Delicately-TUICed 0-RTT proxy protocol
Warning: TUIC's dev branch is under heavy development. For end-user, please check out the latest released branch
TUIC is a proxy protocol focusing on the simplicity. It aims to minimize the additional handshake latency caused by relaying as much as possible
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 mechanismquic: Transferring UDP packets losslessly using QUIC streams
- Fully multiplexed
- All the advantages of QUIC:
- Bidirectional user-space congestion control
- Connection migration
- Optional 0-RTT connection handshake
There are 4 crates provided in this repository:
- tuic - Library. The protocol itself, protocol & model abstraction, synchronous / asynchronous marshalling
- tuic-quinn - Library. A thin layer on top of quinn to provide functions for TUIC
- tuic-server - Binary. Minimalistic TUIC server implementation as a reference, focusing on the simplicity
- tuic-client - Binary. Minimalistic TUIC client implementation as a reference, focusing on the simplicity
