Abstract
The embodiments of the present application relate to the field of communications technologies, and disclose a method for adjusting bandwidth of a flexible Optical channel Data Unit (ODUflex) channel. The method includes: respectively adjusting, according to a bandwidth adjustment indication message, a quantity of time slots occupied by an ODUflex frame in a higher order optical channel data unit (HO ODU) at an egress side of each network node on an ODUflex channel; and adjusting, according to a rate adjustment indication message, a transmission rate of the ODUflex frame of each network node on the ODUflex channel, so as to unify the transmission rate of each network node on the ODUflex channel.
