摘要
5G时代已经到来,需要PTP高精度时间同步技术做支撑。OTN网络必须能够传递PTP时间同步,因此介绍PTP时间同步的技术原理,分析华为OTN传递PTP信息的实现方式,研究现网OTN不具备传递PTP能力的原因及需要改造内容。
The 5G era has arrived and requires PTP high-precision time synchronization technology for support.The OTN network must be able to transfer PTP time synchronization.This paper introduces the technical principles of PTP time synchronization,analyzes the implementation of Huawei OTN to transfer PTP information,and studies the reasons why the existing network OTN does not have the ability to transfer PTP and what needs to be modified.
