# QUIC Transport

See also network

## Overview

QUIC is a new low-latency encrypted transport protocol, built on top of UDP.

## Packaging

The xpra.org RPM repositories include the dependencies required for running QUIC servers and clients for most distributions, namely `aioquic` and its dependencies.

Some distributions (ie: RHEL 8 / 9) may lack some of the dependencies, in which case you may need to install them using pip:

    pip3.XX install certifi pyOpenSSL cryptography

(be aware that these packages will not receive security updates from your package manager)

## SSL Options

SSL encryption is built into the QUIC protocol, so you need to provide the same configuration options as SSL.

## Notes

- QUIC is UDP based, you need to open the UDP port of your choosing on your firewall.
- some tuning may be needed
- xpra version 5.0 or later is required
