摘要
研究了在服务调度时,网点处于三种状态,讨论了与通常网络可靠性建模的不同点,采用三态系统来表达网点特定服务事件的概率。建立了多队列服务调度模型,按照M/M/m/m/FCFS服务模式讨论网点服务概率。按照事件发生的条件概率,求得了在小于T时间内,在该调度模式下服务可获性公式,讨论了改进途径。
The nodes has three states when the service is scheduled.it is different from the usual reliability model.The three-state system is used to express the probability of certain event.Multi-queue service scheduling model is established.The probability of network services is discussed according to the mode of the /M/m/m/FCFS.According to Conditions probability of the incident,the obtained service formula in less than T period is give under such scheduling mode.at last the improved ways is discussed.
