Load sharing adjustment method and device for local access controller

Abstract

Embodiments of the invention provide a load sharing adjustment method and device for a local access controller. A central AC can compute a flow load value of each local AC based on acquired service port flow information of each local AC, flow loads of the two local ACs whose difference value of the flow load values is larger than a first preset threshold value are unbalanced, at the moment, accessadjustment is carried out on an AP accessed to the local AC with the larger flow load value dynamically, and the AP accessed to the AC with the larger flow load value is shared to the AC with the small flow load value, so that a purpose of balancing the load flow on the two local ACs is achieved.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a load sharing adjustment method and device of a local access controller. Background technique [0002] With the advent of the mobile Internet era, wireless data traffic has shown explosive growth, and major operators are increasingly relying on wireless local area networks (English: Wireless Local Area Networks, WLAN for short) to carry these wireless data traffic. A traditional WLAN usually adopts a networking architecture of an access controller (English: Access Controller, AC for short) + a wireless access point (English: Access Point, AP for short). The APs in this networking architecture are thin APs, which are only used to receive and transmit data traffic. The AC needs to manage, debug, and control the APs. However, as the scale of WLAN becomes larger and larger, the number of APs to be managed by an AC continues to increase, which makes the link bandwidth betwe...

Problems solved by technology

[0004] For a local AC, the AP usually connects to the local AC in a load-sharing manner. However, in some special scenarios, for example, the first floor of a company’s office building is a public area, the corresponding AP is connected to the AC. There are many terminal devices on the local AC on the first floor, and the leader’s office area on the second floor, so there are few terminal devices connected to the local AC on the second floor through corresponding APs, resulting in unbalanced load traffic on different local ACs, which is not conducive to the health of the entire network. run
