集散系统实时性与存取控制方式的关系

The Relationship Between Real-Time Characters& Access In The distributing system

为了使得集散系统具有优良的“实时性”,本文提出了下列措施作为约束条件:每一站点每次通信时间必须予以限定;在一个时间周期内,每一站点应至少有一次机会获得通信权;建立通信优先级;增加有效数据传输率;减少不必要的通信量。

In order to get excellent real-time ability of a collecting and distributing system, the following methods are used: The Communication time of each station per time must be limited; during certain time-cycle each station all have the chance to get the rule of communication; set up the communication priority; incrense the effective data transmission and decrense the unnecessary communication amount.
