Claim Text:
1. A method of characterizing a synchronization behavior of a slave device by dropping sync packets, the method comprising: transmitting a sequence of sync packets from a grandmaster device to a slave device, wherein the sync packets are received at an intermediate device and forwarded to the slave device; monitoring a synchronization output of the slave device that is usable to determine whether the slave device is synchronized with the grandmaster device; at the intermediate device, dropping one or more of the sync packets, wherein dropping one or more of the sync packets includes dropping one or more of the sync packets in a variety of repetitive patterns such that each of the repetitive patterns is transmitted for a respective period of time; while dropping one or more of the sync packets, determining whether the slave device is synchronized with the grandmaster device; and storing an indication that characterizes the synchronization behavior of the slave device with respect to each variety of the repetitive patterns.
