Computer Networks: A Systems Approach is a carefully focused revision of the best-selling first edition, updated to incorporate user feedback and reflect the most recent changes in networking technology.

Inside, a systems approach focused on the Internet promotes an enduring, practical understanding of networks and their building blocks. Each chapter begins with the statement of a problem that frames the following discussion. The authors then develop complete solutions, illustrate them with real-world examples—including specific protocol references and C code—and address topical issues debated throughout the networking community.

The result? Readers learn the why of network design—not just the facts surrounding current systems but the principles at work in their application and evolution. No other textbook offers a more solid grounding or better preparation for a career in networking.
