A control information frame that controls each station in the network to send information through a communication medium, that is, a token frame. Only the station that has obtained the token frame can send information. There are two ways to use the token mechanism to access the communication medium: token passing suitable for token bus networks and token ring suitable for token ring networks. The token length is composed of three bytes, which are pre-mark, start delimiter and frame control.【对网络中各个站通过通信介质发送信息进行控制的一种控制信息帧，即令牌帧。只有获得令牌帧的站才能发送信息。使用令牌机制访问通信介质分为两种方式：适用于令牌总线网的令牌传递和适用于令牌环网的令牌环形。令牌长度由三个字节组成，分别是前标、起始定界符和帧控制。】
