Latest Patents

Tuo-fu Zheng holds a patent for an IEEE1588 protocol negative testing method. This invention involves a series of steps that establish a real-time closed-loop feedback mechanism between an IEEE1588 tester and a slave clock device under test (DUT). The method includes taking the tester as a master clock to achieve stable time synchronization with the slave clock DUT. It also involves obtaining the timing offset or path delay of the slave clock DUT before introducing disturbances. By assembling an abnormal message and sending it to the slave clock DUT, the method calculates the timing offset or path delay increment after the disturbance. The test determines if there is a sudden change in the timing offset or path delay, which indicates whether the test passes or fails. This innovative testing method effectively utilizes the correction field in the IEEE1588 message to enhance the response of the slave clock DUT to abnormal message stimuli.
