This book provides thorough knowledge of Linux TCP/IP stack and kernel framework for its network stack, including complete knowledge of design and implementation. Starting with simple client-server socket programs and progressing to complex design and implementation of TCP/IP protocol in linux, this book provides different aspects of socket programming and major TCP/IP related algorithms. In addition, the text features netfilter hook framework, a complete explanation of routing sub-system, IP QOS implementation, and Network Soft IRQ. This book further contains elements on TCP state machine implementation,TCP timer implementation on Linux, TCP memory management on Linux, and debugging TCP/IP stack using lcrash

As open source software becomes a trusted part of business and research systems, it's no wonder that a combination of the Transmission Control Protocol/Internet Protocol (TCP/IP) and the Linux operating system is becoming more common. TCP/IP's prevalence allows easy communication among computers using various operating systems, whether Windows, Mac OS, Linux, or Unix. And Linux—because it is open source and thus modifiable—has become a frequent choice for developers who want a customizable operating system on which to build their applications.

This book describes the design and implementation of TCP/IP in Linux, from simple client-server applications to more complex executions. Topical coverage includes:

* Basic socket concepts and implementations
* The Linux implementation of network packets
* TCP read/write
* TCP algorithms for data transmission and congestion control
* TCP timers
* IP layer and routing tables implementation
* IP forwarding and quality of service implementation
* Netfilter hooks for the stacks
* Network Soft IRQ
* How to debug a TCP/IP stack

All topics are discussed in a concise, step-by-step manner and the book is complemented with helpful illustrations to give readers a better understanding of the subject. TCP/IP Architecture, Design, and Implementation in Linux is an indispensable resource for embedded-network product developers, network security product developers, IT network architects, researchers, and graduate students
