Physical Layer Ethernet Clock Synchronization

Abstract

Clock synchronization is a service widely used in distributed networks to coordinate data acquisition and actions. As the requirement to achieve tighter synchronization accuracy arose, protocols like the Precision Time Protocol introduced hardware timestamping, shifting the point where the timestamp is drawn from the application layer towards the physical layer. However, the spread of the synchronization service between hard- and software increased the complexity of the system and still could not solve the issue with asymmetric transmission delays.
