Abstract: Techniques are disclosed to implement an adaptive testing service (ATS) capable of automatically generating test cases for a network service to adapt test coverage to observed behaviors of the network service. In embodiments, the ATS uses telemetry data from a production version of the network service to identify classes of testable behaviors. Test cases are generated for the behaviors and assigned weights based on frequency or recency metrics of the behaviors. The test cases are stored in a test case repository, and may be used to monitor the production version of the network service or verify code changes to a development version of the network service. The test case weights may be used to select which test cases to run or determine whether code changes should be accepted or rejected. The test cases are evolved over time to adapt to behavior changes in the network service.

Abstract: Because of the line-of-sight character of optical wireless communication and a limited field-of-view of optical receivers, the coverage of an access point (120) and the overlapping coverage area of adjacent access points (120) in an optical system are smaller as compared to a RF system. It turns more challenging to support an end point (110) to roam securely in an optical multi-cell wireless communication network (100). To address that problem, a subsystem is disclosed to select for the end point (110) a candidate access point out of the plurality of access points (120) in view of one or more neighbor relationships, and to inform the end point (110) about the candidate access point to trigger the end point (110) to start a procedure for pre-establishing a new pairwise transient key between the end point (110) and the candidate access point (120) for a secure handover.

Abstract: For a non-volatile memory system with a multi-plane memory die having a large block size, to be able to more readily accommodate zone-based host data using zones that are of a smaller size that the block size on the memory, the memory system assigns data from different zones to different subsets of the planes of a common memory die. The memory system is configured to accumulate the data from the different zones into different write queues and then assemble the data from the different write zones into pages or partial pages of data that can be simultaneously programmed into memory cells connected to different word lines that are in different sub-blocks of different blocks in the corresponding assigned planes of the die.
