METHOD FOR DETECTING A SYNCHRONIZATION FAILURE OF A TRANSPARENT CLOCK AND RELATED PROTECTION SCHEMES

摘要

the invention network 100 of traversing element (104 ₆ ) detecting the synchronization failure 300 in the determining the retention time of the time stamped packets, and a packet network to calibrate 100 a transparent clock used in the (102 ₆ ) relates to a method for the administration, the transparent clock (102 ₆ ) of a plurality of network elements (104 ₅ , 104 ₆ , 104 ₇ ) and their associated transparent clock (102 ₅ , 102 ₆ , 102 ₇ ) master that contains ( 106) and the part of the / slave 108 synchronization path 112, the method includes the following steps: Slave 108 is different paths (110, 112) different from the synchronization path to so as to receive a plurality of time signals transmitted via (110, 112) from the master 106 via the slave 108 to the time stamped packets and transmitting, - a transparent clock failed / failing path, the time signal provided by the 112 different transmission path 110, if different from the time signal provided by the failed / failing synchronization path 112 ( 102 ₆ ) and determining a failure (300) in, - the slave 108 is the failed / failing transparent clock of the synchronization path (112) (102 ₆ ) requesting addition to different synchronization path to determine in a failure (300, 110, 112) a set up of a new synchronization path to the master 106 and / or synchronization management server (114).
