In a network having at least one slave node including a slave clock, a method of adjusting the slave clock relative to a master clock of a master node includes, at the slave node, correcting a time of day of the slave clock using (a) a slave pulse signal having a known slave pulse rate, (b) a time-of-day counter of the slave node, and (c) a master pulse signal, based on values of the slave clock at nearest corresponding edges of the slave pulse signal and the master pulse signal, and correcting a frequency of the slave clock using the slave pulse signal, a clock signal of the slave node, and the master pulse signal, based on values of the slave clock at nearest corresponding edges of the master pulse signal. No other clock signal from outside the slave node is used for the corrections.

Time-of-day correction for network clock protocol

Systems and methods for packet re-transmission via a bi-directional wired interface between two devices are provided. A transmitter of a first device transmits one or more first transmit data packets to a second device over the bi-directional wired interface. Concurrently with the transmission of the one or more first transmit data packets, the first device receives, over the bi-directional wired interface, one or more second received data packets from the second device. A packet integrity monitor of the first device monitors whether one or more received data packets of the second received data packets is corrupted at the physical layer of the first device. In response to detecting that one or more received data packets of the second received data packets is corrupted, the first device re-transmits one or more transmit data packets of the first transmit data packets that was previously transmitted over the bi-directional wired interface.
