PTPprecision time protocol Clocks timing fault recovery method and apparatus in precision time protocol system

摘要

A time synchronization failure recovery method and apparatus in a precision time protocol (PTP) system are disclosed. The method of recovering the time synchronization failure of the slave node in the PTP (Precision Time Protocol) is a method of recovering the time synchronization failure of the slave node by receiving a time synchronization signal to the remaining topsoil in case of a failure during time synchronization to a specific port, Time synchronization can be performed through a signal. Accordingly, the present invention has an advantage in that time synchronization of the network can be stably maintained by detecting and recovering a failure in a short period of time.
