SpaceWire is a protocol developed for space use and specifically for spacecraft. Its numerous advantages enable a wide use in the space industry in particular comparing to the well-known MIL-STD 1553 bus because SpaceWire combines simple, low-cost implementation, with high performance and architectural flexibility. In fact it is a low consumption and high data rates communication link which can even be used for a network. SpaceWire networks are becoming more complex and some problems can occur in different configuration which lead to a need of protocol improvement. ISS-Reshetnev has developed a specific standard based on SpaceWire which brings some mechanisms for providing some Quality of Service (QoS). Using these QoS in a network can bring a high level of determinism on the spacecraft for good equipment and behavior management. This paper aims at exploring and comment on the STP-ISS (Streaming Transport Protocol Information Satellite System) by implementing this additional SpaceWire layer on a NS3 network simulator.
