Description

A kind of method and apparatus of many AP tests

Technical field

The present invention relates to the communications field, particularly a kind of method and apparatus of many AP tests.

Background technology

At WLAN (Wireless Local Area Network, WLAN (wireless local area network)) during technology is used, the wlan network framework can be divided into two kinds, a kind of is " fat " AP ((Wireless) Access Point, (wireless) access points) network architecture, a kind of is " thin " AP network architecture.Traditional " fat " AP framework is the distributed frame of core with smart access point " fat AP ".The conspicuous problem that it faces: to AP must manage one by one, single carrying out; Can not carry out flow, radio frequency, user's distribution etc. to whole wireless network and carry out global administration.

Referring to Fig. 1, " thin " AP network architecture is by AC ((Wireless) Access controller, (wireless) network controller) all AP by the cable network centralized control second line of a couplet, thin AP architecture has been realized the centralized planning of wireless network and deployment, wireless controller has been finished the centralized management to all AP, and the more flow of whole net, radio frequency, user's etc. management function is provided, guaranteed that network-efficient stably moves.

In " thin " AP framework, AC is in order to realize the management to AP, and sets up a CAPWAP (Control And Provisioning of Wireless Access Point Protocol, wireless access point control and configuration protocol) tunnel between each AP.AC is to realize by CAPWAP tunnel to the management of AP, and after the data message of wireless client arrives AP, and AP also is that the encapsulate forwarded by CAPWAP tunnel goes up the visit that could realize internet (internet) to AC.
