摘要
There is provided a method for sensing a timing reference that is affected by a change in path delay asymmetry in a communication network comprising a master node having a master clock and a plurality of slave nodes each having its own slave clock. The method includes determining that the first timing reference received by the first slave node represents a time calibration to a slave clock greater than the time calibration threshold, determining that the one or more other slave nodes have a time calibration threshold greater than the time calibration threshold, Determining whether the one or more other slave nodes have received a timing reference indicating a time correction to their slave clock that is greater than a time calibration threshold, Determining whether the timing reference is affected by a change in path delay asymmetry. An apparatus and a computer program for detecting a timing reference that is affected by a change in path delay asymmetry in a communication network are also provided.
