Asymmetric delay compensation

A method for compensating asymmetric link delays for network time estimates in a communication network comprising a first sync node having a plurality of virtual paths (VPs) said plurality of VPs being end-to-end paths connecting said first sync node to one or more second sync nodes, wherein at least two VPs of said plurality of VPs are associated with respective calibration profiles including respective delay correction factors, and data stream characteristics values and/or at least one link path property value, said method comprising:

• monitoring data stream characteristics and/or at least one link path property of at least one VP;
• identifying, among said at least two VPs, a plurality of candidate VPs having respective calibration profiles which match the monitored data stream characteristics and/or at least one link path property;
• selecting, as one or more selected VPs, one or more candidate VPs from among the plurality of candidate VPs by ranking said plurality of candidate VPs;
• and
• calculating one or more time offsets based on the respective delay correction factor included in the respective calibration profile of each selected VP of the one or more selected VPs.
