中文摘要本发明涉及一种高可用性工业以太网冗余方法,包括以下步骤:在以太网原有数据链路层上增设链路冗余实体,用于管理以太网数据帧的发送和接收;相对于原始协议栈设置两个网络适配器驱动,用于管理两个网络适配器接口;通过两个网络适配器将包含链路冗余实体和两个网络适配器驱动的双连接节点分别连接到两个独立的网络上;在链路冗余实体上为数据帧添加冗余控制跟踪器用以区别具有相同内容的数据帧;双连接节点通过两个网络适配器发送具有相同内容的带有冗余控制跟踪器的数据帧至两个相互独立的网络上;保存有效帧,丢弃副本帧;建立节点表。本发明具有透明性、自愈性、兼容性等特点,改造简单,增加系统的安全性能,使系统具有高可用性。

英文摘要The invention relates to a high-availability industrial Ethernet redundancy method, which comprises the following steps: adding a link redundancy entity on an original data link layer of the Ethernet for managing the sending and receiving of data frames of the Ethernet setting two network adapter drivers relative to an original protocol stack for managing two network adapter interfaces connecting a double-connected node which comprises the link redundancy entity and the two network adapter drivers to two independent networks respectively through two network adapters adding a redundancy control tracker for the data frames on the link redundancy entity for distinguishing the data frames with the same content sending the data frames which have the same content and is provided with the redundancy control tracker to two mutually-independent networks by the double-connected node through the two network adapters keeping effective frames and discarding copy frames and setting up a node table. The method has the characteristics of transparency, self-healing property and compatibility and the like and the reconstruction thereof is simple, and the safety performance of the system is increased so as to enable the system to have high usability.
