| 摘 要： | 试验任务IP网已在高密度试验任务中发挥了积极作用,网络的应用范围也在进一步扩大。针对目前试验IP网中各业务网络计算机时间不统一导致查找、定位网络传输故障点困难的问题,阐述了网络时延的产生,分析其对网络时间同步的影响,重点研究并实现了消除网络时延对时间同步影响的方法。测试表明,该时间同步方法误差小于1ms,满足一般的网络时间同步精度需求。

| Abstract: | IP net has performed an important function in experiment missions, and the application area of net are extending. Aimed at the problem that it is very difficult to look up and orientate faults due to disunion of computers in the IP net,this article introduces the produce of net delay and analyses its influence on the time synchronization, and specially researches on the way of avoiding the influence. Tests indicate that the error of this time synchronization ways is less than 1 ms and satisfies the demand of general net. |
