There are several tools out, some of them open source based:

jacktrip (https://ccrma.stanford.edu/software/jacktrip/)

soundjack (https://soundjack.eu/, closed source)

jamulus (http://llcon.sourceforge.net/)

Just to name a few.

We developed our own system based on zita-njbridge and some self-written
network managing tools, which we use almost every day:

The delay which can be achieved (with all of the systems - the
underlying network is the most critical factor) will be in the order of
30-80 ms between musicians (one way). 30-50 ms feels more or less ok, if
it is more you need to play actively before the time.

Best,

Giso
