A network node device, comprising:

• a computing hardware;
• and
• a non-transitory computer-readable storage medium including computer-executable instructions executed by the computing hardware to perform operations comprising:
• adjusting, according to bandwidth adjustment indication request information, the number of time slots occupied by an ODUflex frame in a Higher Order Optical Channel Data Unit (HO ODU), at an egress side of the network node device;
• and
• sending out, after the adjustment of the number of the time slots is completed, bandwidth adjustment indication request complete information.
