AT&T Successfully Deploys dis-aggregated core routing platform.

Curious what you guys think about this blog post from AT&T's new supplier DriveNets... https://drivenets.com/news-and-events/press-release/att-deploys-drivenets-network-cloud-in-their-next-gen-core/

Seems like a pretty big shift where they are starting to run a lot of the routing functionality on x86 servers? Curious if this is a big deal or just a really good blog post out of the DriveNets marketing team? It doesn't' say how the new core differs from the old, but I am assuming they were previously running hardware from a vendor like Cisco or Juniper and now they are running things on white-boxes and x86 servers?

I mostly only really followed the major cloud driven open compute projects like SONiC/SAI, so I am kind of surprised to see a telco like AT&T push something that seems similar in routing.
