Mr. John D Day

John Day has been involved in research and development of computer networks since 1970 (his original network address was 12) when he was involved in the design of transport and upper layer protocols for the ARPANet as well as the Internet. Mr. Day has developed and designed protocols for everything from the data link layer to the application layer. Mr. Day has made fundamental contributions to research on distributed databases developing one of two fundamental algorithms in the updating of multiple copies. He also did work on the early development of supercomputers and was a member of a team in developing 3 operating systems. Mr. Day was an early advocate of the use of Formal Description Techniques for protocols and shepherded the development the three international standard FDTs: Estelle, Lotos, and SDL. Mr. Day was in charge of the development of the OSI Reference Model, Naming and Addressing and a major contributor to the upper layer architecture and was a member of the Internet Research Task Force’s Name Space Research Group. He has been a major contributor to the development of Network Management Architecture, working in the area since 1984 defining the fundamental architecture currently prevalent and designing high performance implementations, and fielded a network management system in the mid-80’s that was 10 years ahead of comparable systems. Mr. Day was also involved in the development of the Utilities Communication Architecture for electric, gas, and water utilities; and in the design and deployment of field trials for various utilities. Recently Mr. Day has been turning his attention to radically new network architectures that scale indefinitely as described in his recent book Patterns in Network Architecture: A Return to Fundamentals. Mr. Day is also a recognized scholar in the History of Cartography having published on topics relating to Neolithic Korea and to the Jesuits in 17thC China. Most recently, Mr. Day has contributed to an exhibit, Encompassing the Globe, at the Smithsonian Institution, summer 2007 and a chapter in Matteo Ricci Cartographia in Italian.
