F-Stack/f-stack
F Stack
f-stack est un framework de contournement du noyau (kernel-bypass) et une stack TCP/IP en espace utilisateur conçue pour augmenter les vitesses de traitement des paquets et le débit global. Il utilise DPDK pour router le trafic réseau directement vers l'espace utilisateur et intègre une stack réseau FreeBSD transplantée pour gérer les protocoles de transport et de couche réseau en dehors du système d'exploitation hôte.
Le projet fournit une couche de compatibilité d'API socket qui permet aux applications réseau standard de s'exécuter sur un backend haute performance sans nécessiter de changements de code. Il propose également une API réseau basée sur des coroutines et une interface de micro-threading pour gérer les E/S réseau asynchrones et les tâches avec état sans l'utilisation d'une logique de callback complexe.
Le framework couvre l'implémentation TCP/IP à haut débit, la mise à l'échelle des connexions concurrentes et le multiplexage d'E/S piloté par les événements. Il inclut des capacités de configuration de routage pour déterminer si le trafic entrant est géré par la stack en espace utilisateur ou par la stack réseau standard du noyau.
