Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0022] When a large number of APs access the AC at the same time, it will bring a great load to the AC. The present invention adds a coordination process between the AC and the AP, so that the APs can access the AC in an orderly manner, thereby avoiding the burden on the AC caused by the simultaneous access of a large number of APs. coming shock.

[0023] see figure 1 , figure 1 It is a flow chart of AP accessing AC in a specific embodiment of the present invention. The specific steps are:

[0024] In step 101, the AC receives a discovery request message sent by any AP.

[0025] The AC will receive discovery request messages sent by a large number of APs, and the processing procedure of the present invention is the same for any AP. ...

Abstract

The invention discloses a method for accessing an access pint (AP) into an access controller (AC) in a local area network, which comprises the following steps that: the AC receives discovery request messages sent by any one AP and sends discovery response messages carrying the waiting time to the AP, wherein the waiting time is determined according to the self central processing unit (CPU) load of the AC and the association priority of the AP and is used for notifying the AP to randomly select a waiting time in the waiting time, and datagram transport layer security (DTLS) connection requests are sent when the randomly selected waiting time is reached after the discovery completion for carrying out the access. Based on the same invention idea, the invention also provides the AC and the AP. The problem of simulation correlation of the AC by a large number of APs can be avoided, and convenience is brought for the network maintenance.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for accessing a wireless controller (AC) from a wireless access point (AP) in a wireless local area network, the AC and the AP. Background technique [0002] In a large WLAN network, an AC often needs to manage thousands of APs. In such a network, when the entire network needs to be restarted, thousands of APs will associate with the AC at the same time, and the AC needs to authenticate each AP and establish a session, which imposes a huge burden on the CPU of the AC. Once the CPU cannot process the AP association in time, the AP association process will fail, and the AP will soon re-associate with the AC, resulting in repeated failures. That is to say, the process of APs associating with ACs will be a process of repeated oscillations, and it will take a long time to realize that all APs are completely associated with ACs. This situation is especially obvious wh...
