Introduction to Network Analysis, 2nd Edition

The ultimate introductory guide to analyzing network communications at the packet level. This book defines basic analyzer elements (such as capture filters, display filters, expert alarms, trend screens, and decode windows) and provides real-world examples of how an analyzer can be used to troubleshoot networks. Includes chapter tests and several trace files for practice.

Packet Guide to Routing and Switching

Go beyond layer 2 broadcast domains with this in-depth tour of advanced link and internetwork layer protocols, and learn how they enable you to expand to larger topologies. An ideal follow-up to Packet Guide to Core Network Protocols, this concise guide dissects several of these protocols to explain their structure and operation.This isn't a book on packet theory. Author Bruce Hartpence built topologies in a lab as he wrote this guide, and each chapter includes several packet captures. You'll learn about protocol classification, static vs. dynamic topologies, and reasons for installing a particular route.This guide covers:Host routing, Process a routing table and learn how traffic starts out across a network Static routing, Build router routing tables and understand how forwarding decisions are made and processed Spanning Tree Protocol. Learn how this protocol is an integral part of every network containing switches Virtual Local Area Networks. Use VLANs to address the limitations of layer 2 networks Trunking. Get an indepth look at VLAN tagging and the 802.1Q protocol Routing Information Protocol. Understand how this distance vector protocol works in small, modern communication networks Open Shortest Path First, Discover why convergence times of OSPF and other link state protocols are improved over distance vectors.

Packet Guide to Core Network Protocols

Take an in-depth tour of core Internet protocols and learn how they work together to move data packets from one network to another. With this concise book, you'll delve into the aspects of each protocol, including operation basics and security risks, and learn the function of network hardware such as switches and routers.Ideal for beginning network engineers, each chapter in this book includes a set of review questions, as well as practical, hands-on lab exercises.Understand basic network architecture, and how protocols and functions fit together Learn the structure and operation of the Ethernet protocol Examine TCP/IP, including the protocol fields, operations, and addressing used for networks Explore the address resolution process in a typical IPv4 network Become familiar with switches, access points, routers, and other network components that process packets Discover how the Internet Control Message Protocol (ICMP) provides error messages during network operations Learn about the network mask (subnetting) and how it helps determine the network.
