The trial, which was conducted in northern Germany as part of the IST project ONE funded by the European Union, tested the use of ROADM technology, RAYcontrol GMPLS control plane software and multi-layer configuration mechanisms to enable multi-layer restoration and automated DWDM service provisioning between IP/MPLS routers.
The trial enabled Telefonica to verify the significant potential for reduced operational and capital expenditures while driving new levels of speed and efficiency. According to Telefonica I+D analysis, multi-layer restoration led to over 37% reductions in capital expenditures in IP/DWDM networks. In addition, mean time to repair can be extended by a factor of 20 while keeping 99.999% availability, which translates to significant reductions in operating costs. However, the biggest impact was seen in the provisioning of new services.
Telefonica discovered that new services could be activated in less than 50 seconds. Previously this could take hours and was both costly and time intensive.
“The network is undergoing a huge transformation,” commented Christoph Glingener, CTO at ADVA Optical Networking. “This trial perfectly underlines the opportunities available to service providers to balance customer demand for bandwidth while at the same driving increased profitability and new business opportunities. Network automation is critical to this process and Telefonica has shown just how simple and effective unified multi-layer operations can be.”
