You might also want to mention AMWA NMOS, which is increasingly used alongside SMPTE 2110 in setups like this. NMOS (Networked Media Open Specifications) defines open, vendor-neutral APIs for device discovery, registration, connection management, and control of IP media systems. In practice, it's what lets 2110 devices automatically find each other, advertise their streams, and be connected or reconfigured via software.

The specs are fully open source and developed in the open, with reference implementations available on GitHub (https://github.com/AMWA-TV)

The specs define REST API's, JSON schemas, certificate provisioning, and service discovery mechanisms (DNS-SD / mDNS), providing an open control framework for IP-based media systems.

> like why they use bundles of analog copper wire for audio instead of digital fiber

Good article. Got me to read the article because I was curious why...

nice to see an article from my industry! st2110 is such a complex standard which a lot of the hardware mentioned has been molded to deal with.

Fun to see.

PipeWire had some decent AES67 support for network audio. Some really fun interesting hardware already tested. Afaik no SMPTE 2110 (which is video) but I don't really know.

I know it's not the use case but I do wish compressed formats were more supported. Not really necessary for production, but these are sort of the only defacto broadly capable network protocols we have for AV, so it would expand the potential uses a lot IMO. There may be some very proprietary JPEG-XS compression, but generally the target seems to be uncompressed.
