Question: any thoughts on reliable UDP or QUIC? And QoS?

[jaredthirsk]

(I would post this as a discussion but it doesn't seem to be enabled for this repo.)

My understanding is most action games historically prefer some sort of reliable UDP, instead of TCP, because if packets are lost in a TCP connection, it has a head of line blocking problem which slows things down.

Is there any desire from Cysharp to consider this sort of functionality?

• reliable UDP or QUIC support
• Quality of Service: choosing a delivery mode (perhaps as an optional parameter on MagicOnion's .Connect()): at least once, at most once, exactly once

Note that there is a Microsoft QUIC implementation exposed to C# here:
https://github.com/microsoft/msquic
https://en.wikipedia.org/wiki/QUIC

[Edit: maybe I should be looking at this instead? https://github.com/RevenantX/LiteNetLib]

Suggested course of action:

1. Say "no", there are no plans for QUIC or reliable UDP (or yes)
2. Close this issue

I looked at this more, and I wonder if one ideal approach would be to put MagicOnion's RPC over LiteNetLib (or similar) as the transport.

It looks like the transport might be able to be swapped out, but after a bit of looking I couldn't quite figure out how to do it yet.

Has anyone else thought about something like this?
