Abstract: Based on distance vector routing algorithm, this paper improves the update strategy of SpaceWire router, and proposes the Link-State (L-S) route selection algorithm. By analyzing the executive process of L-S route selection algorithm and the principle of Dijkstra algorithm, it completes the design of routing module, and simulates the module by use of a simple network model. Verification result demonstrates that this module can get the information and recalculate new route information of current network automatically, improve the ability of self-adaptive of SpaceWire network and intensify the transmit efficiency as well.
