An example method includes creating, by a computing system and in response to user input, one or more virtual master devices and a plurality of virtual leaf devices in a virtual network system; selecting, by the computing system, data from one or more of real-time clock offset data, prerecorded clock offset data, or synthetically generated clock offset data; executing, by the computing system, a time synchronization simulation by applying a predefined clock offset generation algorithm to the selected data; and outputting, by the computing system, data indicative of results of the time synchronization simulation.

Simulating time synchronization

The disclosure describes methods and systems for performing time synchronization in a heterogeneous system. In one example, a method includes, for each secondary device of one or more secondary devices in a network, determining, by a computing system, one or more time synchronization characteristics for the respective secondary device; and generating, by the computing system and based on at least the respective one or more time synchronization characteristics for each respective secondary device of the one or more secondary devices in the network, a time synchronization report for the network, wherein the one or more time synchronization characteristics include health data for the one or more secondary device.

Clock synchronization in a heterogeneous system

The disclosure describes methods and systems for performing time synchronization in a heterogeneous system. In one example, a method includes evaluating, by a computing system, one or more network conditions of a network to determine whether to perform a time synchronization process with a secondary device in the network, wherein the one or more network conditions include a health score for the secondary device, and, in response to determining, based on the evaluation of the one or more network conditions, to perform the time synchronization process: determining based at least in part on a time indication for a clock on a master device and a time indication for a clock on the secondary device, a time synchronization offset for the secondary device; and sending the time synchronization offset for the secondary device to the secondary device in a data packet.
