Abstract:

This report documents the results of a twelve month study of routing and control techniques to enhance the survivability and performance of circuit switched networks. Major emphasis has been placed on the investigation of European Autovon with respect to given scenarios and control actions. A primary and significant output of this study has been a fast, flexible hybrid computer simulation program. This call-by-call simulation incorporates five-level priority calling, four-level preemption, and scenariocontrol action mechanisms. The network chosen for this study was a 10 node network similar to the European Autovon with the Conus Gateway switches modeled as one additional node. Twenty-six links were simulated including the three Conus Gateway links. Original capacity of the model was 15 nodes including the Conus Gateway node and 48 links. Calls were generated on a call-by-call basis using actual traffic loading data from the European Autovon to drive nonlinear functions for call hold times and time between calls.
