Abstract: Systems and methods are provided for master media clock recovery. In various embodiments, recovering a master media clock may comprise receiving clock reference format (CRF) packets carrying timestamps (Ts). Differences of Ts between adjacent CRF packets may be calculated, and an average difference of Ts between adjacent timestamps may be calculated. A recovered frequency of a master clock may be based on the calculated average difference of Ts between adjacent timestamps. The recovered frequency may be used to regulate a timing of, for example, a kernel module and/or a media application.

Abstract: Systems are methods are described which allow for “zero-touch” provisioning (ZTP) to be used to seamlessly bring up devices such as Gateways/Access Points/Switches or any other networking devices connected over different uplink types such as aggregated links (Static LAG, LACP), trunk ports, and the like. Provisioning is adapted specifically for trunk and/or LACP ports in order to maintain the automation and optimization benefits typically provided by ZTP. A method can include transmitting a discover message, and receiving a response message based on the discover message. Then, determining whether a pre-defined extension is included in the response message that indicates a port type and a virtual local area network (VLAN) configuration. Automatic configuration of one or more ports and a VLAN can be performed as indicated by the pre-defined extension. Thus, ZTP can be restarted in accordance with the configuration of the network device.

Abstract: An Internet-connected device, such as a car, refrigerator, or even a laptop can use a second device, such as a cell phone, to support cryptographic operations and communication with token service providers or other processing services requiring pre-provisioned capabilities that may include cryptographic secrets. By removing the need to store personally sensitive data in “Internet of Things” (IoT) devices, a user's personal information and other sensitive financial information may be contained to a relatively small number of devices. This may help prevent theft of goods or services by IoT devices that are not always under the close control of the user.
