(n,k)-星星图Sn,k继承了星星图的优点,同时又提供了各种网络尺寸,是一种很有前途的并行处理系统互连网络拓扑结构。在这项研究中,我们提出了一个容错路由算法,建立一个无故障的路径之间的任何一对非故障节点在Sn,k故障节点使用有限的全球信息称为安全向量。此外,我们进行了计算机实验,以验证其有效性。
An (n, k)-star graph Sn, k is a promising topology for interconnection networks of parallel processing systems because it inherits the merits of a star graph while providing various network sizes. In this study, we propose a fault-tolerant routing algorithm that establishes a fault-free path between any pair of non-faulty nodes in an Sn, k with faulty nodes by using limited global information called safety vectors. In addition, we carried out a computer experiment to verify its effectiveness.
