ABSTRACT:
A method and system for adjusting a clock signal in a network element of a data network adjusts the clock signal based on difference values formed by received synchronizing messages. Each difference value is a difference of a reception and transmission values of a received synchronizing message. The reception value depends on a cumulated number of periods of the clock signal at a moment of arrival of the synchronizing message. The transmission value depends on a position of the synchronizing message in a chronological transmission order of synchronizing messages. When adjusting, an adjusting effect of the difference values belonging to a lower part of a margin of fluctuation of the difference values is weighted more heavily than that of an upper part. Thus, for clock signal adjustment, that share of information represented by the received synchronizing messages that has the least interference is used, irrespective of the data network load.
