Written by networking veteran with 20 years of experience, Network Warrior provides a thorough and practical introduction to the entire network infrastructure, from cabling to the routers. What you need to learn to pass a Cisco certification exam such as CCNA and what you need to know to survive in the real world are two very different things. The strategies that this book offers weren 't on the exam, but they 're exactly what you need to do your job well. Network Warrior takes you step by step through the world of hubs, switches, firewalls, and more, including ways to troubleshoot a congested network, and when to upgrade and why. Along the way, you 'll gain an historical perspective of various networking features, such as the way Ethernet evolved. Based on the author 's own experience as well as those he worked for and with, Network Warrior is a Cisco-centric book, focused primarily on the TCP/IP protocol and Ethernet networks -- the realm that Cisco Systems now dominates. The book covers: The type of networks now in use, from LANs, WANs and MANs to CANs

• The OSI Model and the layers involved in sending data

• Hubs, repeaters, switches, and trunks in practice

• Auto negotiation and why it 's a common problem in network slowdowns

• Route maps, routing protocols, and switching algorithms in Cisco routers

• The resilient Ethernet -- how to make things truly redundant

• Cisco 6500 multi-layer switches and the Catalyst 3750 switch

• Telecom nomenclature -- why it 's different from the data world

• T1 and DS3

• Firewall theory, designing access lists, authentication in Cisco devices

• Server load balancing technology

• Content switch module in action

• Designing QOS and what QOS does not do

• IP design and subnetting made easy

The book also explains how to sell your ideas to management, how networks become a mess as a company grows, and why change control is your friend. Network Warrior will help network administrators and engineers win the complex battles they face every day.

A good book, but weak on routing. - 2009-04-03
Reviewer Rating:
I like this book, but I found it was weak on the contents of routing, it seems that the author's knowledge limited for routing, the reader will be easily confused for this part. I recommend "routing tcp/ip" for routing.

Does what it claims to do - 2009-10-03

Total gap filler. Take theory learned in CCNA add real life and you have this book. If you work with Cisco gear and need a go-to refresher this is it. Great on the job every day book for network admins and engineers, also recommend for anyone who is thinking about CCNP. My new favorite networking book.

Good Book - 2009-04-21
Reviewer Rating:
This epically-titled O'Reilly book is a well-organized collection of network configuration tips, stories, and common "gotchas", as told by a self-admitted grouchy old network admin to younger, wet-behind-the-ears network administrators.

The author, in a move uncommon to most networking manuals, just cuts to the chase and says what needs to be said. Everything is told from a Cisco perspective, with Cisco terminology, and the only hint of variation allowed for is the occasional explanation when something is radically (or subtly, in some way that would ruin everything when you least expect it) different between CatOS and IOS. This is undeniably a good thing; it keeps the book short, and realistically, Cisco is one
of the forefront leaders in the enterprise network market.

A wide range of topics are talked about - possible problems that you could run into with auto-negotiation on your fast-ethernet network, how to configure spanning tree or etherchannel, getting QoS to work properly, and a whole host of topics one should know when creating one's own medium-to-large sized network. Even for those that already know how to implement these features, the author explains exactly when someone would want to use these features and how they evolved, and how they ought to be properly used.

I would recommend this book to anyone interested in enterprise
networking - ranging from the relatively professionally uninitiated like myself (I only do networking administration for Computer Science House at the Rochester Institute of Technology) to those who are just transitioning from networking classes to actual jobs, who will benefit perhaps the most from the book's tips and tricks from a person in industry, or even the average middle-aged network administrator, who may find a large portion of the book a snooze, but likely still pick up a trick or two that was previously unknown.

It's amazing book. - 2009-06-25
Reviewer Rating:
More advanced than others, so it's indicate to experienced professionals. If you like to discover special things about network, it's the goal.

Excellent Read - 2009-06-15

This is the best book I've read this year (2009). It explains core principles of networking in such a way that everyone understands. I feel much more knowledgeable and confident in my networking ability now after reading this book.
