Method and device for wireless local area network service quality level control

Abstract

The invention discloses a method and a device for controlling the quality-of-service (QoS) level of a wireless local area network. The method comprises the following steps: receiving data flow from second-layer AP equipment, identifying business data flow which needs QoS control according to preliminary definition, and forwarding the business data flow; making DPI analysis of a data packet to acquire traffic data; collecting the traffic data, user data and equipment data, and carrying out association matching to obtain association matching information; using the association matching information to generate a strategy scheduling instruction for business service level control according to a predefined QoS control strategy; and executing the strategy scheduling instruction on the business data flow and injecting the business data flow into an original route so as to send the business data flow to third-layer network equipment. Through the technical scheme provided by the invention, multi-dimensional identification of wireless local area network equipment and user service as well as QoS level control based thereon are realized, and thus improvement of the quality of service and customer perception is ensured.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for controlling the service quality level of a wireless local area network. Background technique [0002] With the development of WLAN technology, more and more users choose WLAN to connect to the Internet of Things. see figure 1 as shown, figure 1 A schematic diagram showing the structure of the current wireless local area network networking mode, that is, a schematic diagram of the FIT architecture. Such as figure 1 As shown in , in step 1, the traffic generated by the terminal (Station, STA) is sent up by the Layer 2 access point (Access Point, AP) device to the Layer 3 wireless control (Access Control, AC) device, and the AC device is responsible for Control and manage the AP device, and perform connection management between the AC and the AP through the (Control And Provisioning of Wireless Access Points, CAPWAP) tunnel protocol; step 2, the servi...

Problems solved by technology

However, based on Layer 3 network address protection, only online users who obtain dynamic IP addresses after authentication can be controlled. When the IP address changes, it cannot be identified, and thus the quality of service cannot be controlled.

At the same time, this wireless LAN quality control solution can only provide single-latitude user service quality level control based only on IP addresses, and cannot provide accurate user service quality level guarantees.
