Each block in the diagram can be further decomposed into its constituent submachines. At the most detailed level, a block can be shown as interconnected sets of routing and checking logic, finite-state machines, queues, and other primitive protocol machines. 在定义系统网络体系结构(SNA)协议机体中使用的一种基本表示方法,它可以把一个协议 机体分解而表示为许多组成子体(它们本身也是协议机体)以及它们之间通信的路径。实际 上,图中的每一框还可进一步分解为许多组成子体,按最细的划分,一框可表示成:相互连接 好了的若干路由选择及检查逻辑、限态机体、队列以及其它原始协议机体的集合。 |
