To propose, design, and validate a flexible optical network scenario enabling software-controlled super-channel transmission.
A novel bandwidth variable transponder (BVT) supporting 1 Tb/s multi-carrier transmission will be developed upon the BVT implementation recently presented within the EU IDEALIST project. The considered BVT will be enhanced to support, besides dynamic adaptation among different bit rates, modulation formats, spectrum allocation, and coding/FEC types, the sliceable functionality. These solutions will be assessed in terms of networking performance through specific simulative studies in the case of provisioning, elastic operations, de-fragmentation and restoration scenarios. Moreover, specifically designed control plane functionalities and advanced routing and spectrum assignment (RSA) algorithms will be proposed and experimentally validated. In particular, the control plane will rely on the GMPLS protocol suite extended for flexible optical networks and on an innovative two-level active stateful PCE implementing the new BGP-LS advertising solution. A comparative study with SDN-based solutions will also be carried out.
The REACTION project will enable R&E network providers to exploit the benefits of flexible optical networks with specific focus on sliceability and effective path computations. Moreover, the project will provide efficient solutions to cope with the expected traffic increase as well as the short-to-long term traffic variations.
