Abstract: The present invention discloses a bandwidth adjustment method and a related device, so as to flexibly adjust a bandwidth. A controller obtains behavior characteristic statistics sent by an end cloud node device, and obtains bandwidth resources remaining on a system. The behavior characteristic statistics are a statistical result indicating behavior characteristics of occupying network bandwidth resources by a user when accessing the end cloud node device.
