Written by networking veteran with 20 years of experience, Network Warriorprovides a thorough and practical introduction to the entire networkinfrastructure, from cabling to the routers. What you need to learn topass a Cisco certification exam such as CCNA and what you need to knowto survive in the real world are two very different things. Thestrategies that this book offers weren ‘t on the exam, but they ‘reexactly what you need to do your job well.
Network Warrior takes you step by step through the world ofhubs, switches, firewalls, and more, including ways to troubleshoot acongested network, and when to upgrade and why. Along the way, you ‘llgain an historical perspective of various networking features, such asthe way Ethernet evolved. Based on the author ’s own experience as wellas those he worked for and with, Network Warrior is a Cisco-centricbook, focused primarily on the TCP/IP protocol and Ethernet networks —the realm that Cisco Systems now dominates. The book covers:

• 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

• Content switch module in action
• Designing QOS and what QOS does not do
