MADRID -- Telefónica I+D, R&D labs of Telefónica, one of the largest telecommunications companies in the world, and Nokia Siemens Networks have successfully tested the integration of Nokia Siemens Networks’ innovative FlexiGrid* technology with a standards-based control system for optical networks. This advanced optical architecture is based on Nokia Siemens Networks’ commercially available hiT 7300 platform. It significantly improved network efficiency, optimized capacity and throughput, and service flexibility, laying the foundation for enhanced end-user services. The trial was conducted as part of Telefónica’s Innovation Program which focuses on network evolution, and its being implemented by the Research and Development team together with the Global Chief Technology Office. Nokia Siemens Networks will demonstrate this advanced architecture at booth # 3900 at the OFC/NFOEC exhibition in Anaheim, California from March 19-21. Data traffic is increasing globally due to consumer demand for mobile video, cloud computing and other bandwidth-hungry applications and services. At the same time, traffic load is constantly changing because of varying consumer demands, making it even more difficult to predict. For global operators such as Telefónica, cost-efficient content distribution has become a priority. To address this issue, Nokia Siemens Networks integrated its FlexiGrid technology as well as its 100G technology with an optical transport control system based on GMPLS. The architecture increased spectral efficiency by 50 percent. The implementation enables the automated operation of the network and increases the reliability of service delivery as well as the flexibility of service provisioning. The test also reduced the fragmentation of the optical transport network.Nokia Siemens Networks
