MsQuic

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.

Protocol Features

RFC: 9000, 9001, 9002 Draft: Datagram, Version Negotiation, Load Balancing, ACK Frequency, Perf Testing

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.
