Embodiment Construction
[0026] The embodiments of the present invention are applicable to the transmission processing scene of the OTN network system, especially to the scene of intercommunication between multiple OTN management domains. The following embodiments illustrate the present invention by taking the application in cross-OTN management domains as an example. see figure 1 , Operator B has two networks B1 and B2 respectively in two places. Operator B leases the network transmission channel of operator A, and operator B connects networks B1 and B2 through the leased transmission channel. The management overhead between each adjacent node in the networks B1, B2, and A is stored in the overhead area of the optical transmission frame of each network. In order to manage the networks B1 and B2 as a whole, the operator B needs to transmit the optical transmission frame overhead of the OTUs in the networks B1 and B2 in the network of the operator A. In this embodiment, the management overhead of t...
