Apparatus, method and non-transitory computer readable medium for bandwidth estimation for a network using traffic shaping detection are provided, including selecting periodically sampled packets from the network, bandwidth samples each having a delay jitter greater than a jitter threshold, the delay jitter of a packet determined as the difference between a delay for the packet in the network and a minimum delay for all packets sampled within a delay statistics window for the packet; updating a probability distribution of sampled bandwidth based on the selected bandwidth samples; determining whether traffic shaping is occurring in the network based on a density of the updated probability distribution of sampled bandwidth; and based on a determination that traffic shaping is occurring in the network, adjusting an upper limit of estimated bandwidth for the network based on an estimated traffic shaping rate, the estimated traffic shaping rate determined based on the updated probability distribution.

Traffic shaping detection and bandwidth estimation for a network

An automatic SDK testing case generation system includes a computer software application for automatically generating optimized test cases. The automatic SDK testing case generation system categorizes candidate APIs presented by an SDK to be tested. The categories conform to an API call category sequence. The system iterates through API calling paths, which conform to the API call category sequence, to generate optimized subsets of test cases. The combination of the optimized subsets of test cases forms the final set of test cases for being used to test the SDK.
