Exemplary methods and apparatuses are provided for a method for correcting for a delay asymmetry of synchronization messages transmitted within a packet-switched network between a master clock and a slave clock, in which the delay asymmetry of the path connecting the master clock to the slave clock is determined and corrected locally within at least one link of said path. One or more signals are transmitted on one or more wavelengths over at least one optical fiber. The one or more signals are received and detected on the one or more wavelengths over the at least one optical fiber. The technique determines an arrival time difference between the received and detected one or more signals, and calculates a delay asymmetry of an adjacent link based on the time difference. |
