What is the PTP Grandmaster Clock?
TP is a time synchronization protocol defined in IEEE 1588 version 2 (ITU-T G.8275.1) for devices across a network. Using PTP, you can synchronize distributed clocks with nanoseconds accuracy. The clocks in the PTP-enabled devices follow a master-slave hierarchy. The slaves are synchronized to their masters. The top-level master is called the grandmaster. The grandmaster clock is synchronized with a Global Positioning System (GPS). In a PTP-enabled network, synchronization between master and slave clocks occurs through a series of message exchanges. The master first sends a synchronization message to the slave. In response, the slave sends a delay request to the master, which then replies with a delay response. This process measures the network delay and ensures that the slave clock is accurately synchronized with the master clock. This synchronization method is known as one-step synchronization.
