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#.

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.
  • Kernel stack bypass via XDP.
