Specifically, a service configuration dependency point is established, service configuration is processed, and a dependency relationship is established with overhead configuration. Thus, the relay_act [0] associated overhead configuration uinq_index is defined, while the service configuration uinq_index is defined. Then, the single disk receives the OTN overhead configuration. Specifically, an overhead configuration dependency point is established, and a dependency relationship is required to be established with the protection configuration.

Referring to fig. 6, fig. 6 is a schematic diagram of a lossless networking structure of nodes according to an embodiment of the invention. As shown in fig. 6, node 1 is a tributary single disk, and nodes 1 and 2 create traffic by crossing. The node 2 comprises an XCU interleaving unit and an OTN line single-disk. Under the unprotected scene, the node 1 crosses to the OTN line disk (master) of the node 2; in the protection scenario, node 1 multicasts to the OTN line pad (primary) and the OTN line pad (standby) of node 2. The node 3 comprises an XCU cross unit and a main and standby OTN line single disk. In the unprotected scenario, the OTN line pad (master) optical fiber of node 2 is connected to the line pad (master) of node 3; in the protection scenario, the OTN chassis (master) of node 2 is connected to the chassis (master) of node 3, while the OTN chassis (standby) of node 2 is connected to the chassis (standby) of node 3.

In this embodiment, according to the dependency relationship between the nodes established in step S40, the node configuration sequence may be determined, so that each node is configured according to the determined node configuration sequence. For example, a node 4 dependency point is established, and a dependency relationship needs to be established with the node 3, so that a relationship_act associated node 3uinq_index is defined, and a node 3uinq_index is defined. The node 3 dependency point is established, and a dependency relationship needs to be established with the node 2, so that the relation_act associated node 2uinq_index is defined, and meanwhile, the node 2uinq_index is defined. The node 2 dependency point is established, and a dependency relationship needs to be established with the node 1, so that the relation_act associated node 1Uinq_index is defined, and meanwhile, the node 1Uinq_index is defined. Node 1 dependency points are established, defining node 1uinq_index. The establishment of the dependency relationship among the nodes is successful. Referring to fig. 7, fig. 7 is a schematic diagram of a lossless implementation structure of a node according to an embodiment of the present invention. As shown in fig. 7, according to the dependency relationship between nodes, first, the node (node 4) arranged first is configured; if the node 4 receives the ACK, configuring the node (node 3) arranged at the second position; if the node 3 receives the ACK, configuring the node (node 2) arranged in the third position; if the node 2 receives the ACK, configuring the node (node 1) arranged at the last bit; if the node 1 receives the ACK, the node configuration is determined to be completed.
