An experimental overview on software defined optical transmission and sdngmpls networking activities in the adrenaline testbed
1 like•1,886 views
- An experimental testbed called ADRENALINE is evaluating software-defined optical transmission and SDN/GMPLS networking. - The testbed includes a programmable OFDM transponder for software-defined optical transmission, a 4-node mesh network with fiber links of varying lengths, and emulation of SDN/OpenFlow and GMPLS control planes. - Experiments are exploring flexible-grid optical networks using OFDM, all-optical OSNR estimation, and a sliceable bitrate-variable transponder as a building block for future software-defined optical networks.
