| 摘 要： | 文中通过对典型的DTE和DCE数据传输系统中各种延时因素进行分析,给出了一种低开销、开环的软件控制信源速率的方法。通过提高接口速率和合理的估计数据包延时,可以做到延时和丢弃数据包的可控,防止发生信道丢失数据的随机性,可应用于短波、超短波、拨号网络、专线等低速通信传输但同时对延时又有特殊要求的场合。

| Abstract: | The delay of a typical data transmission system consisted by DTE and DCE is resulted by several factors.Through the analysis of these factors,this paper presents a low-cost and open-loop software method to control the speed of the signal source.By increasing the interface speed and reasonably estimating the data package delay,this method can make the delay and the loss of data package controllable and prevent the random loss of data.This method can be applied to those low-speed communication transmission situations which have special requirement of the delay,such as short wave,ultra short wave,dial-up network,a line for special use and so on. |
