分组传送体制下的时钟特性

The Timing and Synchronization Characteristic in Packet Transport Systems

在OTN与PTN成为城域传送网主流技术的今天,网络定时分配和业务时钟恢复出现许多新的特性,本文围绕这两种技术体制的特点以及可能的组网状况,对传送网的时钟特性进行分析和阐述。

As OTN and PTN become the primary transport technique nowadays,there are many new features for the system clock recover and timing designate.This paper discusses the characteristics of these two transport hierarchies and the likely application structure,as well as the timing and synchronization characteristic under these hierarchies.
