Computer Networks

Computer Networks: A Systems Approach, 6th Edition, is a textbook that explains networking principles through real-world systems. Using the Internet as its primary example, the book illustrates how individual network components interact within a larger, complex system.

The volume addresses foundational connectivity, internetworking, end-to-end protocols, congestion control, and resource allocation. It also examines WiFi and cellular communication, data formatting, security, cryptography, and multimedia applications.

Intended for upper-division undergraduate and graduate courses in computer science and engineering disciplines, the text also supports practicing networking professionals. Chapters include problem statements, topical sidebars, exercises, and discussions of emerging issues.
