Abstract

The invention provides a quick service switching method and device. The quick service switching method is used for an access switch connected with access point equipment in a wireless network. The method comprises the following steps that: an access switch determines that each uplink connected to a core switch fails; the access switch identifies a linkage downlink port of the faulty uplink; the linkage downlink port is an Ethernet power supply port connected with the wireless access point equipment; the access switch sets the linkage downlink port to be closed down, and stops Ethernet power supply through the linkage downlink port, and therefore a user accessed by the wireless access point equipment connected with the linkage downlink port is switched to another wireless access point.

Description

Technical field[0001]This application relates to communication technology, specifically a method and device for fast switching of servicesBackground technique[0002]With the development of network technology, more and more networks are deployed wirelessly. Generally, PoE (Power over Ethernet) switches are used to connect AP (Access Point) at the access layer. The switch port enables the PoE function to directly supply power to the AP, but when the upstream link to the internet or the network fails, making it impossible to access the internet (Internet), the downstream AP cannot quickly sense it, and users who establish a wireless connection with the AP still Obtaining a strong Wi-Fi (Wireless Fidelity) signal, but can no longer access the network, causing the user terminal to be unable to quickly switch to other effective APs to access the network, so it becomes vital to solve this problem.[0003]figure 1 As shown in one of the commonly used wireless networking scenarios, the core swi...
