Packet Guide to Core Network Protocols
Publisher: O'Reilly Media
Final Release Date: June 2011
Pages: 264

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

    Comments about O'Reilly Media Packet Guide to Core Network Protocols:

    While the Internet is hit every six months by new technologies that remodel the way we think about it, the network protocols at its very core, those that make the magic possible, are still the same since decades. And they are likely to stay. Volumes have been written about computer networks and volumes will be written. In this jungle of texts, we find Packet Guide to Core Network Protocols, a title that, instead of covering the whole ISO/OSI model from A to Z, just focuses on the most important network protocols and concepts.

    Well, we all do forget things and, sometimes, get lost in the weeds: headers, hand-shakes, layers, ..help! It is true, while if you look at networking from a comfortable high perspective, everything is plain simple, once you get down to the wires and bits, things can become quite complex.

    Technically speaking, Bruce's text is easy to praise: it is very exhaustive and it provides the reader with all the details and secrets he could ever ask for about TCP/IP, ARP, Ethernet, and ICMP. Many meticulously detailed images and schemes devotedly follow the concepts being reviewed, making it easier to follow and get the picture. Each chapter comes with a summary and review Q&A, little things that add value over value.

    But while the book is technically impeccable, it targets a very small niche of professionals, those that already have a solid knowledge of computer networks and just need a quick refresh. Mere mortals, instead, will get overwhelmed by the huge quantity of information given: on the one hand, those that are just interested in a quick broad overview of networking will find way too much complexity to digest. On the other hand, students, those poor things that have to learn the fields of each header, will probably need a text that covers more than Core Network Protocols does, such as Computer Networks.

    So, tying it all together, a good book that targets a very selected groups of people. I don't feel like suggesting this book, despite its quality: either go for something that covers it all or get something easier.

    Comments about O'Reilly Media Packet Guide to Core Network Protocols:

    Before I start my review of this book, let me narrate a story. Recently I had a crisis at work where certain users were not able to invoke web services. Of course, we had well-tested software using agile methodology and all that. My team knew our front-end and our backend very well. What we weren't well-versed with was the connection by which our front-end communicated with the backend. We were in a war room with the networking experts for 2 days and I couldn't understand jack of what they were talking. I was clearly an "outsider" in their elite circle. Hence, I got interested in this book.

    This book is divided into seven chapters starting with networking models (OSI, TCP/IP) and ending with subnetting. Most of the material is dry but the author keeps the flow going steadily by providing screen printouts of Wireshark and explaining it with his pedantic style. Questions, answers, and exercises at the end of each chapter reinforce your learning. I liked chapter 5 (Network equipment) and Chapter 7 (Subnetting) very much as it is explained well and also I can relate it to my work.

    This book is certainly not for the faint of heart. It is not your grand-father's "Hello World" book. In fact, it reads like a computer science text book. The author has pain-stakingly tried to simplify it as much as he could. As Einstein said, "Keep it simple but not any simpler". A background in networking would help refresh your knowledge and this book serves exactly that. If you are an absolute beginner looking for a basic book on networking, this book is not for you. However, if it's been a few years since your last networking class, you should be able to pick things up with the help of this book.

      Comments about O'Reilly Media Packet Guide to Core Network Protocols:

      This book instructs a basic network architecture, and shows what is OSI Model? what is protocol? what is TCP/IP? It shows the sample (photo) from Wireshark tool, that help readers understand more. When readers read each chapter finish, reader can do Review Questions and Lab Exercises also. It's good idea when you read, you do each step from Examples (helpful more).
