Padtec demos SDN-controlled directionless ROADM at SC14

Padtec SA, a Brazil-based optical equipment vendor and systems integrator, says its directionless reconfigurable optical add/drop multiplexer (ROADM) featured in a software-defined network (SDN) demonstration at the Supercomputing Conference 2014 (SC14) in New Orleans, LA.

Padtec participated in the "Intelligent Software Driven Dynamic Hybrid Networks With Terabit/sec Science Data Flows" demonstration by allowing a controller developed jointly by UNICAMP (a university in Campinas, Brazil), UNESP (the University of Sao Paulo, Brazil), Caltech High Energy Physics in the U.S. and CERN (the European Organization for Nuclear Research) to control its optical ROADM via its REST interface during the conference.

The network architecture deployed at SC14 highlights Padtec's efforts to advance the state of open SDN control environments, the company asserts. The three-node directionless ROADM network interworked with an application programming interface (API), which managed 100G coherent wavelength turn-up and directional control on the system.

Harvey Newman of Caltech, professor of Physics and head of the SC14 team, said, "Padtec ROADMs and software behaved perfectly. Its ROADM and 100-Gbps transponders not only allowed an astounding 1 Tbps of data to flow during SC14 but also demonstrated how an external third-party OpenDaylight controller can be used to reconfigure topology on demand and provision the individual network components."

The 100-Gbps line cards and all relevant ROADM hardware used in the demo are generally available as part of Padtec's LightPad platform, which is a carrier-class system for multi-service transport with high capacity in several network architectures.
