Diving into the Linux Networking Stack, Part I | Beyond Syntax | Michael J. Schultz
This is the first part of a (planned) multi-part series on receiving a network packet on a modern Linux kernel. Have you ever wondered what happens when your Linux machine gets a packet from the network? I have, but most of the information I've seen is concerned with the 2.4.x kernel. For my own sake, I decided to take a walk through the Linux networking stack (using Linux kernel 2.6.37) and thoug

X86 hardware for packet processing
This document discusses hardware and software requirements for high-performance packet processing. It covers Direct Cache Access (DCA) which allows network cards to directly write received packets to the CPU cache to reduce memory traffic. It also discusses virtualization techniques like Virtual Machine Device Queues (VMDq) and Receive-Side Scaling (RSS) which improve performance by distributing n
