A modular format – This structure allows instructors to easily design a course to meet their individual needs. For students, it breaks this massive subject into comprehensible parts.Unifying principles – The text repeatedly emphasises such principles as multiplexing, flow control, and error control, and contrasts their application in specific areas of technology. This enables students to understand how the same protocol design principles are applied at different levels of the protocol architecture.Design Approaches – Exploring alternative approaches to meeting specific communication requirements gives students a deeper understanding of communication system and protocol design.Standards – A comprehensive discussion of the current status and future direction of related technology standards helps students understand the central role of standards in network and protocol design.More than 250 homework problems – Problems ranging in difficulty give students the opportunity to test their comprehension of concepts.Animations: Animation provides a powerful tool for understanding the complex mechanisms of network protocols. This edition incorporates a number separate animations covering such protocols as HyperText Transfer Protocol (HTTP), Simple Mail Transfer Protocol (SMTP), and Transmission Control Protocol (TCP). The text clearly indicates where the animations should be used.Strong pedagogical support – The liberal use of figures and tables; glossary; list of acronyms; recommended reading list and Websites; and a bibliography provide students with convenient study tools.

The chapter organization has been changed somewhat so that now the material is organized into two Units, with Unit Two containing more advanced material and an expansion of the material related to the Internet. Beyond this organizational revision, the most noteworthy changes include the following: Sockets Programming: A new section introduces sockets programming. Plus a number of sockets programming assignments, with sample solutions, are available for instructors.Software defined networks: A new section covers this widely used technology.Wireless transmission technology: The book provides a unified treatment of important transmission technologies for wireless networks, including FDD, TDD, FDMA, TDMA, CDMA, OFDM, OFDMA, SC-FDMA, and MIMO.4G cellular networks: A new section covers 4G networks and the LTE-Advanced specification.Gigabit Wi-Fi: A new section covers the two new Wi-Fi standards, IEEE 802.11ac and 802.11ad, which provide Wi-Fi in the Gbps range.Fixed broadband wireless access: New sections cover fixed broadband wireless access to the Internet and the related WiMAX standard.Forward error correction: Forward error correction techniques are essential in wireless networks. This new edition contains substantially expanded coverage of this important topic.Personal area networks: New sections cover personal area networks and the Bluetooth standardDynamic Host Configuration Protocol (DHCP): DHCP is a widely used protocol that enables dynamic IP address assignment. A new section covers this protocol.Datagram Congestion Control Protocol: DCCP is a new protocol that meets the needs of multimedia applications for a congestion control transport protocol without the overhead of TCP. A new section covers DCCP.Protocol Independent Multicast (PIM): PIM, the most important Internet multicast routing algorithm, is covered in a new section.Quality of service (QoS) architectural framework: A new section covers ITU-T Recommendation Y.1291, which provides an overall framework for provision of Internet QoS facilities.Electronic mail: The section on e-mail in Chapter 24 has been expanded to include a discussion of the standard Internet mail architecture.Animations: As a powerful aid to understanding the material, over 50 online animations are provided covering a wide range of topics from the book. An icon at the beginning of many chapters indicates that supporting animations are available to enhance the student's understanding.Learning objectives: Each chapter now begins with a list of learning objectives.Sample syllabus: The text contains more material than can be conveniently covered in one semester. Accordingly, instructors are provided with several sample syllabi that guide the use of the text within limited time (e.g., 16 weeks or 12 weeks). These samples are based on real-world experience by professors with the ninth edition.
