Abstract
A packet network includes a peer-to-peer transparent clock hardware support, a peer-to-peer transparent clock being at least used in order to measure and correct delays of link or path adjacent to network elements and NE residence time, and a Master/Slave end-to-end synchronization path including a first set of network elements A time stamped packet including at least a correction field indicating the cumulated transmission delay of the said packet along the synchronization path. A method includes a detecting a failure event; storing by the first element a measured past path delay of at least one previously transmitted time stamped packet received by the first element; and a function of the incoming current value of the received correction field, the first network element residence time, and a first value depending of a measured past path delay value. A first indicator is generated when detecting a failure.
