The present invention provides a method and a node for adjusting a line interface rate. The method includes: determining, by a first node, an adjustment requirement for a line interface rate; and according to the adjustment requirement for the line interface rate, adjusting, by the first node, a transport bandwidth of an optical channel OCh link, adjusting the number of optical channel transport lanes OTLs in an optical channel transport unit OTUCn link, and adjusting the number of optical channel data lanes ODLs in an optical channel data unit ODUCn link, where the OTL is in one-to-one correspondence with the ODL. In embodiments of the present invention, according to an adjustment requirement for a line interface rate, a transport bandwidth of an OCh link is adjusted, the number of OTLs in an OTUCn link is adjusted, and the number of ODLs in an ODUCn link is adjusted, so that the line interface rate can be dynamically adjusted. |
