Hands-on networking experience, without the lab! The best way to learn about network protocols is to see them in action. But that doesn't mean that you need a lab full of networking equipment. This revolutionary text and its accompanying CD give readers realistic hands-on experience working with network protocols, without requiring all the routers, switches, hubs, and PCs of an actual network. Computer Networking: Internet Protocols in Action provides packet traces of real network activity on CD. Readers open the trace files using Ethereal, an open source network protocol analyzer, and follow the text to perform the exercises, gaining a thorough understanding of the material by seeing it in action. Features * Practicality: Readers are able to learn by doing, without having to use actual networks. Instructors can add an active learning component to their course without the overhead of collecting the materials. * Flexibility: This approach has been used successfully with students at the graduate and undergraduate levels. Appropriate for courses regardless of whether the instructor uses a bottom-up or a top-down approach. * Completeness: The exercises take the reader from the basics of examining quiet and busy networks through application, transport, network, and link layers to the crucial issues of network security.

Today, the internet and computer networking are essential parts of business, learning, and personal communications and entertainment. Virtually all messages or transactions sent over the internet are carried using internet infrastructure- based on advanced internet protocols. Advanced internet protocols ensure that both public and private networks operate with maximum performance, security, and flexibility. This book is intended to provide a comprehensive technical overview and survey of advanced internet protocols, first providing a solid introduction and going on to discuss internetworking technologies, architectures and protocols. The book also shows application of the concepts in next generation networks and discusses protection and restoration, as well as various tunnelling protocols and applications. The book ends with a thorough discussion of emerging topics.

If you've ever been responsible for a network, you know that sinkingfeeling: your pager has gone off at 2 a.m., the network is broken, and you can't figure out why by using a dial-in connection from home. You drive into the office, dig out your protocol analyzer, and spend the next four hours trying to put things back together before the staff shows up for work. When this happens, you often find yourself looking at the low-level guts of the Internet protocols: you're deciphering individual packets, trying to figure out what is (or isn't) happening. Until now, the only real guide to the protocols has been the Internet RFCs--and they're hardly what you want to be reading late at night when your network is down. There hasn't been a good book on the fundamentals of IP networking aimed at network administrators--until now. Internet Core Protocols: The Definitive Guide contains all the information you need for low-level network debugging. It provides thorough coverage of the fundamental protocols in the TCP/IP suite: IP, TCP, UDP, ICMP, ARP (in its many variations), and IGMP. (The companion volume, Internet Application Protocols: The Definitive Guide, provides detailed information about the commonly used application protocols, including HTTP, FTP, DNS, POP3, and many others). It includes many packet captures, showing you what to look for and how to interpret all the fields. It has been brought up to date with the latest developments in real-world IP networking. The CD-ROM included with the book contains Shomiti's "Surveyor Lite," a packet analyzer that runs on Win32 systems, plus the original RFCs, should you need them for reference. Together, this package includes everything you need to troubleshoot your network--except coffee.

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 updated edition, you’ll dive into the aspects of each protocol, including operation basics and security risks, and learn the function of network hardware such as switches and routers. New chapters examine the transmission control protocol (TCP) and user datagram protocol in detail. Ideal for beginning network engineers, each chapter in this book includes a set of review questions, as well as practical, hands-on lab exercises. You’ll explore topics including: Basic network architecture: how protocols and functions fit together The structure and operation of the Ethernet protocol TCP/IP protocol fields, operations, and addressing used for networks The address resolution process in a typical IPv4 network Switches, access points, routers, and components that process packets TCP details, including packet content and client-server packet flow How the Internet Control Message Protocol provides error messages during network operations How network mask (subnetting) helps determine the network The operation, structure, and common uses of the user datagram protocol

Das Buch erklärt die grundlegenden Prinzipien paketvermittelter Netzwerke und den Schichtenaufbau der Protokolle. Sie finden hier Erläuterungen zu den vielen Begriffen und Akronymen, denen Sie auf dem Gebiet der modernen IP-Netzwerke begegnen. - behandelt einen Großteil der Probleme, mit denen Netzwerkdesigner und -betreiber konfrontiert werden: Netzwerkarchitektur und -topologie, Netzwerkzugriff, Protokollwahl, Routingprinzipien, Redundanz, Sicherheit, Firewalls, verteilte Anwendungen, Netzwerkdienste, Quality of Service usw. - ist so konzipiert, dass der Leser einzelne Themen unabhängig von den anderen erarbeiten kann - enthält ausführliche Anhänge (einschließlich Glossar) zu Protokollfeldnamen und -formaten sowie zu RFCs (Internetspezifikationen), die sich hervorragend als Nachschlagewerk für den Alltag verwenden lassen

Building on the strength of his two other successful texts, Stallings' new text provides a fresh "Top Down" and comprehensive "Top Down" survey of the entire field of computer networks and Internet technology-including an up-to-date report of leading-edge technologies. It emphasizes both the fundamental principles as well as the critical role of performance in driving protocol and network design. The basic themes of principles, design approaches, and standards throughout the text unify the discussion.

Attacking Network Protocols is a deep dive into network protocol security from James ­Forshaw, one of the world’s leading bug ­hunters. This comprehensive guide looks at networking from an attacker’s perspective to help you discover, exploit, and ultimately ­protect vulnerabilities. You’ll start with a rundown of networking basics and protocol traffic capture before moving on to static and dynamic protocol analysis, common protocol structures, cryptography, and protocol security. Then you’ll turn your focus to finding and exploiting vulnerabilities, with an overview of common bug classes, fuzzing, debugging, and exhaustion attacks. Learn how to: - Capture, manipulate, and replay packets - Develop tools to dissect traffic and reverse engineer code to understand the inner workings of a network protocol - Discover and exploit vulnerabilities such as memory corruptions, authentication bypasses, and denials of service - Use capture and analysis tools like ­Wireshark and develop your own custom network proxies to manipulate ­network traffic Attacking Network Protocols is a must-have for any penetration tester, bug hunter, or developer looking to understand and discover network vulnerabilities.
