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.

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.

Systems and methods enhance handling, within an access point (AP) of a local area network, of content from a content provider. A content session core of the AP opens a session with the content provider and allows interaction between a user of a first end device and the content provider via the session. Content from the content provider is received at the content session core and forwarded for play on the first end device. The content session core may mirror the content to a second real end device without requiring an additional session with the content provider, and may switch play of the content from the first to the second end devices without disconnecting the session with the content provider. A wireless LAN controller enhances a connectivity experience of a mobile device by determining its location and predicting when to handoff connectivity between wireless APs of the LAN.
