Computer Networking

For Introduction to Networking courses.

A proven top-down, layered approach to computer networking

Computer Networking introduces this complex subject in a top-down manner, proceeding from the application layer toward the physical layer and motivating students with important concepts early in their study. While more precise and analytical than other texts, its clear and accessible presentation helps students build a solid foundation without extensive prior knowledge of programming or mathematics.

The 9th Edition addresses the introduction of Wi-Fi-6, 5G cellular networks, and the software-i-zation of cellular networks, all of which have driven more rapid change in wireless and mobile networking since the previous edition. It also updates many sections throughout to reflect changes across the breadth of networking. Revisions include new coverage of HTTP/3 protocol and QUIC, new material on content distribution networks and streaming services, updated discussion of network security, and much more.
