What is the meaning of the "AS" acronym that the paper uses (seemingly representing network providers)? I didn't see it explained anywhere and it's not ringing any bells with me…

AS refers to the Autonomous System. https://en.wikipedia.org/wiki/Autonomous_system_(Internet)

It's an IP routing concept. AS Numbers are used to refer to different networks (run by different ISPs and providers) on the internet.
