Written to give students and professionals the basics required to implement network functionality in the Linux kernel, this book also addresses everyone who wants to deepen their understanding of network specific processes in an operating system. This book introduces the key components and mechanisms of the Linux kernel and the designs of communication systems.

The Linux Networking Architecture is a detailed description of the network subsystem in the newer versions of the Linux kernel. It explains how protocols work and establishes important concepts of the Linux network architecture from device drivers to application interfaces. In addition to central issues such as PPP, IP, firewalls, routing, TCP, NAT, UDP, and sockets, the book discusses more recent protocols and extensions such as PPPoE used in DSL access technologies, the Bluetooth^® driver, and quality-of-service support.

Features

All core protocols of the TCP/IP protocol family are covered, with additional treatment of supplementary protocols such as RSVP, Mobile IP and IP Security.

Each chapter contains:

• A conceptual introduction to the corresponding protocol
• Discussion of how the protocol's functionality is configured and administered
• Explanation of data structures, algorithms, and programming interfaces

Interface design is explained with a view to which design principles to use when protocols should be implemented.

The informational appendix further facilitates working with Linux, for instance, debugging in the Linux kernel.
