摘要： An improved arbitration apparatus for a computer network of the type having a plurality of communicating nodes, the nodes communicating by a shared bus, wherein an arbitration apparatus located in each node, functions by assigning to each node an initial arbitration count number; the apparatus includes means, in each node, for testing for the presence of a carrier signal on the bus, indicative that another node is transmitting on the bus; and means, responsive to a number of counted quiet slots (when there is absence of carrier signed on the bus) equaling the arbitration count number, for beginning transmission of a message on the bus. Also, a means, responsive to a node winning an arbitration, changes the arbitration count number of each node. The apparatus reserves a specified quiet slot for a node having no knowledge of the history of arbitration to transmit it. Responsive to a node beginning communication during a deaf node quiet slot, the apparatus reassigns an initial set of arbitration count numbers to the nodes, for resetting a clock in each node.

摘要翻译： 一种用于具有多个通信节点的类型的计算机网络的改进的仲裁装置，所述节点由共享总线通信，其中位于每个节点中的仲裁装置通过向每个节点分配初始仲裁计数号而起作用; 该装置包括在每个节点中用于测试总线上载波信号的存在的装置，指示另一个节点正在总线上传输; 以及响应于多个计数的安静时隙（当没有在总线上签名的载波时）等于仲裁计数号的装置，用于在总线上开始发送消息。 此外，响应于赢得仲裁的节点的装置改变每个节点的仲裁计数。 该设备为不知道仲裁历史的节点保留指定的安静时隙以进行传输。 响应于在聋节点安静时隙期间开始通信的节点，该装置将初始的仲裁计数集合重新分配给节点，以重置每个节点中的时钟。
