摘要
本文基于分时间片非坚持型CSMA/CD协议,提出了一种新的适合于重负载下评价CSMA/CD总线性能的数学模型.该模型合理地考虑了重载下各种新现象及影响总线性能的诸因素.实验研究结果表明,本文提出的模型较以前的评价模型更接近于实际系统.
Based on a slotted non-persistent CSMA/CD protocol, a mathematical model suitable for assessing the performance of CSMA/CD protocol under heavy load has been developed. This model can deal with various new phenomena and factors influencing the bus performance under heavy load so as to accurately control and handle the main performance indices. Simulation results show that the model developed agrees better with the actual system than currently used models.
