The invention relates to a method for synchronizing multipoint measurements in a data transmission network (100) having observation apparatuses (11, 12, 13) which perform measurements, wherein the observation apparatuses (11, 12, 13) have associated pulse-coupled oscillator apparatuses (21, 22, 23) which each have a charging function v(t) which increases between v(t=0)=0 and v (t=tMax) = vMax, and each of the pulse-coupled oscillator apparatuses (21, 22, 23), upon reaching the threshold value vMax, automatically sends a signal (30) for other pulse-coupled oscillator apparatuses (21, 22, 23) and is then set to v=0, wherein the time interval 0 to tMax determines the frequencies of the oscillator apparatuses (21, 22, 23), the pulse-coupled oscillator apparatuses (21, 22, 23) which receive the signal (30) involve the charging function v(t) being raised by the absolute value s, with the result that all the oscillator apparatuses (21, 22, 23) which are coupled to one another by signals (30), and hence also the coupled observation apparatuses (11, 12, 13), synchronously perform measurements on the data packets in the data transmission network on the basis of the self-synchronizing properties of the pulse-coupled oscillator apparatuses (21, 22, 23), with a synchronized selection probability ps of the observation apparatuses (11, 12, 13) being formed for the data traffic from the functional relationship between the charging function v(t) and the selection probability such that the selection probability ps negatively correlates to the frequency of the oscillator apparatus (21, 22, 23). The invention also relates to an apparatus. |
