End-to-End QoS Network Design

Quality of Service for Rich-Media & Cloud Networks Second Edition

New best practices, technical strategies, and proven designs for maximizing QoS in complex networks

This authoritative guide to deploying, managing, and optimizing QoS with Cisco technologies has been thoroughly revamped to reflect the newest applications, best practices, hardware, software, and tools for modern networks.

This new edition focuses on complex traffic mixes with increased usage of mobile devices, wireless network access, advanced communications, and video. It reflects the growing heterogeneity of video traffic, including passive streaming video, interactive video, and immersive videoconferences. It also addresses shifting bandwidth constraints and congestion points; improved hardware, software, and tools; and emerging QoS applications in network security.

The authors first introduce QoS technologies in high-to-mid-level technical detail, including protocols, tools, and relevant standards. They examine new QoS demands and requirements, identify reasons to reevaluate current QoS designs, and present new strategic design recommendations. Next, drawing on extensive experience, they offer deep technical detail on campus wired and wireless QoS design; next-generation wiring closets; QoS design for data centers, Internet edge, WAN edge, and branches; QoS for IPsec VPNs, and more.

This book is part of the Networking Technology Series from Cisco Press®, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

Tim Szigeti, CCIE No. 9794, is a senior technical leader in the Systems Design Unit at Cisco Systems, where his role is to design network architectures for enterprise mobility solutions. He has specialized in quality of service technologies for the past 15 years, during which time he has authored many technical papers, design guides, and two Cisco Press books: End-to-End QoS Network Design (version 1) and Cisco TelePresence Fundamentals.

Robert Barton, CCIE No. 6660, is located in Vancouver, where he lives with his wife and two children. He graduated from the University of British Columbia with a degree in engineering physics, and is a registered professional engineer. Rob holds dual CCIEs, in Routing and Switching and Security, and was also the first CCDE in Canada. Rob joined Cisco from ArrowPoint Communications, where he worked as a data center specialist supporting many of the largest corporations in Canada. In the time since ArrowPoint was acquired by Cisco, Rob has worked as a public sector systems engineer, primarily focused on wireless and security architectures. Currently, Rob is working on SmartGrid network technologies, including smart meter and intelligent substation design.

Christina Hattingh spent 13 years as a senior member of the technical staff in Unified Communications (UC) in the Enterprise Networking Routing Group (formerly Services Routing Technology Group or SRTG) at Cisco Systems. The SRTG products, including the Cisco 2900/3900 and 2800/3800 series ISR platforms and their predecessors, were the first Cisco platforms to converge voice, data, and video traffic and services on IP networks by offering TDM gateway interfaces, WAN interfaces, call control, and QoS features. The ISR series of routers often live at smaller remote offices and therefore at the edge of the WAN, where the need for QoS services is most sensitive. In this role, Christina spoke at Cisco Live conferences, trained Cisco sales staff and Cisco resale partners on router-based UC technologies, authored several Cisco Press books, and advised customers on UC network deployment and design, including QoS designs and helping them through the TDM to SIP trunk industry transition.

Kenneth Briley, Jr., CCIE No. 9754 is a technical lead in the Network Operating Systems Technology Group at Cisco Systems. For over 10 years, he has specialized in quality of service design and implementation in customer environments, alignment of QoS features and functions, and the marketing of new products that leverage QoS technologies. During this time, he has written several deployment guides and whitepapers, presented at Cisco Live, and most recently has focused on the convergence of wired and wireless quality of service.
