Claim of US Patent No. 9,271,247
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.
