Workshop on “Network Optimization“ (NeO)
Cartagena, Spain, June 23-27, 2013
Scope: The exponential growth of IP traffic imposed by new Internet applications makes network operators face new challenges in providing cost‐effective high‐speed data transmission. Since essentially IP networks are supported by optical-based core networks, important requirements for those optical networks are, among others, capability to (i) accommodate sub‐wavelength client flows, (ii) guarantee the required availability, quality of transmission, and quality of service, iii) manage resources in an elastic way to adjust used resources to fit variable requests.
All those requirements must be performed with minimum capital and operational expenditures (including energy), and under demand uncertainty. In fact, the use of control planes automatically establishing and releasing connections leads to non-optimal utilization of network resources so that some kind of optimization, be it an off-line and/or on-line optimization, must be applied to enhance the effectiveness of the utilization in question.
Recent advances in high performance computer architectures such as many-core processors potentially enable obtaining exact and near-optimal solutions to the above mentioned optimization problems in acceptable time, so that developing planning/ optimization tools to be used within operating networks becomes feasible.
Topics include but are not limited to:
- Linear and non-linear programming models for elastic optical communication networks
- Concurrent optimization
- Stochastic and robust optimization
- Decomposition, relaxations, and column generation techniques
- Branch-and-cut, branch-and-price, and cutting-plane methods
- Heuristics and meta-heuristics for near optimal solutions
- Implementation issues in high-performance computer architectures
