Method and device for processing quality of service

Abstract

The invention discloses a method and device for processing quality of service. The method includes: according to the transmission rate of the air interface, determining the packet fetching rate for fetching data packets from each priority queue at the service level; wherein, the packet fetching rate is not greater than the air interface transmission rate; according to the packet fetching rate, From each priority queue of the business level, according to the order of the priority of the data message from high to low, take out the data message and put it into the driver software queue; put the data message in the driver software queue into into the hardware queue; and send the data packet from the hardware queue to the air interface according to the transmission rate of the air interface. This solution not only enables high-priority data packets to be sent in a timely manner, but also prevents high-priority data packets from being discarded due to the full queue of the driver software, which ensures business continuity. QoS.

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 implements the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11a / b / g / n protocol The media access control (Media Access Control, MAC) layer is processed 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 Send to air. [0003] In order to meet the user's requirements for different Quali...

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
