Now you can keep up-to-date on all the major protocols of a TCP/IP-based network — without searching through dozens of detailed RFCs. All you need is this comprehensive, technical update, which describes the most interfaces of any single source and features an introduction to binary and hexadecimal arithmetic. This handy reference guide also provides exclusive coverage of L2TP, the hot new protocol being implemented by most manufacturers of routers and network access servers. Plus, it's the first to include LAN analysis screens and engineering-level detail on IPv6 routing. You will learn the fundamentals of the Internet and TCP/IP protocol suite and how it works — not with formal specifications but through the use of graphic illustrations and functional descriptions that are easy to understand. And to keep you up-to-date, the book includes detailed coverage of interface enhancements and revisions, as well as important new additions. Specifically, you will find: • An enhanced description of IP, including IPv6 — plus examples of dynamic routing such as RIPv2, OSPF, BGP, NAT, and CIDR • Enhanced descriptions of ARP, RARP, and BOOTP, with added descriptions of IARP, DHCP, and RADIUS • A revised description of FTP and an added description of HTTP This latest edition is a valuable one-source reference for a broad range of technical professionals, including data communications analysts, software engineers, hardware engineers, and software programmers. It is particularly well suited for those who need to know how all the major TCP/IP protocols work but don't require the fine details of formal specifications.
