The view presented in The Internet and Its Protocols is at once broad and deep. It covers all the common protocols and how they combine to create the Internet in its totality. More importantly, it describes each one completely, examining the requirements it addresses and the exact means by which it does its job. These descriptions include message flows, full message formats, and message exchanges for normal and error operation. They are supported by numerous diagrams and tables.This book's comparative approach gives you something more valuable: insight into the decisions you face as you build and maintain your network, network device, or network application. Author Adrian Farrel’s experience and advice will dramatically smooth your path as you work to offer improved performance and a wider range of services. * Provides comprehensive, in-depth, and comparative coverage of the Internet Protocol (both IPv4 and IPv6) and its many related technologies.* Written for developers, operators, and managers, and designed to be used as both an overview and a reference.* Discusses major concepts in traffic engineering, providing detailed looks at MPLS and GMPLS and how they control both IP and non-IP traffic.* Covers protocols for governing routing and transport, and for managing switches, components, and the network as a whole, along with higher-level application protocols.* Offers thoughtful guidance on choosing between protocols, selecting features within a protocol, and other service- and performance-related decisions.

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.

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.

An accessible, comic book-like, illustrated introduction to how the internet works under the hood, designed to give people a basic understanding of the technical aspects of the Internet that they need in order to advocate for digital rights. The internet has profoundly changed interpersonal communication, but most of us don't really understand how it works. What enables information to travel across the internet? Can we really be anonymous and private online? Who controls the internet, and why is that important? And... what's with all the cats? How the Internet Really Works answers these questions and more. Using clear language and whimsical illustrations, the authors translate highly technical topics into accessible, engaging prose that demystifies the world's most intricately linked computer network. Alongside a feline guide named Catnip, you'll learn about: • The "How-What-Why" of nodes, packets, and internet protocols • Cryptographic techniques to ensure the secrecy and integrity of your data • Censorship, ways to monitor it, and means for circumventing it • Cybernetics, algorithms, and how computers make decisions • Centralization of internet power, its impact on democracy, and how it hurts human rights • Internet governance, and ways to get involved This book is also a call to action, laying out a roadmap for using your newfound knowledge to influence the evolution of digitally inclusive, rights-respecting internet laws and policies. Whether you're a citizen concerned about staying safe online, a civil servant seeking to address censorship, an advocate addressing worldwide freedom of expression issues, or simply someone with a cat-like curiosity about network infrastructure, you will be delighted -- and enlightened -- by Catnip's felicitously fun guide to understanding how the internet really works!

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.
