Aiming at the PTN equipment deployed by a telecommunication operator

this paper combines the current situation of PTN

builds time distribution points at different levels

and determines the location of time distribution points. According to pure PTN bearing

PTN over OTN

PTN relay scenarios

this paper proposes the deployment scheme of IEEE 1588 V2 time synchronization network to ensure the stable operation of communication network equipment

and for different application fields. Scenery analysis and comparison of advantages and disadvantages.
