The Illustrated Network

How TCP/IP Works in a Modern Network


  • Walter Goralski, Juniper Networks, USA

In 1994, W. Richard Stevens and Addison-Wesley published a networking classic: TCP/IP Illustrated. The model for that book was a brilliant, unfettered approach to networking concepts that has proven itself over time to be popular with readers of beginning to intermediate networking knowledge. The Illustrated Network takes this time-honored approach and modernizes it by creating not only a much larger and more complicated network, but also by incorporating all the networking advancements that have taken place since the mid-1990s, which are many. This book takes the popular Stevens approach and modernizes it, employing 2008 equipment, operating systems, and router vendors. It presents an ?illustrated? explanation of how TCP/IP works with consistent examples from a real, working network configuration that includes servers, routers, and workstations. Diagnostic traces allow the reader to follow the discussion with unprecedented clarity and precision. True to the title of the book, there are 330+ diagrams and screen shots, as well as topology diagrams and a unique repeating chapter opening diagram. Illustrations are also used as end-of-chapter questions. A complete and modern network was assembled to write this book, with all the material coming from real objects connected and running on the network, not assumptions. Presents a real world networking scenario the way the reader sees them in a device-agnostic world. Doesn't preach one platform or the other.Here are ten key differences between the two:Stevens Goralski's Older operating systems (AIX,svr4,etc.) Newer OSs (XP, Linux, FreeBSD, etc.)Two routers (Cisco, Telebit (obsolete)) Two routers (M-series, J-series)Slow Ethernet and SLIP link Fast Ethernet, Gigabit Ethernet, and SONET/SDH links (modern)Tcpdump for traces Newer, better utility to capture traces (Ethereal, now has a new name!)No IPSec IPSecNo multicast MulticastNo router security discussed Firewall routers detailedNo Web Full Web browser HTML considerationNo IPv6 IPv6 overviewFew configuration details More configuration details (ie, SSH, SSL, MPLS, ATM/FR consideration, wireless LANS, OSPF and BGP routing protocols

"This book provides a diverse and solid foundation that will be immensely beneficial to new network engineers, those looking for a refresher or developers" -- Alan Young, Google, Network Surveillance Team "i haven't had time to read the manuscript completely. however, what i like about the book is it covers all the topics from basics to voip to mpls vpn to ssl and this is one of the key factor that separates this book. unlike other tcp/ip books which talk mostly about history this one talks about what is happening today. another great thing i like is the use of diagram and tools." -- Amit KT, Network Engineer, Peak Web Consulting, SF, CA "It looks like a very good primer for someone who is about to get serious about working in the networking field. The book describes several things that we take for granted like standards organizations. But if you are new to the industry it is good to be educated about how we arrive at standards." -- Landon Scott, Channel SE, Juniper Networks
