Spanish telecommunications provider Telefónica and Chinese smartphone maker Huawei have successfully completed the laboratory tests on the T-SDN (Transport Software-Defined Network) solution, a controller which incorporates improvements for the planning, management, monitoring and diagnosis of Telefónica España’s photonic mesh.

According to a joint press release, the tests on this new software solution to improve network operations in the photonic mesh, whereby the communication is all optical to transport large volumes of data by light, entail the creation of a solid basis for the commercial deployment of T-SDN.

In 2009, Telefónica began deploying its largest photonic mesh network, covering more than 200 locations throughout Spain.

In 2009, Telefónica began deploying its largest photonic mesh network, covering more than 200 locations throughout Spain. This network used the flexible ROADM (Reconfigurable Optical Add/Drop Multiplexer) technology and an advanced network control plane. This improved the reliability and flexibility of the service and also posed challenges for Operation and Maintenance (O&M).

To address these challenges for O&M related to the national photonic mesh, Telefónica has tested the benefits of the T-SDN solution with Huawei. The new centralized controller developed by Huawei can be used as the network’s brain to obtain real-time information and to use online incident simulations to compile reliable information on the service, the press statement notes. The aims are to rapidly identify the risks to the service and to prevent potential network incidents by means of this technology.

The centralized T-SDN algorithm can also be used to optimize the spectrum and to improve the reliability and performance of the new WDM (Wavelength Division Multiplexing) networks.

“Huawei continues to lead the global deployment and use cases of T-SDN. This solution has been implemented in more than ten networks for customers in different countries …”. Richard Jin, President of Transmission at Huawei, said. “Huawei will continue its close cooperation with Telefónica to reinforce its transport network and to provide the best service experience in Spain”.
