| 83 | +<p>MsQuic is a Microsoft implementation of the <a href="https://datatracker.ietf.org/wg/quic/about/">IETF QUIC</a> |
| 84 | +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 <a href="https://docs.rs/msquic/latest/msquic/">Rust</a> and C#.</p> |

| 105 | +<p>QUIC has many benefits when compared to existing "TLS over TCP" scenarios:</p> |
| 106 | +<ul> |
| 107 | +<li>All packets are encrypted and handshake is authenticated with TLS 1.3.</li> |
| 108 | +<li>Parallel streams of (reliable and unreliable) application data.</li> |
| 109 | +<li>Exchange application data in the first round trip (0-RTT).</li> |
| 110 | +<li>Improved congestion control and loss recovery.</li> |
| 111 | +<li>Survives a change in the clients IP address or port.</li> |
| 112 | +<li>Stateless load balancing.</li> |
| 113 | +<li>Easily extendable for new features and extensions.</li> |
| 114 | +</ul> |
| 115 | +<h2 id="library-features">Library Features</h2> |
| 116 | +<p>MsQuic has several features that differentiates it from other QUIC implementations:</p> |
| 117 | +<ul> |
| 118 | +<li>Optimized for client and server.</li> |
| 119 | +<li>Optimized for maximal throughput and minimal latency.</li> |
| 120 | +<li>Asynchronous IO.</li> |
| 121 | +<li>Receive side scaling (<a href="https://docs.microsoft.com/en-us/windows-hardware/drivers/network/introduction-to-receive-side-scaling">RSS</a>) support.</li> |
| 122 | +<li>UDP send and receive coalescing support.</li> |
| 123 | +<li>Kernel stack bypass via <a href="https://github.com/microsoft/xdp-for-windows?tab=readme-ov-file#xdp-for-windows">XDP</a>.</li> |
