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.
Claims20
A device, comprising:
- a processing system including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
- 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 interworking function.
A device, comprising:
- 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, the operations comprising:
- receiving first timing information from a time source;
- receiving second timing information via partial timing support over an Internet Protocol network;
- and
- providing an indication of a priority level of an interworking function in an announce packet of precision timing protocol to a downstream node.
A non-transitory, machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:
- receiving first timing information from a time source;
- receiving second timing information via partial timing support over a multiprotocol label switching network;
- and
- providing an indication of a priority level of an interworking function in an announce packet of precision timing protocol to a downstream node.
