    Abstract: Likely disconnections or system-level-impact producing slowdown in a flow parameter in a network can be identified by annotating a graph representing the network with a weight to edges of a graph representing the network. The weight can be linearly or non-linearly proportional to the inverse of the severity of the impact, and/or linearly or non-linearly proportional to the inverse of the likelihood of disconnection. Minimal cut sets needed to generate a disconnection in the network are identified from the annotated network based on the weights on the edges. Subsets of each minimal cut set are generated and evaluated during a simulation. The subsets can correspond to almost isolated scenarios for the network. The scope of the simulations can be reduced by selecting the minimal cut sets employing the weight.

    Abstract: A method for provisioning IT resources includes receiving a signal from an e-book reading device indicating that a user of the e-book reading device is approaching a practical procedure section within an e-book being read by the user on the e-book reading device. The practical procedure section includes an exercise to be performed by the user pertaining to the subject matter of the e-book. What IT resources are needed for the user to perform the exercise are determined. The needed IT resources are provisioned such that the IT resources that the needed IT resources are available when the user is ready to perform the exercise.
