  • Patent number: 11855708
    Abstract: Techniques and apparatus for determining quality of experience (QoE) for wireless communications are described. One technique involves transmitting a QoE support message to an access point (AP) within an access network. The QoE support message queries whether the AP supports providing key performance indicators (KPI(s)) indicative of QoE provided by the access network. An indication of whether the AP supports providing the KPI(s) is received in response to the QoE support message. The KPI(s) are received when the AP supports providing the KPI(s). A determination is made whether to communicate with the AP based at least in part on the KPI(s). Communications are then performed in accordance with the determination.

  • Publication number: 20230401072
    Abstract: A network device has a first OS component, a second OS component is added to run concurrently with the first. The first OS component transmits routing information to the second OS component where it is stored in memory. The second OS component registers with a routing infrastructure to receive packets that are routed to the first OS component. A timestamp and a first ID are added to a first instance of a packet and transmitted to the first OS component. The timestamp and a second ID are added to a second instance of the packet and transmitted to the second OS component. First functionality data for the first OS component is transmitted to a controller. Second functionality data for the second OS component is transmitted to the controller. The first and second functionality data are compared to determine whether to replace the first OS component with the second OS component.
