<h1 align="center"><img src="docs/images/readme_logo.png" width="500" alt="MsQuic logo"/></h1>

MsQuic is a Microsoft implementation of the IETF QUIC protocol. It is cross-platform, written in C and designed to be a general purpose QUIC library. MsQuic also has C++ API wrapper classes and exposes interop layers for both Rust and C#.

Protocol Features

QUIC has many benefits when compared to existing "TLS over TCP" scenarios:

• All packets are encrypted and handshake is authenticated with TLS 1.3.
• Parallel streams of (reliable and unreliable) application data.
• Exchange application data in the first round trip (0-RTT).
• Improved congestion control and loss recovery.
• Survives a change in the clients IP address or port.
• Stateless load balancing.
• Easily extendable for new features and extensions.

Library Features

MsQuic has several features that differentiates it from other QUIC implementations:

• Optimized for client and server.
• Optimized for maximal throughput and minimal latency.
• Asynchronous IO.
• Receive side scaling (RSS) support.
• UDP send and receive coalescing support.
