Embodiments described herein allow for the improvement of roaming in a multi-link and / or multi-access point (AP) environment. The needs of a wireless device or applications operating on the wireless device can dictate what types of connections are desired. These needs can be encapsulated within an objective function, which can dictate an overall roaming strategy associated with a network device or associated application. This objective function can allow for various APs to suggest, or wireless network devices to request, different target roaming AP candidates based on an implicit or explicit criteria. This criteria can be focused on maximizing throughput, or minimizing loss, or a specific combination of other needs. The objective function can be determined by the wireless network device, the AP, or a remote device such as a wireless local area network controller, or cloud-based network management service. The objective function can also be dynamically adjusted based on subsequent events.

Method for application control and Quality of Service (QoS) handling may be provided. A request may be received for scheduling a communication between an Access Point (AP) and a user device for sending data of an application. It may be determined that the request does not comprise network characteristics of the application. In response to determining that the request does not comprise the network characteristics of the application, the network characteristics may be requested from a Wireless Local Area Network (WLAN) controller. The network characteristics may be received from the WLAN controller. Schedules for the application may be determined based on the network characteristics. The schedules may be enabled.

Devices, networks, systems, methods, and processes for dynamically allocating channel widths to Access Point (AP) radios for both a data exchange operation and a ranging operation are provided herein. A wireless network may include a Wireless Local Area Network Controller (WLC) and a set of APs. A network device of the wireless network may allocate a first channel width to a plurality of radios of the set of APs for the data exchange operation. Further, the network device may determine that the set of APs is enabled for the ranging operation. Furthermore, the network device may allocate a second channel width to a set of radios of the plurality of radios for the ranging operation such that inefficiencies in channel width allocation for one or both the data exchange operation and the ranging operation are suppressed. The allocated second channel width may be different from the allocated first channel width.

Described herein are devices, systems, methods, and processes for inspecting wireless client traffic in a software-defined wide area network (SD-WAN) deployment. A controller device may generate and send capture policies to various network devices, including, but not limited to, access points (APs), wireless local area network (LAN) controllers (WLCs), and edge devices. The policies may each include a filter field and an action field, which can be dynamically updated based on current network conditions and needs. Upon receiving the capture policy, the APs can filter the wireless traffic and set an Inspect flag in the control and provisioning of wireless access points (CAPWAP) header on the matching wireless packet. The edge devices or WLCs may then inspect the wireless traffic by checking the Inspect flag in the CAPWAP header. The technique may provide a more efficient and scalable solution for inspecting wireless client traffic, with minimal impact on network performance.

An authentication server 11 authenticates the communication terminal 14 based on the IEEE802.1X standard. A wireless LAN controller 12 operates as an authenticator based on the IEEE802.1X standard, and communicates EAPOL frames with the communication terminal 14 and RADIUS packets with the authentication server 11. The authentication server 11 selects one of multiple authentication methods based on identification information APID that identifies a wireless LAN access point 13 and that is included in the RADIUS packets from the wireless LAN controller 12, and proposes use of the selected authentication method to the communication terminal 14.SELECTED DRAWING: Figure 1
