Explains routing algorithms, congestion control, Quality of Service (QoS), and the transition between IPv4 and IPv6.
Focuses on protocol principles, error detection and correction, and flow control (e.g., sliding window protocols). Andrew S Tanenbaum Computer Networks 4th Edition Pdf
The book is organized according to a bottom-up model, starting from hardware and moving toward high-level applications: Compared to previous versions
Material on older, obsolete LAN and WAN protocols that were no longer in widespread use by 2003 was significantly reduced. 2G/3G cellular networks
Compared to previous versions, this edition introduced significant updates to reflect the technology landscape of the early 2000s:
Extensive new material was added for 802.11, 2G/3G cellular networks, and ad hoc networking.
Tanenbaum’s work is highly regarded for its "software-oriented" perspective, making it a standard for computer science students who need to understand how to build and maintain network software rather than just hardware. The text is frequently used for academic courses and includes approximately 250 exercises and a protocol simulator for practical testing.
