A METHOD FOR DETECTING TIMING REFERENCES AFFECTED BY A CHANGE IN PATH DELAY ASYMMETRY BETWEEN NODES IN A COMMUNICATIONS NETWORK

摘要

method for detecting a master node and each of the slave clock to a plurality of slave timing references affected by the change in the path delay asymmetry in a communication network comprising nodes with each having a master clock It is provided. The method of the first slave received first by the node comprising: first timing reference is determined to represent the time correction of the large slave clock than the time correction threshold, one or more other slave nodes is greater than the time correction threshold, their slave clock a first step of determining whether it has received a timing reference indicating the time correction, and one or more other slave nodes based on the determination of whether or not it has received a timing reference that represents a significant, time correction of their slave clock than the time correction threshold 1 reference timing is affected by the change in the path delay asymmetry it includes determining whether. Apparatus, and computer program for detecting a reference timing affected by changes in the path delay asymmetry in the communication network is also provided. ;
