Typical Fit AP Networking

Figure 4-1 shows the Fit AP networking. In this networking, an AC must be deployed to work with Fit APs to implement functions such as STA access, AP onboarding, authentication, routing, AP management, security, and QoS.

Typical Fat AP Networking

Figure 4-2 shows the Fat AP networking. Fat APs can independently implement functions such as STA access, authentication, data security, service forwarding, and QoS.

Figure 4-2 Typical Fat AP networking

Some APs in Fat mode also support the leader AP networking (depending on the specifications) and can manage a small number of Fit APs, thereby implementing small-scale batch deployment and simple O&M of basic WLAN services.

Typical Cloud AP Networking

In this networking, APs work in cloud mode and managed by an SDN controller on the cloud. They together implement functions such as STA access, AP onboarding, authentication, routing, AP management, security, and QoS. An enterprise can choose to use the Portal authentication server integrated on the SDN controller or the authentication server deployed by itself. Figure 4-4 shows the typical cloud AP networking.
