WiFi communication system deployed with cloud ACs (access controllers) and communication method adopting WiFi communication system deployed with cloud ACs

Abstract

The invention provides a WiFi communication system deployed with cloud ACs (access controllers) and a communication method adopting the WiFi communication system deployed with the cloud ACs (access controllers). The WiFi communication system comprises a plurality of cloud ACs, an AC proxy server used for performing load balancing treatment on data streams, and an AP (access point) communicated with the cloud ACs by the AC proxy server, wherein the CAPWAP (Control And Provisioning Of Wireless Access Points) follows between the AP and each AC proxy server, and the IP (internet protocol) address of the AC proxy server is opened to the AP, so that the AP can find the AC proxy server after being electrified. According to the system, other private protocols are not required to be expanded to the AP, so that the development cost is reduced on the basis of the cloud ACs, besides, the cloud ACs are not exposed to a client side, the ACs can be well hidden and the security of the ACs is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a WiFi communication system and a communication method deployed with a cloud AC. Background technique [0002] At present, the trend of software-defined network (Software Defined Network, SDN) and network function virtualization (Network Function Virtualization, NFV) based on virtualization technology is becoming more and more clear. The reconfiguration and deployment of network service functions in the mode is in the cloud. For example: Deploy AC (Access Controller, access controller) in the cloud, referred to as cloud AC, the difference between deploying AC in the cloud and deploying in the traditional mode is that the AP (Access Pointer, access node) needs to connect to the AC across the Internet. The main problem to be solved is how the AP discovers the AC and establishes a connection with the AC. [0003] On a traditional Wi-Fi network, the AC usually manages the AP thro...

AI Technical Summary

Problems solved by technology

In this way, the AP needs to be expanded to allow the AP to support the corresponding private protocol, and the cloud AC cannot manage the AP that does not support the private protocol; at the same time, the process of the tunnel mode is relatively complicated, and a public http proxy (hypertext connection protocol proxy server) is required. ) and tunnel-terminated facilities or similar facilities, these problems lead to relatively high deployment and operation costs for cloud ACs using private protocols

[0004] In view of the relatively high cost of deployment and operation of cloud AC in the environment of private network IP in related technologies, no effective solution has been proposed so far
