摘要： The technology includes a method, computer medium, and system for testing audio quality of a transport segment between two core networks. A first virtual test agent (VTA) selects a Mobility Management Engine (MME) corresponding to an eNodeB served by a first core network for routing a second call, through a Serving Gateway (SGW) assigned by the MME for audio communication with a tester terminus. The second call is made from the first VTA to a second VTA at a second core network over a transport-segment-under-test that connects the first and second core networks, So that a tester can evaluate audio quality over the transport-segment-under-test. The first VTA makes a first call to a tester appliance, makes a second call, over the transport-segment-under-test, to the second VTA implementing audio evaluation, by signaling the MME, and bridges the first and second calls by relaying audio during a test of subjective audio quality.

摘要： The technology includes a method, computer medium, and system for remote testing over-the-air (OTA) audio quality using a test platform positioned at core network, the test platform comprising first and second cellular handsets and bridging logic that interconnects, controls, and bridges the first and second cellular handsets. The method includes triggering the bridging logic. The bridging logic initiates a first call over the first cellular handset to a tester, and initiates a second call over the second cellular handset to a destination, wherein the second call is initiated over-the-air. The bridging logic and the first and second cellular handsets are positioned in a location that causes routing by a cellular network of the first call over a segment under test. The bridging logic bridging audio between the first and the second calls, including relaying audio. The tester determines that the second call was established based on the relayed audio.

摘要： A method for determining whether clock skew may exist between a sending node and a remote node during two-way network testing (using protocols such as TWAMP), and a computational method for revising measured latency data to compensate for clock differences.
The method for compensating for clock skew comprises monitoring the network latency between two nodes during a defined time interval. When clock skew is detected, a flag is set, and, after the time interval has completed, clock skew S is estimated using the minimum latency values for the interval. The recorded latency values for the interval are then revised using the calculated clock skew S, and one-way latency results reported.
The improved accuracy can be achieved with only on a few computations after the data have been collected. This a posteriori approach saves on computational resources, which can be at a premium for network testing equipment.-

摘要： Path-loss measurements are determined for a test client device moving along a path in a field test environment in which field Wi-Fi mesh network nodes are distributed. The path-loss measurements are reproduced in a field-to-lab test environment that includes a test client device disposed in an electromagnetically-isolated chamber and field test Wi-Fi mesh network nodes disposed in respective electromagnetically-isolated chambers. The test client device and the field test Wi-Fi mesh network nodes are in wired or wireless communication with each other via signal lines. A programmable attenuator is electrically coupled to each signal line. The attenuation of each programmable attenuator is varied to reproduce the path-loss measurements from the field test environment. Path-loss measurements at the location of each field Wi-Fi mesh network node are also reproduced with the programmable attenuators to reproduce the field Wi-Fi mesh network node configuration.

摘要： The disclosed technology provides resource locators keyed to resource names with failover alternate resource locators keyed to resource positions on user interfaces in a test environment: providing a central repository for resource locators and storing a set of alternative locator expressions for a resource in the central repository. The set includes first resource locators keyed to resource names on UIs and respective second resource locators keyed to resource positions on UIs that can be evaluated when the resource name in the respective first resource locator is invalid. The method invokes a resource location navigator to locate a particular resource using a first resource locator keyed to a resource name on the user interface, automatically invoking the resource location navigator using the second resource locator keyed to the resource position after failure of locating the particular resource using the resource name, and accessing the particular resource using the second resource locator.

摘要： The disclosed technology teaches creating a real time visualization and analysis of Wi-Fi performance and behavior of a DUT in wireless communication with a selected Wi-Fi test device. Also included is performing a radiated test of the DUT using transceiver signals from multiple test antennas impinging on antennas of the DUT, capturing packet details of traffic between the DUT and the selected Wi-Fi test device using a sniffer that is RF coupled to antennas of the selected Wi-Fi test device, and generating a time series summary stream in real time from the packet details captured by the sniffer, including summaries of both performance and behavior metrics. The performance metrics summarize throughput and other measured characteristics of a received signal and the behavior metrics capture transmitter settings that the DUT and test devices choose. Also included is generating scrolling visualizations of selected metrics from the stream as the radiated test proceeds.
