【摘要】 <正> 在分布式系统中,当多个设备共享资源或多路复用某一信道时,常会发生端口或信道访问冲突(或争用)。通常可用仲裁机构来解决冲突。例如,发现冲突后便发出阻塞信号,然后令各设备随机延迟一段时间后访问信道或共享资源。也可采取某种优先仲裁准则,如按设备地址的各比特的优先等级仲裁等。更高级更多还原

【Abstract】 The conflicts resulted from the devices to access shared ports or channels can be solved by a method of randomly competitive arbitrating. The competition states among a set of identification codes can be described by a state transition diagram. Code patterns will affect the fairness of the competitions which may be fare or unfair depending on the code assignments and requirements. The results of computer simulation coincide with the theoretic calculations.更多还原
