Abstract: A mechanism is provided for reassigning virtual machines to resources in a computing environment. Monitoring data is collected about virtual machine request history and resource usage in a form of time series for measured indicators. Forecasted time series are computed for the measured indicators over a time window by utilizing time series forecasting. A new assignment is computed by executing a snapshot based assignment algorithm on the forecasted time series. The new assignment is used for reassignment of virtual machines on the resources in the computing environment.

Abstract: Spectrum access for Internet of things (IOT) applications including receiving information about expected use by a primary user of a spectrum band in a radio frequency spectrum. The spectrum band is classified into at least two working modes based on the expected use. The spectrum band is sensed to determine a current access pattern of the primary user. Based on the classifying and the sensing, one of the working modes is selected as a current working mode of the primary user. Transmissions are scheduled on the spectrum band using a current schedule that is responsive to the current working mode of the primary user. If the current working mode of the primary user changes, the sensing, selecting, scheduling, and determining whether the current working mode has changed are re-performed. Otherwise, the transmission scheduling and determining if the current working mode has changed are re-performed.

Abstract: Techniques for configuring a wireless network cloud system comprise the following steps. A density metric is estimated corresponding to at least one given coverage area of a wireless network cloud system. A configuration is determined for one or more network-access components in the given coverage area of the wireless network cloud system in response to the estimated density metric. The determined configuration may then be applied to the one or more network-access components. The density metric may correspond to a user density and/or a traffic density in the given coverage area.

Abstract: Content delivery by a network node is optimized. The network node is communicatively coupled between multiple end user devices and at least one content service provider. A request for a media streaming service available from the content service provider is intercepted from a first requestor device. It is determined if the media streaming service is registered for delivery optimization based on at least one service rule specific to the media streaming service. It is determined if a second requestor device is currently receiving the media streaming service from the content service provider. In response to the media streaming service being received by the second requestor device, delivery optimization of the media streaming service is performed by replicating the media streaming service for delivery to the first requestor device. The replicated media streaming service is sent to the first requestor device.
