摘要： 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.

摘要： Examples of the present disclosure provide a dual-homing protection method and device. In the dual-homing protection method, a forwarding item synchronizing channel and a data transfer channel are established between two Provider Edge (PE) devices in a dual-homing node, a Pseudo Wire (PW) and a Label Switched Path (LSP) protection group bearing the PW are established between a network side peer PE device and the two PE devices in the dual-homing node, which are taken as a logical device, so as to implement LSP protection within a network. The present disclosure may enable the protection within a network to be independent of access link protection. Subsequently, the management is simple.
