TUIC

Delicately-TUICed 0-RTT proxy protocol

Warning: TUIC's dev branch is under heavy development. For end-user, please check out the latest released tag

Introduction

TUIC is a proxy protocol focusing on minimize the additional handshake latency caused by relaying as much as possible, as well as keeping the protocol itself being simple and easy to implement

TUIC is originally designed to be used on top of the QUIC protocol, but you can use it with any other protocol, e.g. TCP, in theory

When paired with QUIC, TUIC can achieve:

  • 0-RTT TCP proxying
  • 0-RTT UDP proxying with NAT type Full Cone
  • 0-RTT authentication
  • Two UDP proxying modes:
    • native: Having characteristics of native UDP mechanism
    • quic: Transferring UDP packets losslessly using QUIC streams
  • Fully multiplexed
  • All the advantages of QUIC, including but not limited to:
    • Bidirectional user-space congestion control
    • Optional 0-RTT connection handshake
    • Connection migration

Fully-detailed TUIC protocol specification can be found in SPEC.md
