DPDK/dpdk
Dpdk
DPDK es un framework de procesamiento de paquetes y librería de red de bypass de kernel diseñada para acelerar el rendimiento del plano de datos de red. Proporciona una pila de red en espacio de usuario que mueve los datos de red directamente desde la tarjeta de interfaz de red al espacio de usuario, eliminando la sobrecarga del kernel del sistema operativo para lograr un alto rendimiento y baja latencia.
El framework utiliza una arquitectura de controlador de modo de sondeo (poll mode driver) que reemplaza la red impulsada por interrupciones con un mecanismo de sondeo constante. Este enfoque permite la implementación de funciones y protocolos de red fuera del kernel.
El proyecto cubre capacidades para el procesamiento de paquetes de alto rendimiento, virtualización de funciones de red y el desarrollo de dispositivos de red personalizados como firewalls y balanceadores de carga.
Features
- Packet Processing Frameworks - Provides a high-performance framework for accelerating packet processing by moving network data directly from the NIC to user space.
- Poll-Mode Drivers - Employs a poll-mode driver architecture that continuously checks hardware for packets to eliminate interrupt latency.
- Network Stack Bypasses - Implements a networking library that bypasses the standard kernel network stack to achieve high throughput.
- User-Space Network Interface Access - Moves network driver logic from the kernel to user space to achieve faster data transfer.
- High-Performance Packet Processing - Handles massive volumes of network traffic by bypassing the OS kernel to reduce latency and CPU overhead.
- User-Space Packet Processing - Provides high-speed network packet manipulation by bypassing standard kernel overhead.
- Direct I/O Access - Provides direct I/O access to move network traffic from hardware to user-space memory, bypassing the kernel.
- User-Space Implementations - Provides tools for implementing network protocols in user space to maximize throughput and avoid kernel context switches.
- Zero-Copy Buffers - Implements zero-copy buffer management by passing pointers to packet data across processing stages.
- Single-Producer Single-Consumer Queues - Implements single-producer single-consumer lockless ring buffers for high-speed data exchange between CPU cores.
- Network Appliance Frameworks - Provides a framework for building specialized network appliances such as firewalls and load balancers.
- Hugepage Allocations - Implements hugepage-based memory allocation to improve memory access speed and reduce TLB misses for packet buffers.
- Virtualization Networking - Enables the creation of virtualized network services that process packets at near-wire speed.
- Run-To-Completion Models - Uses a run-to-completion model by assigning a packet to a single CPU core for all processing steps.
- Librerías de redes - Libraries and drivers for fast packet processing.
