	abstract = {We present 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, discuss complexity issues. The various solution techniques are presented along with case studies of real-life scenarios, in order to show potential of the methodology. The developed heuristic algorithms offer approximation of the optimum within 10-15%, while time consumption remains in the range of a few minutes even for large-scale scenarios with 10.000s of customers. Beyond topology design, the results provided by these methods are useful for preliminary CAPEX estimation and techno-economic comparison.},

FTTx technologies are now mature and standardized; network deployment phase has already started in many areas around the world.
		The profitability of such an optical broadband access technology strongly depends on the design of optimal topologies, minimizing initial investments (CapEx). The network planning problem itself is difficult (NP-hard), however close to optimal topologies are required even for large data sets, for city-scale service areas.
		Therefore efficient heuristic approximations are needed, like the Branch Contracting Algorithm (BCA) presented in this paper. It can handle real problem instances, provides close to optimal solution, and works fast enough to support economic comparison of different architectures, supporting decisions of a network operator.},

These technologies are now in deployment phase, therefore network and topology design issues play an increasingly important role. In this paper we address broadband optical access network design minimizing deployment costs, taking operation issues into account, using detailed cost and network models of the above listed FTTx technologies that suit best to actual networks due to detailed cost metrics used instead of just minimizing fiber lengths. We present a heuristic solution that works fast even for large problem instances, providing results with a difference less than approximately 10-20% from the computed ILP (Integer Linear Programming) optimum for smaller cases where ILP could be used. Along with these algorithms we present case studies of real-life network and service requirement instances (number of customers ranging from 400 to 20.000).},
