First experimental demonstration of real-time orchestration in a Multi-head metro network

International audienceWe present for the first time the experimental demonstration of a Real-Time control-plane on the Multi-hEad sub-wavElength swiTching (MEET), Metro architecture. The key control assets are calculated and provided to the edge nodes in a form of grant files. These grant files eliminate the contention possibility at source nodes and destinations, thus they offer a lossless passive optical grooming and multiplexing/demultiplexing at the intermediate nodes. The experimental results validate the control plane structure designed based on a deterministic operating system well scalable for a regional metro network

Is It Worth Adapting Sub-Wavelength Switching Control Plane to Traffic Variations?

International audienceThis paper proposes a novel Metropolitan Area Network (MAN) architecture called Multi-hEad sub-wavElength swiTching (MEET). Compared with the current architectures, MEET proposes to aggregate traffic using passive optical nodes instead of using electrical nodes (switches and routers). Several options regarding a potential control plane are compared in terms of resource allocation efficiency. Two options are relative to the burst assembly process whereas another option is relative to the dynamicity of the resource allocation process. Performance evaluation is carried out using a simulation platform fed by real traffic traces captured on a French operator's metropolitan network. The QoS delivered to three different classes of service has been assessed in terms of latency and jitter. Obtained results show that a control plane that does not adapt to short-term variations of the real traffic may provide QoS levels compatible with an operational MAN
