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.
【技術實現步驟摘要】
【技術保護點】
一種熱備冗余網絡系統,其特征在于,包括:不少于兩個的網絡節點以及與每個網絡節點唯一對應的冗余節點;每個網絡節點和每個冗余節點均包括四個網絡接口和一個交換接口,且四個網絡接口均具有相同的物理地址和邏輯地址,其中第一網絡接口和第二網絡接口形成第一冗余接口對,第三網絡接口和第四網絡接口形成第二冗余接口對;每個網絡節點和其對應的冗余節點之間通過所述交換接口連接,組成一個冗余節點對,且每個冗余節點對中冗余節點的物理地址和邏輯地址,均與該冗余節點對中網絡節點的物理地址和邏輯地址相同;每一個冗余節點對中,網絡節點的第一網絡接口連接到其相鄰一側的冗余節點對中網絡節點的第三網絡接口,第二網絡接口連接到上述相鄰一側的冗余節點對中冗余節點的第三網絡接口;冗余節點的第一網絡接口連接到上述相鄰一側的冗余節點對中網絡節點的第四網絡接口,第二網絡接口連接到上述相鄰一側的冗余節點對中冗余節點的第四網絡接口;多個冗余節點對按照上述方式依次相連接,構成線形網格狀結構。
