Understanding Linux Network Internals Review by Venkatram Tummala

Excellent Book For Those Who want to know How Linux Network Stack Works

If you already have knowledge about how computer networks work in general & want to know how those networking concepts are actually designed & implemented in an operating system, this book is a must. This Book is a smooth read & goes step by step.

First it tells you how a NIC registers itself with the kernel. Then it describes an high-level introduction of how device drivers drive the device. Then it describes the interface between the kernel and the device drivers. It also discusses bridging & routing concepts.

If you want to delve into the linux networking code of the kernel or if you are actually looking to modify a part of the networking code, this book is a must read.

This book doesn't cover the transport layer though.! You have to refer to other sources to knit all the pieces of the puzzle together.!
