Problems solved by technology

This method is not conducive to controlling user access and wastes AP resources.
2. Direct forwarding of user data to the uplink network cannot adapt to various flexible networking methods, or will destroy the existing network structure of operators
[0007] However, the switching between bridge mode and LOCALMAC mode is not flexible at present

Embodiment 1

[0025] Example 1 as figure 1 with figure 2 Shown: This embodiment is a method for implementing a standard CAPWAP tunnel on an AP. This method makes little change to the original AP process, and enables the AP to flexibly switch between bridge mode and local MAC mode, meeting the requirements for different working modes in different deployment scenarios, taking into account the actual deployment situation of the current network and the direction of unified standards in the future .

[0026] The technical solution adopted by the present invention for realizing the purpose of the invention is to create two virtual devices, one of which is responsible for the encapsulation and decapsulation of the tunnel format, and the other is responsible for the processing of the wireless message answered by the AC. Specific steps are as follows:

[0027] 1. After the system is started, the AP will create a virtual tunnel device and a virtual wireless device on the AP if the AP is required ...

Abstract

The invention provides a method for realizing a CAPWAP (Control and Provisioning of Wireless Access Points) tunnel. In the LOCALMAC mode, the uplink communication of a user and an AC (Access Controller) and the downlink communication of the AC to the user are realized. The uplink communication is that different user messages are packaged into different tunnel messages to be sent to the AC, and the downlink communication is that the different tunnel messages are sent to the user. According to the method, a standard CAPWAP tunnel on an AP (Access Point) is realized by judging whether the LOCALMAC mode is transferred into the LOCALMAC mode. According to the method, an original AP flow is slightly changed, so that the AP can be flexibly switched in a bridge mode and the LOCALMAC mode, the requirements for different working modes are met under different deployment scenes, and the actual deployment situation of the existing network and the direction of a unified standard in the future are met.

Description

technical field [0001] The invention relates to the field of wireless local area network (WLAN), in particular to a CAPWAP tunnel between an AP and an AC in the field of wireless local area network access, and to a communication mode between a wireless hotspot AP and an AC. Background technique [0002] With the development of society, users' demands on wireless access methods are increasing day by day. Operators have begun to pay more and more attention to the deployment of wireless hotspot APs (Access Points). In order to facilitate the management of a large number of hotspot APs, most of them adopt the deployment method of AC+AP, and the management of hotspot APs is handed over to the AC (AP Control AP controller). ) to proceed. [0003] Different manufacturers implement different communication methods between APs and ACs. As a result, APs and ACs from different manufacturers cannot communicate with each other. The CAPWAP protocol was born under this background. It stan...
