Imagine a service provider that allows you to provision 100GE point-to-point circuit between any two of their POPs through a web site and delivers in seconds (assuming you’ve already solved the physical connectivity problem). That’s the whole idea of SDN, right? Only not so many providers got there yet.
Now imagine they’re doing something really cool behind the scenes like using VXLAN with EVPN on the edges and MPLS/TE in the core (but only when needed) combined with leading-edge optical technologies. Welcome to PacketFabric.
