Latest Patents

One of Joyner's latest patents is titled "Effective correlation of multiple time-series result sets." This technology relates to a method for storing and time-correlating real-time and queryable test results of a device under test (DUT). The method involves initiating tests on the DUT to collect real-time data from various data streams, which include counters and fact-type values. The collected data, which may have imperfectly synchronized time bases, is gathered from different sources asynchronously. The process specifies a recording time interval for the data collected across multiple databases, ensuring that each piece of recorded data is associated with a particular time interval. At the conclusion of the test, the recorded data is correlated with the test configuration data regarding the test state in the respective time intervals.

Another significant patent is "Resilient coordination, command, and control of widely distributed test agents." This invention utilizes service-based controllers to manage test agents and the performance of multi-agent tests running on a network. In this scenario, a connection-interrupted agent loses its connection to a first controller and subsequently reconnects to a second controller. The second controller accesses a list of active tests that should be running, directing the agent to stop any tests not on the list. The agent then provides a state report on the running tests, allowing for the instantiation and setting of fresh primary and peer coordination finite state machines (FSMs) using the state report. This innovation ensures that the connection-interrupted agent can continue conducting active tests and directing results to the second controller without needing to tear down and restart the tests.
