Abstract

Operation of a synchronization network that includes a number of nodes and reference clock distribution logic includes, at each of the nodes, storing a table that represents a most recent status of the synchronization network. Reference clocks are then distributed to each node in the synchronization network. If a change in synchronization status occurs at a node in the synchronization network, this change is detected. The table at the node is updated to represent an updated status of the synchronization network. Then, a synchronization network management protocol is used to distribute the updated status to other nodes in the synchronization network. Other nodes may change their status in response to receipt of the updated information, and information about these additional updates are distributed throughout the synchronization network in a similar manner, thereby facilitating control of the synchronization network.
