  • Redundant network implementation method
    Patent number: 9432250
    Abstract: Disclosed is a method of implementing a redundant network. Ring network nodes in an initial state are set as master stations, ring ports are set in a half-blocked state, a master station election notification message is broadcast to the ring ports within a preset time interval, the nodes receive the master station election notification message, a node quality comparison vector is compared with node quality comparison vectors of the nodes to elect a master and standby stations, one of the ring ports is in the half-blocked state, the other ring ports are in a forwarding state, the master station broadcasts the master station election notification message to the ring ports, the standby master station stops sending the master station election notification message, the ring ports are in the forwarding state, and the message sent by the master station is received.
