Before revision:  A class of modified Tanh-Log cumulative distribution function of failure is proposed for aforementioned components in order to achieve a better fit on the real data. In this study, the real experimental data from the lanl2005 database is used to calculate the fitting parameters of the failure cumulative distributions. For the network connectivity, various topologies, such as FatTree, BCube, MDCube, and their modified topologies are considered.
After revision:  To show the capabilities of the proposed approach, various network topologies, such as FatTree, BCube, MDCube, and their modified topologies are considered.
