 Project:
 New Perspectives for the Switching Paradigms on New Generation
Optical Networks:
Abstract: This research project aims to expand the studies in the area of Optical Networks, focusing on new
perspectives for the switching paradigms that are likely to be present in the next generation of optical networks.
Therefore, the main objective of this project is to analyze hybrid networks operating with different switching
paradigms, using for this goal the ONSim platform, developed in our research group. Thus, we are intended to
enable the simulation of hybrid optical networks with multiple switching paradigms, which will be studied in a
variety of scenarios.
 Start: March, 01.

Optical Networks with Multiple Optical Switching Paradigms  Project:  New Perspectives for the Switching Paradigms on New Generation Optical Networks: Abstract: This research project aims to expand the studies in the area of Optical Networks, focusing on new perspectives for the switching paradigms that are likely to be present in the next generation of optical networks. Therefore, the main objective of this project is to analyze hybrid networks operating with different switching paradigms, using for this goal the ONSim platform, developed in our research group. Thus, we are intended to enable the simulation of hybrid optical networks with multiple switching paradigms, which will be studied in a variety of scenarios.  Start: March, 01. 23 Grant: 2013/24247-5Grant 306153/2013-0
