摘要： 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.

摘要： 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.
摘要翻译：提供带宽调整方法和通信节点。所述调整方法包括：由上游入口单元向所有下游分支出口单元发送调整信令的一组多信道并行基本交换小区; 当确定所有下游分支出口单元返回的调整响应状态是接收确认时，发送正常信令; 在下游分支出口单元接收到正常信令后，根据调整信令将基本交换单元加入或移出下一组多通道并行基本交换单元; 并将下游分支出口单元发送的HO ODU的时隙调整到下游节点，并指示下游节点调整HO ODU的时隙。通过该方法和通信节点，实现了点对多点OTN非对称带宽载波系统中的无损带宽调整。
