TUIC defines a standardized network proxy protocol for relaying TCP and UDP traffic.
- Proxying TCP and UDP traffic in 0-RTT.
- Achieving Full Cone NAT compatibility for UDP proxying.
- Supporting both lossy and lossless (via streams) UDP proxying.
- Leveraging the advantages of QUIC, including:
- Integrated secure transport and reliable data transfer.
- Bidirectional user-space congestion control.
- Stream multiplexing.
- Connection migration.
- Prioritizing simplicity, flexibility, and future extensibility.
There is no official implementation of the TUIC protocol in this repository. This is to focus on the protocol design itself and avoid duplicating efforts on features already well-established in other implementations.
TUIC is standardized as an implementation-agnostic protocol. The protocol specification is defined in SPEC.md.
For a specific protocol version, implementation changes are not expected. However, different protocol versions are not guaranteed to be compatible with each other.
The latest protocol version is 0x05.
Third-party implementations of the TUIC protocol are a fundamental part of the community and are highly appreciated and encouraged.
The implementations listed below are sorted alphabetically by name. Note that front-end applications based on other implementations are not listed here.
If your implementation is not listed, feel free to open a pull request to add it.
