Internet Core Protocols : The Definitive Guide

Rating:
Summary: good book but too much repeated stuff
Review: Very good presentation and description of core protocols (ip, icmp, igmp udp/tcp, arp) and at the right in-depth level I believe (if you want to get more in-depth, the rfc are there for that).
Anyway the book could be made much better just removing stuff since it contains way too much duplicated info. First there are whole paragraphs repeated exactly the same just a few pages away. I think this can get quite offensive (do you think I'm so dumb that I don't remember?).
And then there are the screenshots which are not very appropriate here since this is not an application review. A well formatted packet decode a'la tcpdump/snoop would be much better since screenshots display lots of useless stuff (menus, toolbars, etc) and for big packets a single screenshot can't fit the whole thing so you have to include two or more of them introducing discontinuities.
Furthermore screenshots are uselessly duplicated throughout the book. For example a simple ip header contains jsut 12 fields so a single screenshot can fit them all, anyway to describe these fields, the same screenshot is duplicated 14 times, from page 59 to page 77, and then a few more times. This happens for all the protocols and each screenshot takes about 66% of a page, so this is a real waste of paper! Often it gets really ridiculous when you have the same screenshot on 2 facing pages so you don't even have to slightly rotate your eyes to find them ;-)
