Beiträge zu einem teilautomatisierten Netzmanagement für breitbandige Transportnetze

This dissertation contains contributions to the management of optical transport networks. The focus is on traffic modeling, analysis of failure mechanism, and the development of a novel semi-automatic network management system. The developed service oriented traffic models serve as input parameters for the network management system and include the special routing of the analyzed services. An evaluation system for configuration failures and a degradation model for optical network components to find failures proactively are considered to increase the resilience of transport networks. The specially developed planning process of the network management system uses the results of the analysis and the current network situation to precalculate optimal backup configurations. In the failure case the process provides either a pre-calculated optimal backup configuration or calculates with a heuristic a (sub)optimal solution.
