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.
Important The QUIC protocol is currently in IETF last call (not RFC quite yet). MsQuic implements the latest published drafts.
IETF Drafts: Transport, TLS, Recovery, Datagram, Load Balancing
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.

Important - We are still bringing up important regression tests for the core code. Until they are onboarded, any external contributions to the core or kernel mode files in the platform will not be accepted. This is only a temporary restriction and we are working to complete it by the end of 2020.
