This project is a high-performance implementation of the QUIC transport protocol, providing a library for establishing multiplexed, low-latency network connections over UDP. It serves as a foundational networking stack for building modern web servers and clients, with native support for HTTP/3 and WebTransport standards.
The library distinguishes itself through advanced connection management, including the ability to maintain stable sessions across changing network paths or IP addresses using connection identifiers. It optimizes data throughput by employing packet batching to reduce kernel overhead and dynamic flow control windowing to prevent congestion. Furthermore, it supports zero-round-trip handshake resumption, allowing clients to transmit application data immediately upon reconnection by reusing cached cryptographic state.
Beyond core transport capabilities, the project provides a comprehensive suite of tools for traffic regulation, network observability, and proxying. It includes mechanisms for bidirectional and unidirectional stream management, unreliable datagram transmission, and graceful connection termination. The implementation also handles complex scenarios such as NAT rebinding recovery, path MTU discovery, and protocol version negotiation to ensure reliable communication in diverse network environments.
The library is written in Go and provides a modular API for configuring transport parameters, managing concurrent streams, and integrating with existing network clients.
