Proposal of Transmission Delay Measurement Method during PTP Profile Conversion

In fields such as mobile communications, video, and finance, the Precision Time Protocol (PTP) is an effective method for achieving highly accurate time synchronization. However, PTP profiles differ depending on field in which used, synchronization not possible between different profiles. Therefore, when telecommunication carriers distribute to each field, networks are required profile, resulting high equipment costs. this paper, we propose a convert profile of upper match lower equipment. Among items that need be converted profiles, conversion transmission delay measurement examined, actual verification shows accuracy meets generally standard (1000 ns or less).
