• The text goes beyond the basic topology and switch operation to cover topics such as link aggregation, the Rapid Spanning Tree Protocol, and more.

• The latest in networking techniques and wireless networking are discussed, including a focus on security.

Keeps students up-to-date with new material and chapter updates

• Updated - Now the Internet is discussed before single networks, and speed details were moved to Chapter 3 to provide a cleaner flow of material.
• Updated - Cloud computing was moved to Chapter 11 because it primarily deals with application architecture.
• Updated - The syntax of HTTP has been moved entirely to Chapter 11, the Networked Applications chapter.
• Updated - Chapter 2 discusses the Ethernet II frame, not the 802.3 MAC Layer frame. Now that IP dominates at the Internet layer, it is Ethernet II frames that students have to understand.
• Updated - Chapter 3 now includes network management information and centralises SDN information, which was spread across multiple chapters in the previous edition.
• Updated - Everything in Chapter 4 has been updated, and the stateful inspection and next-generation firewall sections have been considerably redone.
