I believe what is holding this back from becoming mainstream reality is that the cloud providers are building their own swaths of software solutions to run in x86 CPU's, and that code does not make it into the wild to see what else can be done with it. So the general community keeps messing about with flavour-of-the-year-SDN-thingy, until we realize it doesn't work and we move on to yet-another concoction. I believe if the cloud boys & girls shared more of that code so the network operators can see what to do with it on white boxes fitted with Broadcom (or equivalent), the rate of "simplification" could accelerate. > > Next wave will (are) probably photonics, moving further and further into > direct feature capabilities without influencing speed-down to tackle specific > feature in silicon.

I saw a preso from a major cloud provider (their main cloud product rhymes with the number of days in a year) around that back in San Diego, 2018, at some DWDM conference. It was scary for the Transport vendors. That was nearly 3 years ago. It wouldn't surprise me if it's now an in-house solution.
