Telefónica I+D, the R&D labs of Telefónica, has successfully tested the integration of Nokia Siemens Networks’ FlexiGrid technology with a standards-based control system for optical networks.
NSN's FlexiGrid is based on the company's hiT 7300 DWDM platform. To increase network efficiency, Nokia Siemens Networks integrated its FlexiGrid technology as well as its 100G technology with an optical transport control system based on GMPLS. The company said its 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.
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.
“We have successfully tested Nokia Siemens Networks’ FlexiGrid transport architecture in our labs and demonstrated that Generalized Multi-Protocol Label Switching (GMPLS) based FlexiGrid networks are technically feasible. This is a key step to increase the efficiency and performance of our core transport networks,” said Juan Fernandez-Palacios, head of Core Network Evolution at Telefónica I+D Global Chief Technology Office unit.”
On December 3, 2012, Nokia Siemens Networks and Marlin Equity Partners announced that they had reached an agreement for Nokia Siemens Networks to sell its Optical Networks business unit to Marlin Equity Partners. The announcement outlined that the deal would result in the unit being established as an independent company with the goal of becoming a leading provider in the optical market.
