1. Introduction

Hysteria2 is a feature-rich network tool optimized for poor network conditions (bilateral acceleration), such as satellite networks, congested public Wi-Fi, connecting to foreign servers from China, etc. It is based on a modified QUIC protocol.

It effectively addresses the biggest pain point when setting up proxy servers—poor network routes.
