摘要

文章介绍了E1 over基于以太网的无源光网络（EPON）的关键技术中时钟同步的实现方法

通过对自适应法的研究和改进

优化了时钟输出抖动的指标

有效地保障了EPON系统的服务质量（QoS）指标。相对于时间标签法

自适应法在分组网络中进行时钟同步方面具有更广泛的适用空间。

Abstract

The present study mainly focuses on the realization of clock synchronization

a key technology of E1 over EPON.With an in-depth study of the adaptive method

this article has expounded on an improved way

in which the markers of clock output jitter have been optimized and the QoS of the EPON system effectively ensured.Compared with the time stamp method

the proposed adaptive method for clock synchronization is far more extensively applicable in packet networks.
