Abstract
The invention relates to time synchronization between network testing elements in distributed network monitoring and testing systems, and provides a condensed PTP process wherein the number of timing messages exchanged between master and slave in one iteration of the time synchronization process is reduced. Furthermore, timing messages are encrypted to provide for a more secure synchronization process. One aspect of the method provides for an automatic detection and adaptive handling of protocol stacks of received timing packets.
