John Day<\/span> has been involved in research and development of computer networks since 1970, when his group at the University of Illinois was the 12th node on ARPANet (precursor to the Internet) and has developed and designed protocols for everything from the data link layer to the application layer. Also making fundamental contributions to research on distributed databases. He managed the development of the OSI reference model, naming and addressing, and a major contributor to the upper-layer architecture.\u00a0 He was a major contributor to the development of network management architecture, working in the area since 1984 and building and deploying LAN products and a network management system, a decade ahead of comparable systems. Mr. Day has published Patterns in Network Architecture<\/strong><\/span>: A Return to Fundamentals<\/strong> (Prentice Hall, 2008), which has been characterized (embarrassingly) as \u201cthe most important book on network protocols in general and the Internet in particular ever written.\u201d\u00a0 The book analyzes the fundamental flaws in the Internet and proposes what appears to be the only path forward. Today Mr. Day splits his time between making this new path a reality and teaching at Boston University. Mr. Day is also a recognized scholar in the history of cartography focusing on 17th<\/sup>C China, and is past President of the Boston Map Society.<\/p>\n
