But the bits to bits arbitration of the CAN protocol defines a static priority to messages exchanged. Due to the fact of the lack of timing information for non periodic data transmission, it is impossible to find a static manner to attribute CAN identifiers to exchanged objects so that applications periods limit can be always be satisfied. When one or many network stations send data using the same identifier, at some point, data will differ and generate error. All stations will then back off and retransmit restarting the whole process. In this case, retransmission can lockup the network.

然而， CAN总线采用位仲裁技术，利用信息的标识符域定义了一种静态的优先权，由于非周期数据传输时缺乏时间信息，不可能找到一个静态标识符分配方案永远满足应用程序对时间的要求；当一个或多个网络节点同时发送标识符相同的数据时，如果数据不同，所有节点都要重新发送数据，在这种情况下，网络将阻塞。
