Abstract: Network presence of a computing device in a cloud computing network is maintained while power consumption of the computing device is reduced. When the computing device is determined to enter an idle state, at least some of the operations of the computing device running in a virtual machine environment are migrated to a server within the cloud computing network while maintaining connectivity of the computing device to the cloud computing network. When the computing device is determined to be in the idle state, the computing device is put into a sleep mode to reduce power consumption of the computing device. When the computing device is determined to be in an active state, the computing device is woken, and the migrated operations are returned from the server to the computing device. This reduces power consumption of the computing device while maintaining the network presence of the computing device in the cloud computing network.

Abstract: A method and apparatus for providing a resource allocation policy in a network are disclosed. For example, the method constructs a queuing model for each application. The method defines a utility function for each application and for each transaction type of each application, and defines an overall utility in a system. The method performs an optimization to identify an optimal configuration that maximizes the overall utility for a given workload, and determines one or more adaptation policies for configuring the system in accordance with the optimal configuration.

Abstract: Certain exemplary embodiments comprise method that can comprise receiving information indicative of a fault from a monitor associated a network. The method can comprise, responsive to the information indicative of the fault, automatically determining a probability of a fault hypothesis. The method can comprise, responsive to a determination of the fault hypothesis, automatically initiating a recovery action to correct the fault.
