Abstract: An access point allocates resource units within a first channel to mitigate interference from an adjacent second channel. The access point obtains a measure of signal strength corresponding to each wireless device attached to an access point, and assigns, for each wireless device, resource units with a first frequency band of the first channel to mitigate interference with a second frequency band of a second channel adjacent to the first channel. An assignment between a set of resource units and a particular wireless device is based on the measure of signal strength corresponding to the particular wireless device. The access point communicates with the wireless devices on the resource units.

Abstract: Methods and systems for distinguishing between radar signals and Wi-Fi signals are provided. When a set of electromagnetic signals are received, various tests are performed on the signals to determine if the signals are associated with radar pulses or if the signals are more likely to be associated with stray WI-Fi signals or other non-radar interference. One such test relies on the relatively small variance of frequencies used by radar pulses when compared to the high variation of Wi-Fi signals. Another test relies on the relatively low peak to average power ratio of signals associated with radar pulses when compared to Wi-Fi signals. The tests described herein are an improvement on existing methods for distinguishing radar signals from Wi-Fi signals and result in less switching of Wi-Fi channels due to erroneously detected radar signals.

Abstract: A system for memory-transfer-based database synchronization in an appliance is provided. During operation, the system can receive, from a database manager on an active unit, a notification indicating that a first memory block has been updated due to an update to a first entry in a first database of the active unit. The system can identify a second memory block that stores a corresponding second entry in a second database of a standby unit. The first and second memory blocks can be in first and second memory segments, respectively, of respective memory devices of active and standby devices. The first and second memory segments can be outside of the accessible memory range of the respective operating systems. The system can then replace the content of the second memory block with the content of the first memory block using a memory-transfer operation, thereby synchronizing the first and second entries.
