to re-think what was wrong with SD-WAN the first time around to develop an “SD-WAN gen 2.”
Joining us for our discussion today is Ali Shaikh. Ali is the Chief Product Officer at Graphiant and knows how the product works at a deep level.
* How tunnels add complexity to SD-WAN
* Graphiant’s Network as a Service (NaaS) approach and how it works
