The embodiments of the present disclosure disclose a VOQ authorization management method and device and a computer storage medium. The method includes that: an index of a scheduling unit at next scheduling level is determined according to a scheduling algorithm of a scheduler of a scheduling unit directly connected with a physical port and a weight and priority of the scheduling unit at the next scheduling level of the scheduling unit, scheduling linked list information of each scheduler of the scheduling unit at the next scheduling level is acquired, and an index of a scheduler to be authorized corresponding to the same service grade with a current authorization in the scheduling unit at the next scheduling level is determined according to the scheduling linked list information until an index of a VOQ to be authorized corresponding to the same service grade with the current authorization is determined.
