do you mean 'uses'?
This comment has been downvoted, but I don‘t understand why. The phrase “user different pipes, because [magic]" is unclear to me as well.
(Didn't downvote, but I did spent a good minute trying to parse the problem.)

Also, the reason many don't use TCP is that while it guarantees ordering and packet arrival people completely forget that it's doing that by adding an indeterminate amount of latency. It's not some "packets arrive perfectly / user different pipes, because [magic]" solution.
I would love to learn more about this. How did the authentication system work? How difficult was it to brute force? Does it simply involve a master key creating individual subkeys? Is it RSA?

On the other hand, to misquote Philip Greenspun, any sufficiently complicated UDP-based protocol contains an ad-hoc, informally-specified, bug-ridden, slow implementation of half of TCP.

Also this is a good paper (10 years old) on DOOM 3's networking:

- hybrid reliable and unreliable, ordered and unordered delivery semantics
- automatic MTU fragmenting, to avoid router fragmentation
- ordered multi-channel multiplexing
Unfortunately SCTP never took off, but it is the data channel protocol for WebRTC, which uniquely positions WebRTC as a nice platform for game networking in the browser. (However, the stack must be implemented in user space since it is SCTP over DTLS over UDP.)
We are working on a WebRTC based game networking server for Social Mixed Reality at Mozilla which uses the Janus WebRTC gateway as the connection manager, our initial work can be found here:

Our initial SFU plugin for Janus already out of the box makes it easy to set it up as a dumb game networking server that just relays messages between peers, but our plan is to turn it into a connection manager in front of an OTP service that provides full authoritative game networking services.
It is a 17-year-old article. Did the fundamentals stayed the same or has there been any significant paradigm shifts in how game networking is done?
