SCI网络拓扑结构的可生存性

从航空电子系统的需求出发,研究了适于航电系统的SCI(Scalable Coherent Interface)网络拓扑结构的可生存性.选择了由双节点或skip-a-node结构形式构成的网格形、蝶形等适于SCI网络的拓扑形式并构造了二种网络拓扑结构以便于不同结构的可生存性比较.同时考虑边及节点损坏的情况,利用图的邻接矩阵对网络连通关系进行了计算和分析,找到并印证了具有高可生存性的拓扑形式,同时发现相同结构下小环方向的改变对可生存性也有影响. 

Survivability of SCI network topologys

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.
