1. A service level adjustment method implemented by a first network device, wherein the service level adjustment method comprises:
obtaining at least one piece of queue status information of a queue bound to a target service level of the first network device;
adjusting a parameter of the target service level based on a maximum delay associated with the target service level when any piece of queue status information of the at least one piece of queue status information exceeds a first threshold upper limit, wherein the parameter of the target service level comprises a queue resource parameter and a data flow constraint parameter, and wherein the data flow constraint parameter comprises a threshold of a burst amount of a data flow entering the queue and a threshold of an average rate of the data flow;
reporting exception information to a control device when an update value of the parameter does not meet a constraint condition of a local target resource and when the maximum delay remains unchanged, wherein the local target resource is a resource that is able to be preempted by the target service level;
receiving a first adjustment value that is of the parameter and that is received from the control device, wherein the first adjustment value is based on the exception information; and
adjusting the parameter based on the first adjustment value of the parameter.
