Latest Patents

Hong-guang Shi 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, achieving stable time synchronization, and assessing the timing offset or path delay of the slave clock DUT before introducing disturbances. By sending abnormal messages 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, thereby verifying the compliance of the slave clock DUT with the IEEE1588 protocol.
