Abstract
In one example, a network controller manages a network having many network devices. Network devices can receive the timing flow port role assignments from the network controller based on the controller's global view of the network topology. The controller can also calculate timing offsets to be applied to the network devices, based on timestamp information obtained by the network devices via exchanging time synchronization protocol messages, and the controller can update time clocks on all of the network devices within a single window of time, based on a timing offsets calculated in single iteration of calculations.
