Abstract: Aspects of the subject disclosure may include, for example, a device, including: a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations of: receiving an indication of a priority level of an interworking function used by a boundary clock node; and selecting a best master clock using an algorithm that considers the priority level of the boundary clock node. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a device that includes a processing system including a processor; a clock; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations of: advertising a capability as a precision timing protocol (PTP) master clock through an Internet Protocol (IP) network, wherein the advertising includes an IP address of the device; receiving a unicast signaling mechanism from a PTP client node in the network; and sending clock messages to the PTP client node responsive to accepting the PTP client node. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a device, including: a processing system including a processor; a clock; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations of: advertising via Border Gateway Protocol (BGP) a capability as a precision timing protocol (PTP) master clock through an Internet Protocol (IP)/Multi-Protocol Label Switching (MPLS) network, wherein the advertising includes an IP address of the device; receiving a unicast signaling mechanism from a PTP client node in the network; and sending clock messages to the PTP client node responsive to accepting the PTP client node. Other embodiments are disclosed.
