The TCP/IP "bible" now completely updated to reflect all the latest technologies! Leading Internet expert Douglas Comer has updated his classic, superb introduction to TCP/IP-based internetworking that is renowned for its clarity and accessibility in explaining internetworking and routing. Discover how the basic TCP/IP technology has survived and evolved over two decades of exponential growth, and understand the TCP/IP protocols and technical advances. This edition explains emerging technologies such as Mobile IP, Virtual Private Networks, resource reservation with RSVP, and Ipv6. Comer reveals how to master TCP/IP and how the Internet works. The reader is required to have a modest background in the fundamentals of computer systems, but does not need sophisticated mathematics. As with previous editions, this edition provides an introduction to physical networks and then shows how they are combined to form an internet. It states design principles clearly, and discusses motivations and consequences. THIS NEW EDITION OF VOLUME 1: Explains how voice and video are sent over IP internets and how IP Telephony operates Describes Mobile IP (a technology that allows a computer to move from one network to another without changing its IP address) Discusses IP security and the security standard, IPsec Revises the discussion of Ipv6 to incorporate the latest changes Shows how to interconnect private intranets and the global Internet using Virtual Private Network (VPN) and Network Address Translation (NAT) technologies Expands the description of IP multicasting to cover multicast routing protocols Presents the Differentiated Services (DiffServe) scheme for classes of services as well at Path MTU discovery and routing for anonymous serial networks Explains Random Early Discard (RED), which is now recommended for routers Updates the coverage of all protocols to the latest versions, including RIP, IGMP, and SNMPComer, Douglas E. is the author of 'Internetworking With Tcp/Ip Principles, Protocols, and Architecture', published 2000 under ISBN 9780130183804 and ISBN 0130183806.
