Abstract

Most telecom operators have to plan the migration of their existing copper networks to full or hybrid fibre networks, to offer their clients the bandwidth they require. This paper
proposes methods to optimise this migration path, heterogeneously per central office area, using geometric models as input. The methods result in a detailed migration path that meets a required bandwidth coverage, installation capacity and/or budget constraint. To solve the optimisation problem in an efficient way, both a problem-based solution method and a simulated annealing approach are tested for scalability of the problem solving. As the data used for the migration path optimisation is in practice
hard to gather, the use of geometric modelling is proposed. This modelling approach leads to the optimal migrating path, estimating the total initial investment of a migration step using only two simple parameters per Central Office area.
