ACCESS CONTROL FOR COMMUNICATION NETWORKS |
摘要 |
An active repeater for a star configured communications network includes a threshold detector for collision detection. Whenever two or more terminals simultaneously feed data into the repeater, a threshold sensitive collision detector is triggered to logically isolate the data from the output of the repeater and to logically substitute a predetermined collision signal therefor, thereby causing the competing terminals to reset to retry the transmissions at randomly selected later times. |
