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
