TL;DR: Experiments show that a careful dimensioning and location of the nodal equipment can save up to 60% of the number of photonic cross-connects (PXCs), and even more sometimes.
Abstract: The focus of this paper is on the minimum cost resource provisioning and nodal equipment location PROVLOC problem for Wide Area Networks (OWANs), i.e., optical networks that cover broad areas. Minimizing the cost means minimizing the network capital and operational expenditures throughout the dimensioning of the nodal equipment, and the location of all-optical cross-connects, while granting all traffic requests. This is done thanks to large scale modeling and optimization tools relying on a scalable column generation method and an efficient rounding off heuristic. Experiments on various network and traffic instances show that a careful dimensioning and location of the nodal equipment can save up to 60% of the number of photonic cross-connects (PXCs), and even more sometimes.

TL;DR: In this article, the authors demonstrate potential cost savings by placing electrical grooming crossconnects into a core network consisting predominantly of optical cross-connects while simultaneously improving bandwidth utilisation, relaxing unregenerated distance/hop count and lowering network capacity requirements.
Abstract: We demonstrate potential cost savings by placing electrical "grooming" cross-connects into a core network consisting predominantly of optical cross-connects while simultaneously improving bandwidth utilisation, relaxing unregenerated distance/hop count and lowering network capacity requirements.

TL;DR: Planning rules and a mathematical model are introduced which can enable network planners, from day one, to optimally dimensioning GPON access network resources (PON link capacity, OLT's ports, splitter's ports).
Abstract: A dimensioning process of Gigabit Passive Optical Network (GPON) involves the selection of a split ratio that determines the allocated bandwidth per subscriber sharing a single passive optical network (PON) link (Optical Line Terminal (OLT) port). The selection of a small split ratio can be costly, whereas the selection of a higher split ratio can reduce the bandwidth allocated per subscriber and subsequently subscribers may quickly experience less quality in provisioned services. This paper aims to introduce planning rules and a mathematical model which can enable network planners, from day one, to optimally dimensioning GPON access network resources (PON link capacity, OLT's ports, splitter's ports). The mathematical model considers four parameters for optimal dimensioning GPON access network: Number of subscribers and their type, busy hour, service penetration rate and bandwidth requirement. The planning rules and mathematical model have been integrated into a software utility which we have developed to evaluate the support of next-generation services in GPON access network.

TL;DR: In this paper, the authors addressed some issues on the modeling of an optical network working with hybrid-switching paradigms, and proposed a hybrid switching paradigm for the optical network.
Abstract: The continuous increasing of the Internet traffic has brought serious concerns about capacity exhaustion of the optical infrastructure in a medium term horizon. Taking into account the optical networks, comprising the Internet backbone, the strategies to avoid this catastrophic scenario point to the development of new technologies that enable the capacity expansion, as well as to a better utilization of network resources (spectrum or wavelengths). The elastic optical network, considered as a realistic perspective for the infrastructure, optimizes the required spectrum and improve the efficiency of resources utilization. However, it is based on optical circuit switching paradigm that tends to waste resources due to idle times of reservation process. Since in some dedicated optical networks, like data center networks, certain optical switching paradigms have become reality, it is expected that in the coming years not only an elastic optical network, but also a hybrid network, in terms of switching paradigms, be brought to reality. Considering this scenario, the present paper addresses some issues on the modeling of an optical network working with hybrid-switching paradigms.
