Abstract:
A method for controlling delay in a Passive Optical Network (PON) is applicable when a Precision Timing Protocol (PTP) message is transmitted in a downlink direction. The method includes obtaining a buffer duration of the PTP message destined for an Optical Network Unit (ONU), storing the PTP message destined for the ONU, and sending the PTP message to the ONU when a duration for storing the PTP message reaches the buffer duration.
