摘　　要：针对传统令牌环网通信机制中存在的不足,例如无法充分利用信道,需要不断维护令牌,3层交换网络中的转发跳数受生存时间(Time To Live,TTL)限制等,提出了一种在非令牌的环网通信中实现一跳转发数据的方法。该方法采用2层交换方式解除TTL限制,采用多生成树协议(Multiple Spanning Tree Protocol,MSTP)消除通信环路,并结合策略控制处理协议报文,最后通过真实的环网应用环境,验证该方法能实现数据一跳转发,且具有配置简单、使用灵活、拓展性强的特点,同时还减少了令牌的维护成本,从而能够更好地使用信道资源。In order to address the shortcomings of the traditional token ring communication mechanism,such as the inability to fully utilize the channel,the need for constant token maintenance,and the TTL(Time To Live)restriction on the number of forwarding hops in the Layer 3 switched network,a method is proposed to achieve one-hop data forwarding in a non-token ring communication mechanism.This method uses Layer 2 switching to remove TTL restrictions,uses MSTP(Multiple Spanning Tree Protocol)to eliminate communication loops,and combines policy control to process protocol messages.Finally,through a real ring network application environment,it is verified that the method can achieve one-hop data forwarding,and has the features of simple configuration,flexible use,and strong scalability,while also reduces the maintenance cost of the token,and can better use channel resources.
