Abstract:
A master node is configured to receive, from a slave node, a request to perform a modified two-step synchronization (sync) operation in a manner that precludes transmitting a follow-up packet; generate a sync packet in a manner that includes information associated with a previous time that a prior sync packet was transmitted to the slave node; transmit the sync packet to the slave node; receive, from the slave node, a delay request packet; transmit, to the slave node, a delay response packet, where the delay response packet stores information associated with another time at which the delay request packet was received, and where transmitting the delay response packet enables the slave node to calibrate a clock, hosted by the slave node, to a master clock, hosted by the master node, based on the previous time and the other time.
