A speed limiting method and device

Abstract

The present application provides a speed limit method and device. The method is applied to an AC. The method includes: when a wireless terminal goes online and determines the wireless terminal that needs speed limit, obtain the corresponding speed limit configuration information of the wireless terminal; if the speed limit configuration If the information includes uplink speed limit information, generate an uplink speed limit rule including the identification information of the wireless terminal and the uplink speed limit value corresponding to the wireless terminal included in the uplink speed limit information, and send it to the AP accessed by the wireless terminal, In order for the AP to limit the speed of the uplink traffic from the wireless terminal according to the uplink speed limit rule; if the speed limit configuration information includes the downlink speed limit information, generate a wireless The downlink speed limit rule corresponding to the downlink speed limit value of the terminal is configured on the speed limit execution module in the AC, and the downlink traffic sent to the wireless terminal is limited through this module. This application saves bandwidth resources between the AP and the AC.

Description

technical field [0001] The present application relates to the technical field, and in particular, to a speed limiting method and device. Background technique [0002] In a wireless local area network (Wireless Local Area Network, WLAN), in order to prevent an individual wireless terminal from occupying too much bandwidth and affecting the user experience of other wireless terminal holders, it is usually necessary to limit the speed of the wireless terminals accessing the WLAN. [0003] At present, in the scenario where the forwarding mode of the access point (AP) in the WLNA is the centralized forwarding mode, the rate limit rules set for wireless terminals are usually configured on the same device, for example, uniformly configured on the AC or on the AP. [0004] However, in practical applications, the communication between the AC and the AP is carried out through the established tunnel (for example, the Control And Provisioning of Wireless Access Points Protocol Specific...

AI Technical Summary

Problems solved by technology

[0004] However, in practical applications, AC and AP communicate through established tunnels (for example, Control And Provisioning of Wireless Access Points Protocol Specification, CAPWAP), and AC and AP may need Across multiple network devices or even across the public network

This will easily lead to the uplink traffic of the wireless terminal discarded after the rate limit is executed by the AC or the downlink traffic of the wireless terminal discarded after the rate limit is executed by the AP, which still occupies the bandwidth between the AC and the AP, wasting a lot of bandwidth resources
