IEEE 1588协议应用的网络影响分析

IEEE 1588协议作为新一代时间同步技术，采用IP网络作为时钟信息传输路径，通过2个时钟之间延时测量，计算并修正时间偏差，因而协议应用与网络环境密切相关、从介绍协议基本原理出发，分析了网络影响修正时间偏差的主要机理。，之后重点分析了网络拓扑对时间同步链路时延的一致性影响，网络设备对时间同步链路时延计算；住确性的影响程度。以及网络运行情况对时间同步链路时延稳定性的影响。

Analysis on Influence of IEEE1588 Protocol Applied in Network

As a new generation of time synchronization technology, IEEE1588 protocol uses the IP network as the time information wammmion： path, calculates and corrects the time deviation by means of delay measurement between two clocks. As a result, protocol application is closely related to the network environment. This Paper firstly introduces the basic principle of protocol and analyzes the network on correction of time deviation .And then paper emphatically the influence of network topology on the consistency of time synchronous delay, the influence degree of network equipment on the calculation accuracy of time synchronous link delay and the influence of network operation condition on the stability of time synchronous link delay.
