Usage Guidelines

Usage Scenario

On a WLAN, the physical layer rates of users have great differences due to different radio modes supported by the terminals or radio environment where the terminals reside. If the users with lower physical layer rates occupy wireless channels for a long period, user experience of the entire WLAN is affected. Airtime fair scheduling calculates the channel occupation time of users transmitting the same service and preferentially schedules resources for the users who occupy the wireless channel for a shorter period. This ensures fairness in channel usage.

After airtime fair scheduling is enabled, the device collects statistics on the channel occupation time used by users connected to the same radio for sending packets, creates the mapping table for the channel occupation time of each user in accumulated mode, and establishes a sorted link table based on the time in an ascending order. Based on the mapping table, an AP transmits data with the user who occupies the channel for the shortest time, ensuring that each user can equally occupy the wireless channels. The data packets of high-speed users are transmitted quickly, which is not affected by the data transmission time of low-speed users. This improves the overall user experience.

After WMM is enabled on the device and terminals, user packets are scheduled based on different types (service types include VI, VO, BE, and BK). For example, voice packets are scheduled only with other voice packets, and video packets are scheduled only with other video packets.

Precautions

If the packets of multiple users are of different types, airtime fair scheduling is not performed. For example, two users perform packet transmission: one transmits voice packets and the other transmits video packets. In this case, airtime fair scheduling is not performed for the two users.

When the command is executed, the system displays the message "Warning: This action may cause service interruption. Continue?[Y/N]", asking you whether you want to continue.

Example

# Enable airtime fair scheduling in RRM profile default.
