A distributed information system study
Klara Ziegler · IBM Systems Journal · 1979
Our study model has allowed for the testing of basic support system component functions associated with bringing up a node, connecting it with other nodes, locating and bringing up the information system components, exploring various approaches to providing distributed system control and program-to-program communication services for a distributed information system, and the testing of a dynamic network directory (or directories) atth e support systems level. The study has also provided necessary walkthroughs and paper design of information system interface and data dictionary/directory requirements. Additionally, the study has provided insights into questions associated with application programs communicating with one another, with network control services, and with node control services. Included among the questions are what to do when a failure is detected, how unsolicited messages are handled, what application program changes have to be made in order to deal with such events as responsetime fluctuations, lost responses, variable length inputs, and asynchronous request coordination.
