This document defines a mechanism for the setup,reoptimization and
recovery of PTP LSP based on the PDV metrics between the 1588 Master
and the 1588 Slave.
When a PTP communication path goes through the third party networks
(e.g. the MPLS networks), the PDV noise caused by the third party
networks will have a significant impact on the synchronization
performance. So, the PDV metrics should be considered in the setup
of PTP LSP.
In addition, when the PDV noise exceeds to a certain degree, it is
necessary to notify the head-end LSR(i.e. the 1588 Master) to switch
to the backup PTP LSP and to reoptimize the primary PTP LSP in order
to improve the PTP reliability.
