Abstract: A network device may receive, from a timing source of a network, timing information. The network device may identify a client device to which the timing information is to be provided, wherein the network device provides an interface between the client device and the network. The network device may select a virtual network address to associate with a timing agent of the network device, wherein the virtual network address is within an address range that is reachable by the client device. The network device may provide to the client device, and via a network layer communication, a timing control packet comprising the timing information, wherein the timing control packet identifies the virtual network address as a source network address of the timing control packet, and wherein the timing information is to be used by the client device to update a clock of the client device.

Abstract: A first network device may receive, from a second network device, a clock quality indication that is associated with a clock of the second network device, wherein the clock of the second network device is a reference clock for a network that includes the first network device and the second network device. The first network device may determine, based on a clock signal of the second network device, that a quality metric of the clock does not satisfy a threshold. The first network device may provide, to the second network device, a clock fault notification to cause the second network device to downgrade the clock quality indication transmitted by the second network device. The first network device may select a new reference clock for the first network device based on receiving the downgraded clock quality indication from the second network device.

Abstract: A network device may assign, to a port of a plurality of ports on the network device, a precision timing protocol (PTP) port priority for PTP communications between the network device and another network device. The network device and the other network device may be communicatively connected via a plurality of links in a link aggregation group (LAG). Each port, of the plurality of ports, may be associated with a respective link, of the plurality of links, in the LAG. The network device may generate a link layer discovery protocol (LLDP) frame that includes information identifying the PTP port priority assigned to the port. The network device may transmit the LLDP frame to the other network device to identify, to the other network device, the PTP port priority.

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.

Abstract: In some implementations, a device may receive, via a universal serial bus (USB) interface, configuration information and a supply of power from a network device. The device may receive, via an antenna that is external to the device, a first signal indicating timing information. The device may generate, based on the first signal, a second signal and a third signal, wherein the second signal comprises a one pulse per second signal and the third signal comprises a ten-megahertz signal. The device may provide, to the network device, the second signal and the third signal. The device may receive, via an input port, a clock signal to provide an extended holdover functionality to the network device.
