Knowledge-Based System Analysis and Control Defense Switched Network Task Areas
Abstract
Extensive modifications have been made in the existing Defense Switched Network (DSN) Call-by-Call Simulator (CCSIM) to permit its use in learning how to apply Network Management techniques in the DSN. The initial capabilities and purposes of the CCSIM are described, and the requirements for the modifications are explained. In particular, the current DSN Network Management control options are defined and explained. The upgrading of CCSIM has been completed, and some hundreds of simulation runs have been carried out and analyzed to date. In support of this analysis, it has been necessary to augment the traditional Grade of Service (GOS) measure of network performance with a pair of new measures expressing actual user experience with the net, namely Call Failure Rate (CFR) and Mean Tries for Success (MTFS). A set of basic recommendations have been derived for near-term manual DSN Network Management actions under certain failure scenarios. Concurrently, a prototype has been developed for a knowledge-based Expert System to incorporate and organize the information and techniques being gathered, so that this knowledge can be made available for reference and advice for DSN Network Managers in the field.
