About the Authors
Benoît Claise, CCIE No. 2686, is a Cisco Fellow, working as an architect for embedded management. Areas of passion and expertise include Internet traffic monitoring, accounting, performance, fault, and configuration management. Benoît’s area of focus these days is network automation with YANG as the data modeling language, NETCONF/RESTCONF, and telemetry as a feedback loop to solve intent-based networking.
Benoît was IETF Operations and Management Area (OPS) co-director from 2012 to 2018, a period during which much of the data model–driven management protocols, encoding, and data models were specified. He blogs on these topics on his web site http://www.claise.be/ and spends time on the yangcatalog.org developments.
Benoît is a contributor to the IETF, with 35 RFCs in the area of NetFlow, IPFIX (IP Flow Information eXport), PSAMP (Packet Sampling), IPPM (IP Performance Metrics), YANG, MIB module, energy management, and network management in general. Benoît is the co-author of the Cisco Press book Network Management: Accounting and Performance Strategies.
As a Cisco Customer Experience Engineer, Joe Clarke, CCIE No. 5384, has contributed to the development and adoption of many of Cisco’s network management and automation products and technologies. He helps to support, enhance, and promote the embedded automation and programmability features, such as the Embedded Event Manager, Tcl, Python, NETCONF/RESTCONF, and YANG.
Joe evangelizes these programmability and automation skills in order to build the next generation of network engineers. He is a Cisco Certified Internetworking Expert and certified Cisco Network Programmability Engineer. Joe has authored numerous technical documents on Cisco network management, automation, and programmability products and technologies, as well as a chapter as co-author of Network-Embedded Management and Applications: Understanding Programmable Networking Infrastructure. He also served as one of the technical editors for the Cisco Press books Tcl Scripting for Cisco IOS and Programming and Automating Cisco Networks: A Guide to Network Programmability and Automation in the Data Center, Campus, and WAN. He is an alumnus of the University of Miami and holds a Bachelor of Science degree in computer science.
Outside of Cisco, Joe is a member of the FreeBSD project and the co-chair of the Ops Area Working Group at the IETF. Joe is a certified commercial pilot for single-engine airplanes with an instrument rating. He lives with his beautiful wife in the RTP area of North Carolina.
Jan Lindblad soldered together his first computer at age 12, wrote his first compiler at 16, and reached the million lines of code mark by 30. In 2006, when NETCONF was first published by IETF, Jan was at the then newly founded start-up company Tail-f Systems. Tail-f built the first commercial implementation of NETCONF and was a driving force behind the introduction of YANG.
Jan is an IETF YANG Doctor and has also authored and reviewed many YANG modules in other organizations. Jan has trained several hundred people on the theory and practice of NETCONF and YANG. At the yearly NETCONF/YANG interop event organized by EANTC in Berlin, Germany, Jan plays a central role.
Outside Cisco, Jan is an avid climate activist and environmentalist. He lives outside Stockholm, Sweden, and commutes to work by bike every day.
About the Technical Reviewers
Peter Van Horne attended the University of Michigan, in Ann Arbor, Michigan, graduating in 1977 with a B.S in computer engineering. He joined Cisco in 2000 through the acquisition of startup CAIS Software, which provided software- and systems-enabling public Internet access in airports, hotels, and other public places. He is a Principal Engineer at Cisco, leading projects such as YANG model-based programmatic interface development for multiple Cisco product lines. Peter is a holder of multiple patents in communications and Internet-related applications.
Warren Kumari, CCIE No. 9190, is a Chief Retro-Phrenologist/Senior Network Security Engineer with Google, and has been with the company since 2005.
