Abstract
There is provided a method of clock recovery and a system thereof. The method comprises: by master clock node or by client clock node, generating a first flow of time-stamped packets bearing indication of high priority of delivery and, in parallel, generating a second flow of time-stamped packets bearing indication of lower priority of delivery. By client clock node, processing the packets from the first flow separately from the packets from the second flow to define, separately for each flow, a function informative of changes of packets' delays in the respective flow over time; using the defined functions informative of changes of packets' delays in the first and the second flows over the same time intervals to assess a cause of the packets' delays changes; and applying a clock recovery algorithm in a manner differentiated in accordance with the assessed cause.
