Problems solved by technology

[0002] A large wireless network usually consists of multiple small local area networks. When a user roams between different local area networks, the IP (Internet Protocol, Internet Protocol) address of the wireless client device used by the user and the VLAN (Virtual Local Area Network, virtual local area network) will change, therefore, it is necessary to re-authenticate after disconnecting the network, resulting in poor user experience

Abstract

The present application provides an authentication method and device, the method comprising: when the IP address of the wireless client device changes from the first IP address to the second IP address, receiving an address change message sent by the wireless client device, and the address change message The text carries the MAC address and the second IP address of the wireless client device; find out whether there is a MAC address of the wireless client device in the MAC address white list, and the MAC address white list is used to record the MAC address of the authenticated wireless client device ; When there is a MAC address of the wireless client device, delete the first IP address in the IP address whitelist, and add the second IP address to the IP address whitelist. The IP address whitelist is used to record the authenticated wireless clients IP address of the end device. The application can avoid network interruption when wireless client devices roam across local area networks, and improve user experience.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to an authentication method and device. Background technique [0002] A large wireless network usually consists of multiple small local area networks. When a user roams between different local area networks, the IP (Internet Protocol, Internet Protocol) address of the wireless client device used by the user and the VLAN (Virtual Local Area Network, virtual local area network) will change, therefore, it is necessary to disconnect the network and re-authenticate, resulting in poor user experience. Contents of the invention [0003] In view of this, the present application provides an authentication method and device. [0004] Specifically, this application is achieved through the following technical solutions: [0005] This application provides an authentication method, which is applied to a wireless client device, and the method includes: [0006] Obtaini...
