单令牌环网通信时间的极值问题

The Extreme Value Problem of the Time Spent in Single Token Ring Network

本文讨论了单令牌环网的流通量及环网通信时间的极值问题，根据环网通信通道上消息的平均通信时间是消息平均等待时间，消息平均传输时间和消息平均广播延迟时间的总和，在欧氏空间中对流通向量进行分析，得到了环网通道全部通信时间的变化规律及最佳流通量。

In this paper,the throughput and the extreme value of the time spent in single token ring network are discussed.The fact is that the average time that a message spends in the communication channel is the total sum of the mean message waiting time,themean message transmission time and the mean propagation delay time.By analyzing the throughput in Euclidean space,the optimal throughput and the changing law of the total spending time are obtained.
