Problems solved by technology

[0014] It can be seen that the above solution implements the file download function inside the CAPWAP protocol, which increases the complexity of the CAPWAP protocol.
[0015] The CAPWAP protocol is a protocol that an AC can manage multiple APs. From a practical point of view, it is very common for an AC to manage hundreds or thousands of APs. When a large number of APs are upgraded at the same time, it will cause great performance to the AC. pressure

Embodiment approach

[0030] First, a general description will be given of an upgrade method in a wireless local area network according to an embodiment of the present invention.

[0031] figure 2 and image 3 It is a network topology diagram for explaining the upgrade method in the wireless LAN according to the embodiment of the present invention.

[0032] exist figure 2 In the shown network topology, each switch (switch) is connected to 24 APs, and there are 40 such switches in total, so there are 960 APs that can be connected to in total. That is, the AC manages 960 APs. Assuming a most extreme situation, these 960 APs request an upgrade to the AC at the same time. If the AC replies corresponding packets to these 960 APs at the same time, and these 960 APs download files from the AC at the same time, it will cause great performance pressure on the AC.

[0033] Therefore in the present invention, adopt as image 3 The method shown is for upgrading. In general, the 960 APs to be upgraded ...

Abstract

The invention discloses a wireless local area network upgrading method which is composed of a wireless controller and a wireless access point, the method comprises the following steps: firstly, download an upgrading file from an AC by utilizing a file transfer protocol (File Transfer Protocol, FTP) or a trivial file transfer protocol (Trivial File Transfer Protocol, TFTP) by a first batch of APs which is composed of a few APs of a large batch APs; download the upgrading file from the first batch of APs by other APs except the first batch of APs by utilizing the FTP or the TFTP.

Description

technical field [0001] The invention relates to an upgrading method of a wireless local area network, in particular to an upgrading method of a wireless local area network based on a thin AP framework. Background technique [0002] The product architecture of a wireless local area network (Wireless LAN, WLAN) has evolved from a single autonomous wireless access point (Access Point, AP) to a centralized control system composed of a wireless controller (Access Controller, AC) and an AP. Generally, a single autonomous AP is called a fat AP, and an AP in a control system composed of an AC and an AP is called a thin AP. The purpose of this evolution is to separate access control, including authentication and confidential communication, mobility management, and radio frequency management, from a single AP, and be centrally controlled by the AC. [0003] Control And Provisioning of Wireless AccessPoints (CAPWAP) is a WLAN centralized control architecture framework protocol propose...
