Method for realizing convergence of WAPI and CAPWAP in local MAC mode

Abstract

The invention relates to a method for realizing the convergence of WAPI and CAPWAP in a local MAC mode. The method comprises the following steps: 1, building the local MAC mode: the MAC function and the WAPI function of wireless access points are separately set in a wireless terminal point and an access controller respectively; 2, realizing CAPWAP specifications binding WAPI protocol in the localMAC mode: 2.1, an relevancy connection process among sites, the wireless terminal point and the access controller; 2.2, an announcement process of starting the WAI protocol between the access controller and the wireless terminal point; 2.3, an implementation of the WAI protocol among the sites and the access controller; 2.4, an announcement process of ending the WAI protocol between the access controller and the wireless terminal point; and 2.5, a process of secret communication by using WPI among the wireless terminal point and the sites. The method of the invention not only meets the needs for the wide scale deploymentof WLAN, but also guarantees the security of WLAN in a convergence type system structure.

Description

technical field [0001] The invention relates to a method for realizing the fusion of WAPI and CAPWAP in a local MAC mode. Background technique [0002] The wireless access point AP (Access Point) in the wireless local area network (WLAN) of the autonomous architecture is fully deployed and terminated with the GB15629.11 function. As a separate entity on the network, it needs to be independently managed. At present, WLANs designed based on WLAN Authentication and Privacy Infrastructure (WAPI) all adopt an autonomous architecture, but with the expansion of WLAN deployment scale, the network working mode of this autonomous architecture has its inherent defects It has gradually become an obstacle that restricts the development of wireless technology. [0003] First, in the WLAN of the autonomous architecture, the AP, as an Internet Protocol (Internet Protocol) addressable device, needs to be independently managed, including monitoring, configuration, and control. When a large-...

AI Technical Summary

Problems solved by technology

In a large-scale WLAN, the workload of updating the dynamic configuration of APs on the entire network in time is very heavy, and even impossible

[0005] Third, in WLAN, the wireless transmission medium is a shared resource. In order to improve the performance of the network, each AP must be monitored in real time and the configuration of these APs must be dynamically updated according to the current usage of the shared medium. Manual configuration and wireless transmission Medium-related AP parameters will consume a lot of manpower and material resources

[0006] Fourth, in WLAN with autonomous architecture, it is also difficult to securely access the network and prevent illegal APs from joining

It can be seen that the working mode of the autonomous architecture WLAN can no longer meet the deployment requirements of large-scale networks, and it is urgent to design a WAPI-based convergent WLAN network architecture, that is, the WAPI thin AP architecture
