Packet ring network system node redundancy methods, interface card, interface devices, and node device

摘要

Nodes arranged as a redundant node, set the message packet and the common address is used in common with redundant node other packet ring network, redundant node configuration information indicating that the own node is set as a redundant node, Each node on the ring that broadcasts the packet ring network the message packet, receives the message packet, sets a common address used in redundant node and the presence of a redundant node ring topology table within its own node, redundant Set the common address redundant node to use as the destination address of the packet to the packet transmission when the node addressed, and transmits it to the packet ring network the packet.
