Abstract
The invention relates to time synchronization between network testing elements in distributed network monitoring and testing systems, and provides a method for synchronizing packet timestamps generated by a network probe with a free running clock to a master clock connected at a different location of the network. In one implementation, the probe eavesdrops on a PTP message exchange between the master and a remote slave device, recording message reception times according to it free running clock and transmitting relevant timing information to a rest server for determining the probe clock offset and updating the probe packet timestamps.
