The OMEGA test-bed is used to
test and validate the effectiveness and assess the performance of
the concepts developed within the lab activities. The need for a test-bed
raised after the promising results obtained in the NSF project "Differentiated
Reliability (DiR) in Multi-Layer Optical Networks". The studied concepts were
succesfully transferred to the test-bed and further extended thanks to the collaboration
with CPqD research team.
The test-bed consists
of 6 nodes connected to form a mesh (general) topology. Each node
consists of a PC running Linux that is used to implement the control
plane of the Optical Layer. The Optical Layer is emulated by a dedicated
PC that will provide information about the status of the optical
components. The interface between the PCs running the control plane
and the PC emulating the Optical Layer will be realized using parallel
ports. This interface will allow the control plane to both gather
information regarding the status of the Optical Layer (e.g., fiber
cut, signal degradation) and control the setup of the optical components
(e.g., optical cross-connect). Connections between PCs running the
control plane are realized using 100Mb/s Fast Ethernet interfaces.
Emulation of the Optical Layer enables to apply the implemented
control plane functionalities to a wide range of emulated optical
cross-connect technologies and platforms.
Additionally, the ongoing collaboration with the CPqD will enable
to test part of the developed concepts on their optical test-bed.
