Abstract
A network device may receive a timing control packet from a first client device. The network device may determine that the network device is in a synchronized state relative to a network grandmaster clock. The network device may modify a first field of a header of the timing control packet to indicate that the network device is in a synchronized state. The network device may modify a second field of the header of the timing control packet to indicate a time at which the network device received the timing control packet from the first client device. The network device may forward, via the network, the timing control packet toward a second client device.
