Product Description

If you’ve ever wondered how Linux carries out the complicated tasks assigned to it by the IP protocols — or if you just want to learn about modern networking through real-life examples — Understanding Linux Network Internals is for you.Like the popular O’Reilly book, Understanding the Linux Kernel, this book clearly explains the underlying concepts and teaches you how to follow the actual C code that implements it. Although some background in the TCP/IP protocols is helpful, you can learn a great deal from this text about the protocols themselves and their uses. And if you already have a base knowledge of C, you can use the book’s code walkthroughs to figure out exactly what this sophisticated part of the Linux kernel is doing.Part of the difficulty in understanding networks — and implementing them — is that the tasks are broken up and performed at many different times by different pieces of code. One of the strengths of this book is to integrate the pieces and reveal the relationships between far-flung functions and data structures. Understanding Linux Network Internals is both a big-picture discussion and a no-nonsense guide to the details of Linux networking. Topics include:Key problems with networkingNetwork interface card (NIC) device driversSystem initializationLayer 2 (link-layer) tasks and implementationLayer 3 (IPv4) tasks and implementationNeighbor infrastructure and protocols (ARP)BridgingRoutingICMPAuthor Christian Benvenuti, an operating system designer specializing in networking, explains much more than how Linux code works. He shows the purposes of major networking features and the trade-offs involved in choosing one solution over another. A large number of flowcharts and other diagrams enhance the book’s understandability.

It provides an unique voyage within the Kernel’s networkinkg code., November 21, 2009
By Rafael Azenha Aquini
As far as I know, there is not another book like this. It complements very well the Kernel book written by Bovet & Cesati, and goes beyond giving to the reader a complete scenario about the Linux Network Internals. Extremely rich in technical details, this book certainly will provide you an unique overview about the subject.

Outstanding coverage of the core networking code, August 12, 2009
By Mook Merkin
An unbelievable job covering the core networking code. If the author of this book had a follow-on volume including things left out due to space constraints, I would buy it in a heart-beat. This things easily saves months of time reading code (though face it, that’s necessary too).

Excellent Book For Those Who want to know How Linux Network Stack Works, April 7, 2009
By Venkatram Tummala
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.!

Very nice and cheap item, February 14, 2009
By J. Chiang
the item is just as the description of the seller, and it’s a good transaction

Excellent, in depth review of Linux Networking, January 7, 2009
By Nicholas A. Barendt
The book was exactly what I was looking for – a practical, in-depth explanation and review of the various software components that make up the Linux kernel’s network stack.
