Zusammenfassung |

[EN] The method for managing an accurate distribution of time in a packet network, the packet network comprising a peer-to-peer transparent clock hardware support in at least one network elements (NE), the transparent clock hardware support enabling a local delay measurement mechanism between two adjacent transparent clocks, a Master (106) /Slave (108) end-to-end synchronization path (112) comprising a first set of network elements (104 1 , 104 2 , 104 3 ) and their associated transparent clocks (102 1 , 102 2 , 102 3 ), the Master (106) and slave (108) exchanging unidirectional time stamped packets through the first set of network elements, wherein the method comprises :
— generating a first indicator in at least a specific field of a first time stamped packet by a first element (NE1) when a failure occurs which disables the local delay measurement mechanism between the first element and a second element of the first set ;
— starting requesting a two-way signalling mode comprising generating at least a second time stamped packet in order to measure a second delay corresponding to an end-to-end transmission delay (TD2) of the second time stamp packet from the slave (108) to the Master (106). |
