Project STIC-AMSUD ACCON

Algorithms for the Capacity Crunch problem in Optical Networks.

Summary:The ACCON project focus on developing new strategies to efficiently manage the network resources in the optical networks’ area, based on the Elastic Optical Networks’ (EON) architecture and the Space-Division Multiplexing (SDM) Wavelength Division Multiplexing (WDM) technology. These resources are bandwidth, frequency spectrum, wavelengths, installed fiber cables add/drop switch ports, among others. Associated with these global goals, the project will also propose new methods to design elastic optical networks and SDM-based optical networks. These objectives also include solving several important problems such as routing, spectrum dimensioning, wavelength dimensioning, defragmentation techniques, fault tolerance strategies, etc. Additionally, all these problems must be solved considering a simple network operation to be deployed by the ISPs. Last, associated with previously described tasks, it is critical to be able to guarantee statistically a minimum quality of service based on the obtained performance of these EON and SDM WDM optical communication systems.
