Abstract: For a virtual distributed network environment employing physical forwarding elements that includes both software forwarding elements and third party devices serving as hardware forwarding elements, a scalable method for synchronizing configuration data of logical forwarding elements that are distributed across the various physical forwarding elements is provided. The method generates and updates the configuration data at a set of central controllers and then distributes the configuration data to the physical forwarding elements. The method delivers the updated configuration data to some of the physical forwarding elements by (i) determining a delta/differential between the updated configuration data held at the central controller and the obsolete configuration data held at those physical forwarding elements and (ii) delivering the determined differential configuration data to the physical forwarding elements.

Abstract: Electronic devices may be tested using a test station with a test fixture. The test fixture may include a first holding structure in which a device under test may be placed and a second holding structure for supporting test probes. The second holding structure may be mated with a test probe alignment structure during test station setup operations. The test probe alignment structure may include registration features configured to set the relative position of the first and second holding structures to a known configuration and may include test probe alignment features that can be used to correctly position the placement of the test probes. If at least one of the test probes is not sufficiently aligned to its corresponding alignment feature, the test probe alignment structures will not be able to engage properly with the second holding structure, and the position of the problematic test probe may be adjusted accordingly.

Abstract: A method of maximum output power configuration with UE preference in carrier aggregation is provided. A UE configures multiple component carriers (CCs) with carrier aggregation for communicating with a serving base station in a mobile communication network. The UE determines channel condition of multiple serving cells over the corresponding multiple CCs. The UE then determines maximum output power for each CC based at least in part on the corresponding channel condition of each CC. Finally, the UE transmits power headroom report (PHR) for each CC to the serving base station, wherein the PHR is calculated based on the determined maximum output power. As a result, the reported PH information is channel condition dependent, which can be used by eNB for facilitating better transmission scheduling.
