In this paper we study the cost-optimal deployment of optical access networks considering variants of the problem such as fiber to the home (FTTH), fiber to the building (FTTB), fiber to the curb (FTTC), or fiber to the neighborhood (FTTN). We identi

Smart cities will be characterized by a variety of intelligent and networked services, each with specific requirements for the underlying network infrastructure. While smart city architectures and services have been studied extensively, little attent

Traffic in communication networks fluctuates heavily over time. Thus, to avoid capacity bottlenecks, operators highly overestimate the traffic volume during network planning. In this article we consider telecommunication network design under traffic

In this article, we study capacitated network design problems. We unify and extend polyhedral results for directed, bidirected, and undirected link capacity models. Valid inequalities based on a network cut are known to be strong in several special c

Given a general mixed integer program, we automatically detect block structures in the constraint matrix together with the coupling by capacity constraints arising from multi-commodity flow formulations. We identify the underlying graph and generate

In this paper, we evaluate the cost of wireless integration into an architecture based on long reach passive optical networks (LR-PON). We will demonstrate that including backhaul or fronthaul signals from antenna sites into existing LR-PON structure

In this paper we first report on an optimization process for assessing the sensitivity on CAPEX of the most important parameters of IP-aggregation / IP-core and WDM transport networks. We then combine resulting transport network topologies with conte
