摘要
AbstractIn order to satisfy the rapidly increasing demand for data volume, large data center networks (DCNs) have been proposed. In 2019, Zhang et al. proposed a new highly scalable DCN architecture named HSDC, which can achieve greater incremental scalability. In this paper, we give the definition of the logical graph of HSDC, named \(H_n\), which can be treated as a compound graph of hypercube and complete graph of the same dimension. First, we prove that the connectivity and tightly super connectivity of \(H_n\) are both n. Then, we give an O(n) routing algorithm to find a shortest path between any two distinct nodes in \(H_n\), and prove the correctness of this algorithm. In fact, we also prove that the distance constructed by this algorithm is no more than \(2d+1\) if \(d
