The embodiment of the invention discloses a can be used in real time Ethernet redundant hot standby redundancy network system and its implementation method, including redundant network system, the hot standby: not less than two network nodes and redundant nodes and each node only corresponding to each network node; and each node includes four network redundancy interface and an exchange interface, four network interfaces have the same physical address and logical address, and the four network interface 22 two redundant interface of redundant nodes, network nodes and their corresponding via the exchange interface connection, composed of redundant nodes, redundant nodes adjacent to the network nodes and redundant nodes connected through the cross network interface. This scheme can make the real-time Ethernet failure rate to increase the number of nodes in the network is not sensitive, without the need for real-time Ethernet data packet format to make any changes, can significantly reduce the failure rate of real-time Ethernet, the redundancy and availability can be greatly improved.
