  • Publication number: 20250039047
    Abstract: Devices and methods that incorporate sustainability data within a header of a data packet to allow for the generation of sustainable configurations for various network devices are disclosed. Power efficiency is obtained at a node-level by including metadata to existing network flows, in an in-band/in-situ configuration. This information may be used for optimum flow placement. Received data packets may be formatted with sustainability data within a metadata shim. The received data packets are processed, and a sustainable configuration is generated for the one or more network devices. The generated sustainable configuration is transmitted to the one or more network devices to enable efficient and effective management of network devices by incorporating sustainability data into the data packets.

  • Publication number: 20240365118
    Abstract: Techniques are described for providing secure audio calls between a calling party and a receiving party. Upon receiving a call request from a call initiating party, a notification is sent to the intended call recipient. The call recipient can send a request for a secure call. Upon receiving the request for a secure call, a bi-directional multifactor authentication is performed to authenticate the identity of both the call initiating party and the call receiving party. In response to successfully authenticating both parties, a secure call between the parties is established. One or more secure key tokens or other metadata can be embedded in the call to ensure security of the call.
