ABSTRACT:
The present invention discloses a method for implementing an intersecting ring network with arbitrary topology, node and an intersecting ring network. The method includes: intersecting multiple Ethernet rings to form the intersecting ring network with arbitrary topology, each Ethernet ring in the intersecting ring network comprising a master node and multiple transmission nodes; the master node of each Ethernet ring opening its primary port and blocking its secondary port during initial normal operation; and the master node of each Ethernet ring in the intersecting ring network performing fault detection and fault processing as well as fault recovery detection and fault recovery processing by using one of the two manners containing protocol message interaction and detection on links directly connected to the master node.
