Description

Technical Field

[0001] This application relates to the field of WLAN networking technology, and in particular to a network control method, device and storage medium based on virtual wireless access points. Background Technology

[0002] With the development of Wi-Fi wireless network communication technology, Wi-Fi network coverage is becoming increasingly widespread. Currently, the main method for Wi-Fi-based network coverage is to use the capwap protocol to negotiate between the controller and the wireless terminal and to distribute configurations.

[0003] In existing technologies, when there is an internal network and an external network, two different AC controllers are used. One AC controller is responsible for the management and control of APs on the internal network, and the other AC controller is responsible for the management and control of APs on the external network. In addition, a virtual tunnel needs to be established between the internal network AC and the external network AC. External network traffic accessed through the internal network AP is then routed to the external network AC through the tunnel for separate management.

Detailed Implementation

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.

[0059] In existing network control methods based on virtual wireless access points, the controller and wireless terminal negotiate and distribute configurations through the capwap protocol.

[0060] In existing technologies, when there is an internal network and an external network, two different AC controllers are used. One AC controller is responsible for the management and control of APs on the internal network, and the other AC controller is responsible for the management and control of APs on the external network. In addition, a virtual tunnel needs to be established between the internal network AC and the external network AC. External network traffic accessed through the internal network AP is then routed to the external network AC through the tunnel for separate management. This requires setting up independent ACs and APs for WLAN networking, which presents technical problems of high deployment and maintenance complexity and cost.

[0061] The network control method, device, and storage medium based on virtual wireless access points provided in this application virtualize physical wireless access points based on a wireless access point hardware platform, determining a first virtual wireless access point and a second virtual wireless access point. The first virtual wireless access point is used for wireless coverage of the internal local area network (LAN), and the second virtual wireless access point is used for wireless coverage of the external wide area network (WAN). Based on the OpenFlow protocol, a virtual controller forwards the configuration parameters and flow tables corresponding to the first and second virtual wireless access points, thereby logically virtualizing the physical access point (AP) into two virtual APs. The virtual controller controls the forwarding of the configuration parameters and flow tables of the virtual APs. Computers on the internal network access the internal wireless network through the internal virtual AP (i.e., the first virtual wireless access point), and computers on the external network access the external wireless network through the external virtual AP (i.e., the second virtual wireless access point). This achieves the effect of distinguishing between internal and external networks at the traffic forwarding level, thus reducing the complexity and cost of WLAN network deployment and maintenance.

[0062] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments.

[0065] In this embodiment, the wireless terminal uses software virtualization to create two logically independent virtual APs on a general hardware platform, namely the first virtual wireless access point and the second virtual wireless access point; the first virtual wireless access point and the second virtual wireless access point are responsible for the wireless coverage of the intranet and the wireless coverage of the external network visitors, respectively.

This distinguishes between the internal and external networks at the traffic forwarding level, achieving the effect of service isolation between different networks.

The first virtual wireless access point is used for wireless coverage of the internal local area network (LAN), and the second virtual wireless access point is used for wireless coverage of the external wide area network (WAN). Based on the OpenFlow protocol, a virtual controller forwards the configuration parameters and flow tables corresponding to the first and second virtual wireless access points, thereby logically virtualizing the physical access point (AP) into two virtual APs.
