Description
This study stands as a consolidation to the “SpaceWire Network Management Service Suite Definition and Validation” (SpW-NMS) activity. The SpW-NMS will add a new layer to SpaceWire protocol. This layer will provide a reliable determinism, a timely behaviour, and Quality of Service (QoS) features to the protocols.
The DDCSA study was purposely built to consolidate SpW-NMS by doing an independent assessment of the requirements issued by the SpW-NMS activity; a design and model of the deterministic Spacewire protocol using state machines in a simulated environment provided by an extension of the TASTE tools; the verification of the protocol using also TASTE tools and interfaces with physical SpaceWire hardware; and the construction of use-cases with representative data traffic. The first use-case is a simulation of the SpW network topology of ESA science mission LISA, whereas the second use-case is the data traffic of the COMET-Interceptor probe, whose Platform is similar to the one used in some Sentinel satellites of the Earth Observation program Copernicus.
