SpaceWire has become a de facto standard for payload systems (including for Command Control) and its Real-Time derivatives are now being considered for avionics. The capability provided by SpaceWire to develop data handling systems based on high-speed networks allows much greater performance but implies implementing communication bus management techniques specific to SpaceWire. As network management is not part of the basic SpaceWire protocol ECSS-E-ST-50-12C (Rev.1), it must be provided to industry in the form of an additional standard. The different elements of the SpW network management have been developed separately so far. The tasks related to this activity are: 1. Merging and consolidation of requirements for a Network Management Service Suite (N-MaSS) covering SpaceWire network discovery, configuration, and FDIR 2. Detailed specification of N-MaSS in the form of a draft ECSS standard 3. Prototyping ofthe specified N-MaSS 4. Verification (test) the prototyped SpW network management services 5. Validation of the SpW Network Management Service Suite through demonstration of its capabilities in one or more scenario(s) representative of spacecraft data handling (the BepiColombo/Solar Orbiter SpaceWire network and the MTG/MetOp-SG SpaceWire network should be considered as baselines, which leadsto quite a number of SpaceWire nodes and switches) The main deliverables are a SpW N-MaSS specification that shall be in the form of a draft ECSS standard, ready for improvement by the International SpW Working Group before potential adoption by ECSS, a prototypeimplementation of N-MaSS in a number of master and slave nodes, as well as switches and a demonstrator (HW SW) of the N-MaSS capabilities. Procurement Policy: C(2) = A relevant participation (in terms of quality and quantity) of non-primes (incl. SMEs) is required.
