Abstract
A network element includes circuitry configured to receive information related to clock distribution from Precision Time Protocol (PTP) messages from an upstream network element, determine a delta between a network clock from the information and a Primary Reference Time Clock (PRTC), and transmit the delta in PTP messages to downstream network elements. The circuitry can be further configured to receive a configuration of a clock class of a clock at the network element, and transmit the clock class in the PTP messages with the delta. The clock class can be one of A, B, C, and D from G.8273.2 or G.8273.4.
