报告摘要:The k-dimensional data center network with n-port switches, denoted by Dk,n , has been proposed for data centers as a server centric network structure. The Hamiltonian connectivity and (n+k3)-fault-tolerant Hamiltonicity of Dk,n have been proved by Wang, Erickson, Fan and Jia. In this talk, some properties about Dk,n such as vertex-pancyclicity and the existence of two completely independent spanning trees are given. Furthermore, we consider more faulty edges and prove that Dk,n is conditional (2n+2k9)-edge-fault-tolerant Hamiltonian for any k ≥ 0 and n ≥ 2 except k = 1 and n ≥ 6.
