Method and device for adjusting bandwidth of transmission channel in flexible Ethernet

The invention discloses a method and device for adjusting the bandwidth of a transmission channel in a flexible Ethernet, and the method comprises the steps: sequentially increasing the bandwidth of each node according to the opposite direction of the flow direction of service data when the bandwidth of the transmission channel needs to be increased, and sequentially increasing the bandwidth of each node according to the opposite direction of the flow direction of the service data when the bandwidth of the transmission channel needs to be reduced. The bandwidth of each node is sequentially reduced according to the flow direction of the service data, so that in the process of adjusting the bandwidth of the transmission channel, the probability that upstream service data is transmitted to downstream to be lost is reduced, and the reliability of service data transmission is improved. 本申请公开一种灵活以太网中调整传输通道的带宽的方法和装置，在需要增大传输通道的带宽时，根据业务数据的流向的相反方向依次增加各个节点的带宽，以及在需要减小传输通道的带宽时，根据业务数据的流向依次减小各个节点的带宽，这样在调整传输通道的带宽的过程中，降低上游的业务
