Abstract
A network includes a first plurality of nodes operating in a first clock domain based on a first clock source, a second plurality of nodes operating in a second clock domain based on a second clock source, and synchronization circuitry accessible to both of the clock domains without requiring network traffic between the clock domains. The synchronization circuitry is configured to periodically calculate a drift rate between the time of day in the respective clock domains. Each node in one of the clock domains is configured to, when sending a message to a node in the other of the clock domains, calculate a time of day in the other of the clock domains based on an actual time of day in the one of the clock domains and the drift rate, and to include, in the message to the node in the other clock domain, the calculated time of day.
