Msquic
MsQuic 是一个跨平台的、基于 C 语言的 QUIC 协议实现。它提供了一个网络库，用于在 UDP 之上建立加密和身份验证的传输链路，并集成 TLS 以确保端点之间的所有数据流均已加密。
该实现利用语言无关的绑定层来支持包括 C#、Rust 和 C++ 在内的高级语言。它具有基于连接 ID 的迁移功能，以在 IP 地址或端口更改时维持活动会话，并采用多流复用（multi-stream multiplexing）来管理单个连接内的独立数据流。
该库涵盖了网络传输基元，如双向流交换、连接监听和不可靠数据报传输。它还包括连接安全配置，并采用异步事件驱动的 IO 来优化网络吞吐量。
Features
- UDP Transport Implementations - Implements the QUIC protocol as a custom reliable transport layer over UDP for low-latency data delivery.
- C++ Networking Libraries - Acts as a low-level C networking toolkit with bindings for C++, C#, and Rust.
- QUIC Implementations - Implements the IETF QUIC transport protocol to provide encrypted, multiplexed links over UDP.
- Stream Multiplexing - Manages multiple independent data streams within a single connection to eliminate transport-level head-of-line blocking.
- Connection Migrators - Enables active network sessions to persist across changing IP addresses or ports using connection identifiers.
- C Network Protocol Implementations - Provides a high-performance implementation of the QUIC network protocol written in C for cross-platform portability.
- Cross-Platform C Libraries - Provides a portable C library for low-level networking that works consistently across multiple operating systems.
- TLS 1.3 Protocol Implementations - Integrates a TLS 1.3 implementation directly into the connection handshake to ensure mandatory encryption for all streams.
- Secure Connection Handlers - Implements secure connection handlers that manage TLS encryption and the QUIC handshake process.
- TLS Traffic Encryption - Integrates TLS parameters to ensure all data flows between endpoints are fully encrypted.
- Multiplexed Stream Exchanges - Enables sending and receiving application information through concurrent unidirectional or bidirectional streams.
- Data Throughput Optimizers - Provides network throughput optimization through asynchronous I/O and kernel stack bypass techniques.
- High-Throughput Network Engineering - Optimizes data transfer rates and minimizes latency through asynchronous I/O and kernel bypass techniques.
- Network Listeners - Provides the ability to listen for and accept incoming network requests on specific addresses and protocols.
- Connection Establishment - Handles the initiation and finalization of encrypted transport links during the QUIC handshake phase.
- Data Streaming - Supports the transmission of reliable and unreliable data across parallel streams using zero-round-trip handshakes.
- Unreliable Datagram Transports - Allows the transmission of secure data packets that do not require retransmission, provided the capability is negotiated.
- Multi-Language Binding Layers - Exposes a stable C API surface that allows integration with high-level languages including C#, Rust, and C++.
- Stream Encryption and Decryption - Provides secure, encrypted data streams using integrated TLS security and authenticated handshakes.
- Event-Driven I/O - Implements an asynchronous event-driven I/O model to handle high-concurrency network operations with minimal thread overhead.
