This Second Edition of Volume III is from the most popular TCP/IP Internetworking series ever published. Software design is used as the central theme to answer, "How does application software use TCP/IP?" The text concentrates on how to use an Internet. The client-server paradigm is presented by using standard protocols to illustrate algorithms, designs, and implementation techniques such as gateway and tunneling. The authors have incorporated the latest standards by rewriting the extensive code in ANSI C and discussing changes in protocols. New sections explain concepts such as slirp, the application gateway program that provides Internet access across a dial-up connection. Meant for all the computer science students and professionals alike, the text offers the most complete coverage of: * Advanced server technology and its applications. * Remote procedure call (RPC) and its use in constructing distributed programs. * Concurrent processing as it applies to all concurrent programs and network applications. * All software, including the new code in ANSI C, available by FTP. * Comprehensive coverage of deadlock and livelock.
