Embodiment Construction

[0044] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.

[0045] The CAPWAP protocol specifies the AP upgrade method. First, when the AP associates with the AC, the AC sends a Join Response message to the AP. The file version in the Join Response message triggers the AP to respond to the AC with a request for downloading the upgrade file, and performs an upgrade based on the upgrade file. Second, after the AP is associated with the AC, when the user thinks it is necessary to upgrade an AP, the AC will confirm the upgrade of the AP, so that the AC sends an upgrade command (Configurati...

Abstract

The invention provides an AP upgrade method and device. The method comprises the following steps: an AP to be upgraded receives a data block index table corresponding to an upgrade file and sent by an AC, wherein the upgrade file is divided into a plurality of data blocks through the AC, and the data blocks are stored to different upgraded APs respectively, and the data block index table comprises a mapping relation between the plurality of data blocks and the IP of the upgraded APs having the plurality of data blocks being stored therein; based on the data block index table, the data blocks are downloaded from the corresponding upgraded APs respectively; and the downloaded data blocks are jointed to form the upgrade file, and upgrading is carried out based on the upgrade file obtained through jointing. According to the AP upgrade method and device, the AP to be upgraded obtains the upgrade file from the upgraded APs instead of obtaining the upgrade file from the AC in the prior art, so that the AP upgrade time is allowed to be changed from linear growth to logarithmic growth, and with the increase of the number of the APs, the AP upgrade time is obviously saved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an AP upgrading method and device. Background technique [0002] AC (Wireless Access Point, wireless access point) is a network device, used to centralize the control of wireless AP (Wireless Access Point, wireless access point), is the core of a wireless network, responsible for managing the wireless network For all wireless APs, AP management includes: issuing configurations, modifying related configuration parameters, radio frequency only management, access security control, etc. CAPWAP (Control And Provision of Wireless Access Points Protocol Specification, wireless access point control and configuration protocol) specifies how the AP obtains the software version from the AC. Specifically, when the AC finds that the AP image version does not match, it will issue an upgrade command. Subsequently, the AP will receive image file fragments one after another...
