Abstract

Security measures are being applied in the Telecom Eireann trunk telephone network to minimise disruption due to excess traffic or system failure. Dynamic measures, such as network management, will be deployed in the very near future, but in the meantime static measures are being applied. Geographically separate exchanges of the same status are provided at major nodes with traffic shared equally between them on separate transmission links. Rerouting is provided automatically when a system fails, but at a reduced grade of service. The paper presents a model which simulates this concept of mutual alternative routing using the UNIX-based OPNET (Optimised Network Engineering Tools) package
