Abstract�� For the need of the avionics, the survivability of SCI (scalable coherent interface) networks′ structures which may suitable for the avionics was studied. Some distributed switch topologies were selected, such as torodial mesh and wrapped butterfly structures, which are made by the double-node or the skip-a-node SCI node structure and may suitable for SCI networks that will have high survivability. While, comparied with the structures mentioned above for survivability of different structures, two new structures designed were also selected. Both nodes and edges destroyed were considered in this situation. The calculation and analysis of the connection relation were done using the adjacency matrix according the theory of graph. Some types of topologies which has high connection relation were found. The conclusion that changing the direction of ringlets in a same structure can influence the survivability can also be obtained.
