Patent ID: 8064334

Claim:
A method for implementing an intersecting ring network with arbitrary topology, comprising: intersecting multiple Ethernet rings to form the intersecting ring network with arbitrary topology, mapping each Ethernet ring in the intersecting ring network into a layer, the layer of the Ethernet ring being one of the layers from the most inner layer to the most outer layer; and 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 a port, wherein the protocol message interaction in the intersecting ring network comprises, a node of any Ethernet ring in the intersecting ring network sending out a protocol message carrying layer information of the Ethernet ring where the node is located, a transmission node in the intersecting ring network forwarding the protocol message through other unblocked ports after receiving the protocol message from one port, and a master node in the intersecting ring network, forwarding the protocol message through other unblocked ports when receiving the protocol message from an outer layer ring through an unblocked port, or performing relevant processing according to the protocol message and not forwarding the protocol message when receiving the protocol message from the current layer ring of the master node, or directly discarding the protocol message when receiving the protocol message from an inner layer ring.
