The FlexiGrid optical architechture is based on NSN’s platform, and was integrated successfully with a standards-based control system for optical network.
“We have successfully tested Nokia Siemens Networks’ FlexiGrid transport architecture in our labs and demonstrated that Generalised Multi-Protocol Label Switching (GMPLS) based FlexiGrid networks are technically feasible,” said Juan Fernandez-Palacios, head of core network evolution at Telefónica I+D – global CTO unit.
“This is a key step to increase the efficiency and performance of our core transport networks.”
The trial was part of Telefónica’s Innovation Program focussing on network evolution and the results are hoped to respond to the increasing consumer demand for mobile, video, cloud computing and other high-bandwidth services.
“As capacity demand in backbone networks increases year by year, operators face the constant challenge of managing the growing demand cost-efficiently while maintaining service performance,” said Herbert Merz, head of Optical Networks, Nokia Siemens Networks.
“We have a long-standing relationship with Telefónica and are committed to supporting their network evolution by delivering industry-leading optical layer efficiency and flexibility while protecting their investment in the existing infrastructure.”
The trial follows NSNs recent partnership with BH Telecom to upgrade its network and provide 3G services throughout Bosnia and Herzegovina.
