John Day Curriculum Vitae

Academic Experience

Adjunct Professor, Boston University, 2005  Teaching graduate level advanced and introductory networking and introductory Operating Systems courses.

Adjunct Professor, Worcester Polytechnic Institute, 2005 - 06.  Teaching graduate Networking course.

University of Illinois at Urbana-Champaign. 1969 – 1978Research Staff developing operating systems for the first supercomputer, ILLIAC IV and early operating systems for use with the ARPANet. Developed fundamental algorithms for updating multiple copies of databases in the face of failures, which are still applied today.

Private Sector Experience

John Day has been involved in research and development of computer networks since 1970 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 writing 3 operating systems.  Mr. Day was in charge of the development of the OSI Reference Model, Naming and Addressing and upper layer architecture and is currently 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, which included wireless subsystems. Developed plans for building Internet Service Providers (ISPs) in various parts of Europe, the Americas, and the Middle East, including all from initial business case development and funding to backbone design, service definition, deployment of infrastructure, and ISP operations.  Recently Mr. Day has been turning his attention to radically new network architectures that scale indefinitely.
