Abstract: In the field of optical communications, a method and a device for adjusting transmission of transport network data are provided. The method includes the following steps. Information of adjusting a designated Optical Transport Network (OTN) line sent from an OTN is received. The OTN line corresponding to the information of adjusting the designated OTN line is adjusted. Changed data traffic of the adjusted OTN line is calculated. An Ethernet channel to be adjusted according to the changed data traffic is designated, and the Ethernet channel to be adjusted is adjusted correspondingly. The device includes a Link Capacity Adjustment Scheme (LCAS) module and a channel processing module. According to the method and the device, the adjustment of the OTN line is associated with the adjustment of the Ethernet channel, thereby ensuring the data transmission efficiency, and improving the overall performance of a network.

Abstract: A bandwidth adjusting method and a communication node are provided. The adjusting method includes: sending, by an upstream ingress unit, a group of multi-channel parallel basic switch cells in which adjustment signaling is carried to all downstream branch egress units; sending normal signaling when determining that adjustment response statuses returned by all the downstream branch egress units are reception acknowledgment; after receiving the normal signaling by the downstream branch egress unit, adding or removing the basic switch cell into or from a next group of multi-channel parallel basic switch cells according to the adjustment signaling; and adjusting a time slot of an HO ODU sent by the downstream branch egress unit to a downstream node, and instructing the downstream node to adjust the time slot of the HO ODU. Through the method and the communication node, lossless bandwidth adjustment in a point-to-multipoint OTN asymmetric bandwidth carrier system is implemented.
