面向单向延迟测量的时钟同步技术研究

为测量网络传输中的单向延迟等性能参数以准确提供和分析网络的性能状况,时钟同步的精度要求已非时钟同步协议(NTP)所能完成。该文对近年来出现的各种针对此问题的时钟同步技术研究和实现展开综述性陈述,并在此基础上提出Altair&Vega(A&V)方法。该方法修正了Moon方法中理论推导的欠妥之处,建立两主机之间同步模型,能提供高精度的相对时钟偏移修正。

Research on Clock Synchronization Technique for One-way Delay Measurement

Network Time Protocol(NTP)cannot meet the accuracy requirement of clock synchronization when measuring the metric parameters,which are valuable for the precise analysis and optimization of the network performance,such as one-way delay of the network transmission.Thus,this dissertation summarizes the latest techniques and research in recent years and compares the existing Synchronization Technique,and on the base of which,it proposed a Altair & Vega meathod.This meatod has corrected the design weakness of Moon meathod and established the clock synchronizaion model of two host,which can provide the precious correction for relative clock offset.
