Advanced dynamic migration planning toward FTTH

Abstract

This article proposes a dynamic migration planning methodology for communication networks. Aimed at providing optimal technical performance, the approach takes into account dimensioning of network infrastructure and services, as well as evaluation of revenues and costs. As a result, the migration planning method provides a cost-effective network deployment plan based on an optimal stepwise upgrade strategy. Market information, existing infrastructure, costs, and demand forecasting are then considered in order to determine this strategy by solving a combinatorial optimization problem. It is described theoretically, and a techno-economic evaluation framework is introduced to assess its financial feasibility. The model is a suitable guideline to tackle migration problems commonly solved by using anticipated, single- ,and multi-period planning techniques. Considering a particular example, a study on migration toward fiber to the home is analyzed. Fiber to the cabinet/building architectures are then proposed as possible intermediate steps in the migration path to fiber to the home. Finally, a case study for an existing access network is analyzed.
