The invention discloses a queue scheduling algorithm. The algorithm comprises the steps that all queues are initialized; the weight of each queue is set and stored; the virtual time of a system and the virtual start time and virtual end time of each queue are set; whether a packet reaches an empty queue is judged; if a packet reaches an empty queue, the virtual start time and the virtual end time are recalculated, and the system virtual time are updated; whether a burst service is in the queues is judged; if the burst service exists, the weight of the queue with the burst service is adjusted; the virtual start time and the virtual end time are recalculated, and the system virtual time is updated; and packet scheduling is carried out according to a packet selection policy of the minimum qualified virtual completion time priority. According to the queue scheduling algorithm provided by the invention, a delay guarantee is provided for a high priority traffic flow by introducing virtual delay; by adjusting the weight of the queue with the burst service, a weight adjustment mechanism is introduced to ensure that the burst service can timely and effectively scheduled; the packet loss rate is reduced; and the scheduling efficiency is improved.
