COMPUTER NETWORKS. A systems approach, Second Edition (Broché)

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. A systems approach focused on the Internet promotes an enduring, practical understanding of networks and their building blocks. Each chapter begins with a problem statement that frames the discussion to follow. 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.
