Zusammenfassung / Abstract

This work deals with the design of optical core networks based on wavelength division multiplexing. After giving an overview of fiber-optic communication technology and presenting the network architecture, we sketch the planning process. In order to solve the design problems, mathematical optimization is employed using realistic node and link models. Three specific network planning problems are investigated. First of all, redundant network topologies are calculated which are able to compensate single and dual network element failures. Our second analysis explores the total capital expenditure for an opaque and a translucent lightpath design according to a detailed cost model. The third investigation focuses on an availability-oriented routing approach which systematically adds redundant capacity to achieve a desired end-to-end availability. All approaches are demonstrated by means of typical communication networks.
