    Abstract: Embodiments herein describe association rules (e.g., affinity and anti-affinity rules) that a wireless device can use to optimize its performance in a Wi-Fi network. While BSS coloring is typically used to eliminate color collisions, the embodiments herein use BSS coloring to define what BSS colors should be on the same channel and which should not. For example, an affinity rule can indicate that a wireless device assigned a first BSS color (e.g., red) can share the same channel with wireless devices (or BSSs) assigned a second BSS color (e.g., green). In contrast, an anti-affinity rule can indicate that a wireless device in the red BSS color cannot share a channel with a wireless device assigned to a third BSS color (e.g., blue). The embodiments herein permit the wireless devices to be grouped with, or separated from, wireless devices having different BSS colors.

    Abstract: A network function virtualization (NFV) compute element installs an image supporting a virtualized network function (VNF) on the element. The image includes instructions/data to initiate a TCP connection between the element and a Software Defined Network (SDN) controller upon reboot of the element. Upon rebooting, the element establishes, as client in accordance with the instructions/data, a TCP connection with the controller. The element then accepts, as a cryptographic network protocol server, a connection via the TCP connection from the controller as a client in accordance with the instructions. Next, the element accepts, as a network management protocol server, a connection via the cryptographic network protocol connection from the controller as network management protocol client. The element receives, from the controller over the network management protocol connection, commands regarding the status of the rebooted compute element, and then transmits, to the controller over the network management protocol connection, responses to the commands.

    Abstract: Embodiments herein describe a group of APs (115A-115D) that uses a shared radar cache (120A) to select a new channel after vacating a current channel when performing dynamic frequency selection (DFS). The group of APs (115A-115D) can set aside memory to store status information about the DFS channels in the frequency band. For example, when one AP detects a radar event (and has to vacate a DFS channel), the AP updates an entry for that channel in the shared radar cache (120A). The APs can also query the cache to determine a new channel after vacating its current channel. That is, the shared radar cache may store the most recent radar events occurring in a channel. In this manner, the APs can select a new channel that has little or no recent radar events, which reduces the likelihood the AP will have to vacate the new channel.

    Abstract: Techniques are described to provide multipath mobility via Domain Name System-as-an- Authoritative Source (DNS- AS) techniques, In one example, a method includes obtaining, by a multipath policy decision element, a plurality of multipath policy recommendations for an application, wherein the plurality of multipath policy recommendations are obtained from one or more multipath policy recommendation elements; combining the plurality of multipath policy recommendations to generate a policy enforcement decision, wherein the policy enforcement decision identifies, at least in part, one or more network paths that are to be utilized for one or more packet flows associated with the application, wherein each of the one or more network paths is associated with an access type; and enforcing the policy enforcement decision for one or more packet flows associated with the application.

    Abstract: An electronically a steerable and switchable antenna array is provided that can produce a first beam with a first coverage range and a second beam with a second coverage range by selecting one of a first and a second beamwidth for both the first and second beams; in response to selecting the first beamwidth: switching signal inputs to narrow-beam antenna arrays; steering the first beam to one of a first positive, negative, or zero offset position; independently steering the second beam to one of a second positive, negative offset, or zero offset position; and transmitting signals received from the signal inputs via the first beam and the second beam; and in response to selecting the second beamwidth: switching signal inputs to wide-beam antenna arrays; and transmitting signals received from the signal inputs via the first beam and the second beam.
