Methods and arrangements for determining a network connectivity model. Meters are interfaced with, and periodic synchronous power-related measurements are collected from different meters. Measurement messages are sent to a predetermined location for being consolidated and processed, and a network connectivity model is thereupon determined.

Methods, apparatuses, and computer program products for controlling communication between whitespace devices are provided. Embodiments include identifying, by a base-station array controller, a user whitespace device within a coverage area of a base-station array, wherein the base-station array includes a plurality of base-station whitespace devices of varying power consumption profiles; identifying for each base-station whitespace device, by the base-station array controller, transmission channels available to the base-station whitespace device; selecting from the plurality of base-station whitespace devices, by the base-station array controller, a base-station whitespace device based on the power consumption profiles and the identified available transmission channels corresponding to the plurality of base-station whitespace devices; and instructing, by the base-station array controller, the selected base-station whitespace device to communicate with the identified user whitespace device on one of the identified available transmission channels.

Methods and arrangements for facilitating virtual machine migration across data centers. A virtual machine is designated for migration from a first data center to a second data center, the virtual machine including a real identifier. A pseudo identifier is assigned to the virtual machine, and the pseudo identifier is mapped to the real identifier at a controller of the first data center. The real identifier is replaced in a data packet with the pseudo identifier for a routing task. Communication is maintained between the controller of the first data center and a controller of the second data center, and the controllers are synchronized to update a correct location of the virtual machine. The virtual machine is migrated from the first data center to the second data center.

Methods and arrangements for optimizing streaming of a group of videos. Throughput of video streams through a common link to at least two different destinations is permitted. An effective flow rate for each video stream is ascertained, and a playout lead for each video stream is estimated. The playout leads are equalized via dynamically changing the effective flow rates of the video streams.
