Book Description

Addressing the fundamental technologies and theories associated with designing complex communications systems and networks, Principles of Communications Networks and Systemsprovides models and analytical methods for evaluating their performance. Including both the physical layer (digital transmission and modulation) and networking topics, the quality of service concepts belonging to the different layers of the protocol stack are interrelated to form a comprehensive picture.

The book is designed to present the material in an accessible but rigorous manner. It jointly addresses networking and transmission aspects following a unified approach and using a bottom up style of presentation, starting from requirements on transmission links all the way up to the corresponding quality of service at network and application layers. The focus is on presenting the material in an integrated and systematic fashion so that students will have a clear view of all the principal aspects and of how they interconnect with each other.

• A comprehensive introduction to communications systems and networks, addressing both network and transmission topics
• Structured for effective learning, with basic principles and technologies being introduced before more advanced ones are explained
• Features examples of existing systems and recent standards as well as advanced digital modulation techniques such as CDMA and OFDM
• Contains tools to help the reader in the design and performance analysis Download Now »

Book Description

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
