摘　　要：根据CSMA/CD协议的工作原理,提出了CSMA/CD的固定分配和随机分配两种多业务、多信道的随机多址分配数学模型,通过理论分析和计算,比较了两种模型的吞吐量、信道传输延时特性以及优先级对吞吐量的影响,最后总结出这两种模型的优缺点.According to the principle of CSMA/CD protocol, the paper presents two multiple services and multiple channels mathematic models of CSMA/CD Random Multi-access System based on fix-distribution and random-distribution. Through the theoretical analysis and calculation, the paper compares the performance of throughout and channel transmission delay, and the influence of throughput under different priority models. Finally it lists their advantages and disadvantages.
