token packet

基本解释

When the packet has timed out and purged from the cache, change the error message from previously processed to token expired.
当包已经超时并从高速缓存中被清除时，将错误消息从先前已被处理更改为令牌失效。
A packet sniffer for a token ring network could detect that the token has been lost or the presence of too many tokens (verifying the protocol).
一网络分析的令牌环网络可以检测到令牌已遗失或存在太多的凭证（核查协议）。
However, the cable does in fact form a ring, and Token Ring uses a somewhat complex token passing system to determine which computer gets to send a packet at which time.
但是这些线路确实组成了一个环型结构。令牌环网使用了一个复杂的令牌传递系统，以此决定是哪一台计算机、在什么时候可以发送数据封包。
