Abstract
A system includes a first module with a first clock; a second module with a second clock; and an Ethernet network interconnecting the first module and the second module by N Ethernet paths, N≥2; wherein the first module is configured to provide timestamps encapsulated in replicated Ethernet packets to the second module over each of the N Ethernet paths for redundancy. The first module can be configured to obtain timestamps from a first clock with each timestamp having a sequence identifier, replicate each timestamp and its sequence identifier, and encapsulate each replicated timestamp and its sequence identifier in an Ethernet packet and transmit each Ethernet packet over one of the N Ethernet paths. The second module can be configured to receive Ethernet packets over the N Ethernet paths; and utilize a first Ethernet packet with a given sequence identifier for synchronization of the second clock with the first clock.
