A world-wide known comprehensive monograph, published in 2004 by Morgan Kaufmann (an imprint of Elsevier), discusses basic principles and methods of developing optimization models for the design and management of contemporary communications networks. It is focused on the problems of traffic routing and resource dimensioning aimed at providing required service quality and network resilience. It is demonstrated how to approach those problems within an appropriate mathematical programming framework. Based on mixed-integer linear programming models and algorithms, the presented framework is applicable to modern networking technologies including IP/MPLS and DWDM/EON. The monograph is structured in a way that makes it suitable for MSc and PhD students, for researches and designers, as well as for practitioners, depending on a subset of chapters to be studied. As for January 2018, the monograph has been cited in the literature almost 1200 times.

In this paper we present an optimization platform for Fiber-to-the-Home network design. The platform is capable of minimizing CapEx, the capital expenditures of network deployment, by optimizing the location of optical equipment, signal splitters and cable cabinets, the routing and types of cables, as well as the number and types of optical cards and splitters. We present the architecture of the platform, the design process it implements, and the algorithms it deploys. The platform is used to pinpoint the parts of the design process that require careful optimization with dedicated, advanced algorithms and those that can be left to appropriately crafted engineering rules. We show that while keeping the computation time acceptable, much of the CapEx savings can be obtained when locations of optical equipment are thoroughly optimized, cable routes are determined with plain engineering rules, and finally, signal splitting patterns are optimized carefully to lower the fiber count and thus the cost of cables.
