John Day
Master Lecturer, Computer Science
John Day 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. Along with making fundamental contributions to research on distributed databases, Mr. Day managed the development of the OSI reference model as well as naming and addressing. He was a major contributor to the upper-layer architecture and 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. Day has published Patterns in Network Architecture: A Return to Fundamentals (Prentice Hall, 2008), which 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. He is also a recognized scholar in the history of cartography, focusing on seventeenth-century China, and is past president of the Boston Map Society.
