Super Structure Fault-Tolerance Assessment of the Generalized Hypercube

Fault-tolerant performance of a network is the prerequisite and guarantee for the normal operation of a network, which is often characterized by connectivity. Let H denote a connected subgraph of G and H-* denote the union of the set of all connected subgraphs of H and the set of the trivial graph. Super H-connectivity (resp. super H-*-connectivity) satisfies the conditions of both super connectivity and H-structure connectivity (resp. H-substructure connectivity). These two kinds of new connectivity provide a new metric to measure the fault-tolerance of the network, that is, the super structure fault-tolerance. The generalized hypercube G(m(r), m(r-1), ..., m(1)) is a universal topology of interconnection networks that contains other commonly used topologies and it has been applied in many data center networks because of its excellent qualities. In this paper, we research the super structure fault-tolerance of G(m(r), m(r-1), ..., m(1)) by studying super H-connectivity ?'(G|H) and super H-*-connectivity ?'(G|H-*) for H ? {K-1,K-M, C-3, C-4, K-4}.
