Network planning is critical to the performance, reliability and cost of web services. This
problem is typically formulated as an Integer Linear Programming (ILP) problem. Today's …

In this paper we propose an optimization framework for multiple deployment of PON in a
wide region with very large number of users, with different bit rate demands, serviced by …

In this work, we focus on the problem of virtual machines (VMs) placement in geographically
distributed data centers. We consider communicating VMs assigned to data centers that are …

To cope with the capacity increase and diversification of information services, enhancing
efficiency, flexibility, and agility in optical transport networks is becoming increasingly …

Topology Bench is a comprehensive topology dataset designed to accelerate benchmarking
studies in optical networks. The dataset, focusing on core optical networks, comprises …

In this paper, we provide some analytical insights into physical architectures that can serve
as benchmarks for designing a cost-efficient WDM metropolitan area network (MAN). For …

Optical grids are widely deployed to solve complex problems we are facing today. An
important aspect of the supporting network is resiliency ie the ability to overcome network …

Grids use a form of distributed computing to tackle complex computational and data
processing problems scientists are presented with today. When designing an (optical) …

This work presents joint optimization algorithms for lightpath establishment as well as sparse
placement of optical performance monitoring (OPM) equipment in optical networks. OPMs …

In this paper we consider a capacity sizing and routing problem in synchronous digital
hierarchy/wavelength division multiplexing networks with nodes having switching …
