METHOD FOR PRECISION TIME PROTOCOL SYNCHRONIZATION NETWORK AND APPARATUS
Abstract:
Embodiments relate to the field of communications, and provide a method for a PTP synchronization network and an apparatus, which help to reduce costs of obtaining performance of a Precision Time Protocol synchronization network. The method includes: executing, by a slave clock apparatus, an operation of time synchronization with a first apparatus according to the PTP through a first port; setting a state of a second port of the slave clock apparatus to slave; obtaining information required for determining a time offset between the slave clock apparatus and a second apparatus; determining an offset according to the information; if an absolute value of the offset is greater than a threshold, determining that time synchronization performance of a first link is faulty or time synchronization performance of a second link is faulty; and sending a message to a third apparatus.
