非PTP设备应用于PTP系统中对同步精度的影响
|
摘要
随着网络通信技术的发展,PTP已经在众多系统领域得到使用。根据不同用户的同步精度需求和工程成本要求,对于PTP网络建设设备组成产生了不同的需求。必要时候PTP网络在能够达到同步精度的要求下可以添加不支持PTP的设备。文章将不支持PTP的设备接入PTP同步系统进行试验,分析了不同种类的非PTP设备对于PTP网络时钟同步精度的影响。根据实验结果结合时钟同步理论,对PTP同步系统设备配置进行合理建议。文章的内容可以作为需要节约成本的同步网络建设及类似工程的参考依据。
With the development of network communications technology,PTP is widely used in many systems.Based on user requirements of synchronization precision and engineering cost,the different device composition is required for PTP network construction in different projects If necessary,the non- PTP device can be used in PTP network when the synchronization predsion can meet the requirement of user.This paper analyzes the effect of different non- PTP devices on PTP network clock synchronization precision.Based on experimental results and clock synchronization principle,this paper puts forward some suggestions for PTP system configuration.The content of this paper can be used as reference in projects such as cost saving PTP system construction.
