SENDATE, the Celtic-Plus flagship project for secure networking of data centers in Europe, today announced successful completion of an industry-first multi-vendor SDN field trial featuring real-time planning of transparent high-speed services across a disaggregated, multi-domain optical network. The SENDATE trial showcased the critical role that standards-based SDN interworking and integrated planning play in simplifying operations and reducing end-to-end provisioning times in multi-domain, disaggregated optical networks.
Conducted this month in the Telia Company R&D lab in Stockholm with live connectivity to production network fibers, the multi-vendor, multi-domain trial included participation from optical networking and SDN solution suppliers and research partners, including ADVA, Coriant, highstreet technologies, VPIphotonics, and the RISE Research Institutes of Sweden.
As new high-bandwidth end-user applications drive increased demand for photonic layer connectivity, service providers face the real-world challenge of provisioning across multi-vendor optical networks.
Based on the SENDATE SDN control architecture, the multi-vendor trial configuration was designed to demonstrate end-to-end wavelength service activation between disaggregated transponders spanning SDN-enabled ADVA and Coriant optical domains. Use cases tested during the trial included dynamic optical reach planning using open APIs and SDN-enabled 100Gbit/s and 200Gbit/s alien wavelength provisioning across multi-vendor optical domains. The successful interworking leveraged an extension of the standardized ONF T-API interface significantly enhanced and extended with optical impairment capabilities for automated network planning. The SDN controller was based on OpenDaylight with an integrated photonic planning app running as a micro-service.
This work has been performed in the framework of Celtic-Plus project SENDATE by the sub-projects SENDATE-Secure-DCI and SENDATE-FICUS, and it is partly funded by the German Federal Ministry of Education and Research, BMBF, and the Swedish Governmental Agency for Innovation Systems, Vinnova.
