Service quality processing method and apparatus

Abstract

The invention discloses a service quality processing method and apparatus. The method comprises the following steps: according to an air interface sending rate, determining the packet taking rate of taking data packets from each priority queue of a service level, wherein the packet taking rate is not greater than the air interface sending rate; according to the packet taking rate, from each priority queue of the service level, according to a high-to-low priority sequence of the data packets, taking out the data packets for placing into a driving software queue; placing the data packets in the driving software queue into a hardware queue; and according to the air interface sending rate, sending the data packets from the hardware queue to an air interface. According to the scheme provided by the invention, data packets with high priorities can be sent timely, the phenomenon of drop of the high-priority data packets due to congestion of the driving software queue does not occur, and QoS is well guaranteed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for processing quality of service. Background technique [0002] Wireless Local Area Networks (WLAN) devices send data packets to the air interface, such as figure 1 As shown, it usually includes the following steps: the business level generates the data message to be sent, and sends it to the driver software; the driver software performs the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11a / b / g / n protocol media access control ( The MediaAccessControl (MAC) layer is implemented by software, and then sent to the WLAN module hardware; the WLAN module hardware completes the related processing of the MAC layer by hardware, and then performs physical layer processing, and finally sends the data packet to the air interface. [0003] In order to meet the different Quality of Service (QO...

AI Technical Summary

Problems solved by technology

[0011] Although the data packets sent by the service level are sorted according to strict priority, the driver software fetches packets at the maximum rate, only to meet the limit of the maximum depth of the driver software queue, and the changing air interface rate will lead to the data packets fetched into the driver queue They cannot be sent to the hardware queue immediately and sent out from the air interface, causing data packets to be arranged out of order in the priority of the driver software queue, and finally low-priority data packets may be sent from the air interface before high-priority data packets

In addition, the delay of data packets after queuing will also increase, and the delay jitter will also deteriorate.

Even high-priority data packets are discarded because low-priority data packets have filled the driver software queue and cannot be queued, which cannot guarantee the QOS of the service
