QoS and Policy, the real reason for SD-WAN
Why would someone buy an SD-WAN solution? Taking the painful management aspect of traditional routers out of the equation, the other major point is that of the unreliability of the WAN links. Sure, everyone wants Direct Internet Access, bring-your-own-bandwidth, but do we really trust what we get? When someone complains their apps are not working well, do we know why that is? Surely it can't be the WiFi again!
In a previous video (found here), I have given an overview of DMPO (Dynamic MultiPath Optimisation), the umbrella of technologies that made VeloCloud one of the most performant solutions on the market.
In this video I wanted to focus on how QoS works, and how you, as an admin, are able to express your business intent while creating policies. And you don't even have to read a 500 page book about it.
