A one-of-a-kind description about using the Linux operating system on a TCP/IP network Boasting high-performance, high availability, and open source code, Linux has emerged as an optimal choice for an operating system. Yet for Linux to be adopted by the mainstream of Unix-based corporate and ISP networks, it must be capable of supporting the TCP/IP Internet protocol, like any other network operating system. This book provides the rapidly growing audience of Linux site managers, as well as researchers and developers worldwide, with the information they need on how Linux TCP/IP keeps the network running. Internationally recognized expert on Internetworking, Jon Crowcroft walks readers through the Linux TCP/IP protocol stack, offering detailed explanations on how Linux implements its communications protocols. Vinton Cerf--co-inventor of TCP/IP--is the technical editor for this book.
JON CROWCROFT is Marconi Professor of Communications Systems at the University of Cambridge. He is a member of the Internet Architecture Board (IAB) of IETF, which provides oversight for Internet standards. He is also a senior member of IEEE and a Fellow of the Royal Academy of Engineering. IAIN PHILLIPS is a lecturer in the Department of Computer Science at Loughborough University, where he was previously a Research Fellow in the Department of Electronic and Electrical Engineering. He is a member of the British Computer Society and a Chartered Engineer.
