Msquic
MsQuic es una implementación multiplataforma basada en C del protocolo QUIC. Proporciona una biblioteca de red para establecer enlaces de transporte cifrados y autenticados sobre UDP, integrando TLS para asegurar que todos los flujos de datos entre puntos finales estén cifrados.
La implementación utiliza una capa de enlace agnóstica al lenguaje para soportar lenguajes de alto nivel incluyendo C#, Rust y C++. Cuenta con migración basada en ID de conexión para mantener sesiones activas cuando cambian las direcciones IP o los puertos, y emplea multiplexación de múltiples flujos para gestionar flujos de datos independientes dentro de una única conexión.
La biblioteca cubre primitivas de transporte de red como intercambio de flujo bidireccional, escucha de conexiones y transmisión de datagramas no confiables. También incluye configuraciones para la seguridad de la conexión y emplea E/S asíncrona basada en eventos para optimizar el rendimiento de la red.
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.
