Abstract: Clock synchronization in a network includes receiving, by a slave network device from a master network device via at least a intervening network device, a timing packet comprising a transmission timestamp and a residence time. The transmission timestamp is based on a master clock of the master network device. The residence time corresponds to a delay of the timing packet traversing the intervening device. Clock synchronization in a network further includes generating, by the slave network device in response to receiving the timing packet, a receiving timestamp based on a slave clock of the slave network device, and generating, based at least on the transmission timestamp, the residence time, and the receiving timestamp, a time difference between the master clock and the slave clock. Clock synchronization in a network further includes synchronizing, based at least on the time difference, the master clock and the slave clock.
