15th International Conference on Optical Network Design and Modeling
Morning sessions had two main focus wireless optical networks (specially applied on access networks) and energy aware Optical Networks. On access networks the growth of fiber to the home has been mentioned in all presentations. In the paper by Visani et al. plastic optical fiber is presented as a cheap and easy to install solution for fiber to the home. The paper by Alresheedi et al. debated the advantages and drawbacks of Optical Wireless communications. One of the advantages is the fact that optical transceivers are more cost effective than radio frequency transceivers, one of the drawbacks is the degraded SNR partly due to the spread of signal receive.

In the energy efficiency topic, the investment of protection technology in PONs access network is analyzed in the paper by Mas et al. The paper by Ahmad et al. debates on the path computation process and the fact that it does not consider the physical topology and therefore does not take into account the energy expenditure. Their aim on finding a path is find the best trade-off between the utilization of electronic device for switching and optical resources for transmission: minimizing the total power consumption. They solved the problem with a Mixed Integer Linear Programming, heuristic and meta-heuristic techniques. The paper by Marcel Caria et al. presented a by-pass solution to avoid a congested IP routing link, by using a connection on the optical layer, where the only requirement is that the ingress router on the by-pass segment be configured to perform the task.
The big star of the afternoon sessions was PCE, and Hierarchical PCE. It is the technology of choice especially when multi-domain and multi-layer networks are the scenario for the attempt to provide end-to-end quality of services as it is mentioned in the article by Di Giglio et al. where the some studies from the STRONGEST project are presented. The GEYSERS project, presented by Giada Landi, focus on the control plane for the integration of dynamic optical network services in cloud computing scenarios. They propose a centralized NIPS (network and IT provisioning services) server in each network domains. DICONET project presented by Spadaro developed a Q-Tool that would be responsible for real time computation of the Q value. The MAINS project presented by Palacios focused on the control plane architectures for sub-wavelength path provision which results in a more flexible cost effective network. All the studies above propose extension on the control plane technologies as PCE and GMPLS.
