Résumé :

The work presented is part of Deterministic and Dynamic Networks project carried out in collaboration with Nokia Bell Labs France focused on optical networks. The aim is at providing a highly dynamic network that can deliver service determinism, that is, guarantee performance (latency, capacity, reliability, etc.) in an end-to-end fashion. My contributions to this project include the design and implementation of a real-time jitter compensation mechanism allowing to mitigate latency fluctuations within the network by applying per-flow hardware network slicing, per-frame time stamping and latency equalization buffers. In addition to time-wise determinism, a real-time control plane has been proposed and implemented to provide ultra-high dynamics to the network. We managed to reduce the network reconfiguration time from few milliseconds to few tens of microseconds and created new decision-making layers able to react in few nanoseconds. These contributions are highly valuable for time-sensitive applications requiring service guarantees, such as industry 4.0 and machine-to-machine communication.
