Abstract In order to satisfy the requirement of aerocraft’s multi- transmission for further development, this paper leads to a resolution about on-board SpaceWire routing technology. Based on the network level analysis of SpaceWire standard, it built the architecture of router with wormhole routing theory and non-blocking switch mechanism. A simulation model of router had been set to verify the design, and braking-problem from wormhole routing-blocking had been solved with BWR (Buffered Wormhole Routing), it reduces 70% average packet-losing ratio on full load communication.
