Communications of timing messages over network paths

Abstract

In some examples, a first network device including a first time clock sends, over a first network path, a first timing message of a time synchronization process to synchronize the first time clock and a second time clock that is connected to a second network device. The first network device receives an indication associated with a second timing message of the time synchronization process, where the second timing message is to be sent from the second time clock. Based on receiving the indication, the first network device sends a first join message to a first intermediate network device that is part of the first network path, and a second join message to a second intermediate network device that is part of a second network path different from the first network path. The first network device receives, over the first network path, the second timing message sent by the second time clock, the second timing message communicated over the first network path based on the forwarding information built in the first intermediate network device and the second network device.
