摘　　要：文中利用信道接入技术对通信端到端的传输时延进行计算,首先将时延分为传输设备传输时延、数据帧长度时延、线路时延,然后计算通信端到端的传输时延,以获得整个通信信号时序序列的计算方法。利用信道接入技术,采用计算模型,计算时延序列中单组信号的出现概率,在此基础上计算出通信端到端的传输时延。最后开展仿真实验,实验结果表明信道接入能够减少计算误差。This paper uses channel access technology to calculate the end-to-end transmission delay of communication.First,the delay is divided into transmission device transmission delay,data frame length delay,and line delay.Then,the end-to-end transmission delay of communication is calculated to obtain the calculation method of the whole communication signal sequence.Using the channel access technology and the calculation model,the probability of occurrence of a single group of signals in the delay sequence can he calculated.On this basis,the end-to-end transmission delay of communication can be calculated.Finally,the simulation experiment is carried out.According to the experimental results,it can be determined that the channel access can reduce the calculation error.
