Welcome to the ORCHESTRA project
An optical network has to be observable before it can become controllable and be subject to optimization, and this is where ORCHESTRA EU project comes in.
ORCHESTRA‘s high observability relies on information provided by the coherent transceivers that are extended, almost for free, to operate as software defined multi-impairment optical performance monitors (soft-OPM). Information from multiple soft-OPMs can be correlated to infer information for unmonitored or un-established paths, effectively supporting alien wavelengths, and localize QoT problems and failures.
The network is viewed as a continuously running process that perceives current conditions, decides, and acts on those conditions. ORCHESTRA‘s advanced cross-layer optimization procedures will be implemented within a new specifically designed library module, called DEPLOY.
A new dynamic and hierarchical control and monitoring (C&M) infrastructure will be then created to interconnect the multiple soft-OPMs and the proposed virtual and real C&M entities running the DEPLOY algorithms, exploiting the reconfigurability capabilities of enhanced tunable transceivers.
At the top of the hierarchical infrastructure, a novel OAM Handler prototype will be implemented, as part of the SDN-based ABNO architecture. The proposed C&M infrastructure will be enriched with active-control functionalities, closing the control loop, and enabling the network to be truly dynamic and self-optimized.
