Abstract
Testing of Network Management Systems usually involves constructing replicas of the actual networks (`captive offices') which are both costly and cumbersome. In this paper a novel approach is presented which allows alarm messages to be generated and propagated within Synchronous Digital Hierarchy (SDH) networks in `real-time'. The development of the models using a commercial event-driven simulation package is described. Simulation results are presented which reveal how differing network sizes, configurations and alarm masking strategies can affect the number and type of alarm messages presented to the network management system. The models were interfaced to a `live' Element Manager, which allowed them to be verified by comparing to a fully-configured physical network, and which allowed testing of a Network Management System. Some work on enhancing the real-time models using timing information from VHDL descriptions of the Network Equipment is also presented.
