Queue scheduling method and device

The embodiment of the invention provides a queue scheduling method and a device. In a queue scheduling polling, according to the current to-be sent grouping of the current scheduling active queue, the current to-be sent grouping is sent when the length of the current to-be sent grouping of the active queue is no longer than the average length of the current to-be sent groupings of the current all active queues; the difference value between the current maximal allowable sending quantity of the active queue and the length of the sent grouping is used for updating the current maximal allowable sending quantity corresponding to the active queue, and scheduling processing of other to-be sent groupings is carried out; when the length of the current to-be sent grouping of the active queue is larger than the average length of the current to-be sent groupings of the current all active queues, scheduling processing of the current to-be sent groupings of the next active queue is carried out; when no active queue exists, each corresponding maximal allowable sending quantity of each queue is updated, and scheduling processing of next polling is carried out. The invention relates to the field of network communication.
