Even complex material, such as the ins and outs of dynamic routing protocols, described extensively and well documented. This is not a book holding hands, but also does not address the highly advanced aspects of the TCP / IP. Not only is Heather Osterloh explains how TCP / IP to work in his own words, he backs it all with reference to the appropriate standards documents so readers know where to look for more detail and an alternative explanation. Consider this book if you are prepping for the exam Cisco Certified Network Associate (CCNA) (640-507) or the Microsoft TCP / IP exam (70-059). In addition to the two protocols eponymous, this book covers routing protocols (RIP, OSPF, IGRP, EIGRP, and BGP), find the address protocol (ARP, RARP, and DHCP), and higher protocols (HTTP, SMTP, FTP, etc. other).
