Load balancing method for APs to access cloud ACs based on capwap

Abstract

The invention discloses a load balancing method for APs to access cloud ACs based on capwap. The load balancing method for each AP to access the corresponding cloud AC based on the capwap comprises the following steps of S110.reading cloud AC cluster state information first; S120.if at least one cloud AC node is included, entering S130, otherwise making the AP enter an end state directly; S130.making the AP select one cloud AC node to establish a connection; S140.if the connection is successful, entering S150, otherwise entering S160; S150.sending a capwapdiscovery message by the AP, and thenentering S170; S160.reselecting an available cloud AC node connection; S170.judging whether the cloud AC node responds to a capwap discovery request or not; S180.updating the cache by the AP, and entering S190; S190.if the currently selected cloud AC node is the available node, entering S200, otherwise entering S160; and S200.completing capwap process interaction, and ending an online process of the AP. According to the method, the connection load balancing of a cloud AC cluster is achieved, the situation that a certain cloud AC node is slow in response and even breaks down due to high load isavoided, and the overall online time of all AP equipment is shortened.

Description

technical field [0001] The present invention relates to the field of wireless local area network (WLAN, Wireless Local Area Network), in particular to a wireless access control device (AC, Access Control) for a client to access a wireless access point (AP, Access Point) to a cloud AC cluster node Which cloud AC node is adjusted in order to achieve capwap-based AP access cloud AC load balancing method. Background technique [0002] With the popularization of intelligent wireless terminals and the increase of users' demand for wireless networks, the scale of WLAN (Wireless Local Area Network) is constantly expanding. In the WLAN centralized network architecture, the mode of single AC (wireless access controller) controlling AP (wireless access point) introduces multiple ACs due to problems such as forwarding bottlenecks. In a single-AC system, APs are managed by the same cloud AC, and there is no need to care about the ownership of APs. For multi-AC systems, especially the i...

Problems solved by technology

However, due to factors such as the suddenness of network traffic and the unbalanced user traffic on each AP, the load of the AC cannot be fully grasped only from the number of APs managed by the AC at the current moment and the network traffic of the AC. Therefore, The load of AC needs to be considered globally to reduce the imbalance of AC load
