NEXT Understanding Linux Network Internals By Christian Benvenuti Publisher O Reilly Pub Date December 2005 ISBN 0-596-00255-6 Pages 1062 Table of Contents Index Overview 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 networking Network interface card NIC device drivers System initialization Layer 2 link-layer tasks and implementation Layer 3 IPv4 tasks and implementation Neighbor infrastructure and protocols ARP Bridging Routing ICMP Author 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 .
