传统上，解决冲突的方法是采用MAC协议控制数据包接入信道和冲突后的重传管理。
Traditionally, MAC protocols are used to control channel accessing and manage retransmissions after collision.
以此为依据进行多令牌管理，规定只有持有令牌的节点才能访问信道，从而实现具有安全性保障的介质访问控制。
The management mechanism regulates that a node can access the channel only when it holds a token, by which the protective mechanism with media access control can be realized.
