In this paper, for calculating the amount of cable and fibre in the outside plant together with the associated civil works, and the number of required network elements, two different approaches are investigated: 1 geometric modelling of the fibre plant based on approximate mathematical models and 2 geographic modelling of the fibre plant based on map-based geospatial data. Compared to more complex and accurate geographic modelling, we verify that especially with uneven population density and irregular street system, simple geometric models do not provide accurate results.

However, if no geospatial data is available or a fast calculation is desired for a first estimation, geometric models definitely have their relevance. Based on the case studies presented in this paper, we propose some important guidelines to improve the accuracy of the geometric models by eliminating their main distortion factors.

Mitcsenkov, M. Kantor, K. Casier, B. Lannoo, K. Wajda, J. Chen, L. Next Generation Access NGA networks offer enormous bandwidth and low latency, mainly due to the exploitation of optical transmission. Deploying optical fiber in the access network, however, requires a huge investment, therefore optimization of the physical infrastructure plays an important role.

In the recent years, algorithmic access network design became viable, mainly due to the existence of digital maps and Geographic Information System GIS databases. In this paper, we present a novel technology-independent solution based on the Simulated Annealing SA metaheuristics for tree-based point-to-multipoint optical access network topologies.

The key for scalability is the concept Voronoi-diagrams applied for demand point clustering and evaluation within the Simulated Annealing scheme. We present a topology design methodology for broadband FTTx access networks. The calculations are based on real geographic data digital maps and infrastructural information of the targeted area, using detailed and realistic cost models in order to provide results of practical interest. The developed heuristics offer low time consumption and nearly optimal solutions for the highly complex problem of minimal cost network deployment, due to the properly chosen and customized heuristic algorithms for the various network technologies.

We review the specific properties of the FTTx network technologies, present a formal representation of the problem including a detailed cost function and network model and discuss complexity issues. The various solution techniques are presented along with case studies of real-life scenarios in order to show the potential of the methodology.

Beyond topology design, the results provided by these methods are useful for a preliminary CAPEX estimation and techno-economic comparison. Mitcsenkov, G. Paksy, T. Photonic Network Communications, Vol. Several mature and standardized optical access network technologies are available for network operators providing broadband services, being now in deployment phase; therefore cost estimation, business analysis, efficient deployment strategies, network and topology design issues for FTTx access networks play an increasingly important role regarding profitability and market success.
