Disclosed is a data transfer method, comprising: receiving first control information sent by an upstream node and receiving the OB sent by the upstream node taking the defined period as reference, wherein first marker information corresponding to the OB is included in the first control information; querying a marker forwarding table according to the first marker information to acquire the forwarding information about the OB; and forwarding the OB at the optical layer according to the forwarding information. Also disclosed are a corresponding node and a transfer system. During the implementation of the embodiments of the present invention, forwarding the OB according to the forwarding table is advantageous for realizing statistical multiplexing of bandwidth and improving the utilization efficiency of resources and further improving the throughput rate of the network, that is, increasing the optical layer forwarding ability and performance of the communication network. |
