In this new edition of their classic and bestselling textbook, authors Larry Peterson and Bruce Davie continue to emphasize why networks work the way they do. Their "system approach" treats the network as a system composed of interrelated building blocks (as opposed to strict layers), giving students and professionals the best possible conceptual foundation on which to understand current networking technologies, as well as the new ones that will quickly take their place.Incorporating instructor and user feedback, this edition has also been fully updated and includes all-new material on MPLS and switching, wireless and mobile technology, peer-to-peer networks, Ipv6, overlay and content distribution networks, and more. As in the past, all instruction is rigorously framed by problem statements and supported by specific protocol references, C-code examples, and thought-provoking end-of-chapter exercises.Computer Networks: A Systems Approach remains an essential resource for a successful classroom experience and a rewarding career in networking. - Written by an author team with over thirty years of first-hand experience in networking research, development, and teaching--two leaders in the work of defining and implementing many of the protocols discussed in the book. - Includes all-new coverage and updated material on MPLS and switching, wireless and mobile technology, peer-to-peer networks, Ipv6, overlay and content distribution networks, VPNs, IP-Telephony, network security, and multimedia communications (SIP, SDP). - Additional and earlier focus on applications in this edition makes core protocols more accessible and more meaningful to readers already familiar with networked applications. - Features chapter-framing statements, over 400 end-of-chapter exercises, example exercises(with solutions), shaded sidebars covering advanced topics, web resources and other proven pedagogical features.

Larry Peterson is the Robert E. Kahn Professor of Computer Science, Emeritus at Princeton University, where he served as Chair from
2003-2009. His research focuses on the design, implementation, and operation of Internet-scale distributed systems, including the widely used PlanetLab and MeasurementLab platforms. He currently serves as the CTO of the Open Networking Foundation (ONF), where he works on open source software at the intersection of access networks and the edge cloud. Professor Peterson is a member of the National Academy of Engineering, a Fellow of the ACM and the IEEE, the 2010 recipient of the IEEE Kobayashi Computer and Communication Award, and the 2013 recipient of the ACM SIGCOMM Award. He received his Ph.D. degree from Purdue University in 1985.
