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.
