Multiple user communications for telescience

Abstract

This thesis presents a software development which allows multiple users to command, control, and communicate with an experiment occurring at some distant location. These functions were implemented through the modification of software already in existence in the Telescience Laboratory. There were two important items which needed to be developed in order to accommodate the desired transition: handling multiple connections and managing user privileges. The former was implemented by the reformulation of TCP/IP protocol software. The second item necessitated the development of a key assignment scheme. Steps leading up to the final design are discussed. The software package OASIS is used throughout to constitute the user-machine interface. As an application for this multiple user technology, a simulation of a Martian oxygen production plant is commanded and controlled remotely.
