This is the Linux/POSIX Sockets Version of Volume III from the most popular TCP/IP Internetworking series ever published. Volume III answers the question, "How does application software us TCP/IP to communicate over an Internet?" The Linux/POSIX Sockets Version is organized for easy reading. First the text explains the client-server paradigm and socket API that application programs use for network communication. It then discusses how the basic tools can be used to create servers, emphasizing practical designs and techniques that are important to programmers.

FEATURES

• Practical client-server design principles and techniques are presented with the strengths and weaknesses of each approach.
• The most complete coverage of server technology shows how to select among server algorithms and build an advanced server appropriate for each application.
• A wide range of server designs applicable to the WWW and other applications are discussed.
• Chapters on streaming technology and the Real-Time Transport Protocol explain how to transfer audio and video over the Internet.
• Each client-server design is illustrated with a detailed example implementation that has been tested under Linus; all code from the book is available on a Web site.
• The book examines powerful techniques such as application gateways and tunneling.
• It includes the clearest explanation of remote procedure call (RCP) and how it can be used to construct distributed programs.

Internetworking with TCP/IP, Volume III describes the fundamental concepts of client-server computing used to build all distributed computing systems, and presents an in-depth guide to the Posix sockets standard utilized by Linux and other operating systems. Dr. Douglas E. Comer compares leading server designs, and describes the key tools and techniques used to build clients and servers, including Remote Procedure Call (RPC). The book contains examples of running programs that illustrate each approach. Comer introduces the client-server model and its software design implications; the role of concurrent processing and threads; the Socket API, and differences that impact Linux programmers. Understand the key algorithms and issues associated with client and server software design; then review three leading approaches: iterative, connectionless servers (UPD); and both iterative and concurrent connection-oriented servers (TCP). The book contains extensive coverage of threading, including a new chapter on using threads for concurrency; as well as coverage of single-threaded and multi-threaded concurrent servers. Comer introduces multi-protocol and multi-service services; reviews client concurrency; tunneling at the transport and application levels; and external data representation (XDR). He reviews RPC, distributed program generation, NFS concepts and protocol; Telnet; streaming media transport; and finally, techniques for avoiding deadlock and starvation in client-server systems. For everyone who wants to master TCP/IP and understand how the Internet works.
