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.

Abstract: Techniques are described herein for managing access to sensitive data detected within an electronic communication. In some embodiments, such techniques may comprise receiving, from a sender, an electronic communication directed toward a first recipient. The techniques may then comprise identifying one or more pieces of sensitive data within the electronic communication, providing a content of the one or more pieces of sensitive data to a data hosting device to be stored in a memory location and first information associated with the first recipient used to access the memory location, updating the electronic communication to replace the one or more pieces of sensitive data with a reference to the memory location, and transmitting the electronic communication to the first recipient.

Abstract: Devices, systems, methods, and processes for dynamically reducing the size of a video transmission are described herein. An energy-saving video transmission device can include a controller, a memory, a communication port coupled with at least a second device, and a virtual meeting logic configured to establish a virtual meeting with a video transmission. The video transmission is transmitted to at least the second device. The virtual meeting logic can determine a virtual meeting configuration and collect sustainability attributes data. Based on the collected data, an energy-saving video transmission rate can be selected. Often, this can indicate how often to capture and transmit keyframes of the video transmission instead of the entire video transmission. Finally, based on the energy-saving video transmission rate, a reduced size video transmission can be transmitted over a network. Subsequently, additional events can be detected that allow for the dynamic adjustment of the energy-saving video transmission rate.

Abstract: A network of devices can be stabilized by administering an energy-aware topology that corresponds to a desired state derived in part from one or more sustainability metrics. Devices suitable for stabilization can include a processor, a memory, a plurality of elements, a communication port coupled with one or more neighboring devices, and an energy-aware topology logic. The energy-aware topology logic can monitor incoming traffic from one or more neighboring devices, receive current state data associated with the plurality of elements, and receive update data from the one or more neighboring devices via a sustainability-related augmented IGP. Also, the energy-aware topology logic can generate a desired state for the device based on at least the received current state data and update data. One or more of the plurality of elements may be modified in response to the generated desired state, wherein the modification involves changing one or more sustainability-related capabilities.

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.

Abstract: Aspects of the disclosure include a method and associated network device. The method includes authenticating an identity of a user of a client device after the client device is associated with an access network provider. Authenticating the identity of the user comprises receiving, from an identity provider, a credential associated with the identity, and receiving, from the identity provider, information identifying a network-based service to be applied to network traffic with the client device. The method further includes establishing, using the credential and the received information, a secure connection between the access network provider and a service provider that is capable of providing the network-based service. The method further includes receiving network traffic from the service provider. Packets of the network traffic include an assurance value that enables the client device to determine that the network-based service is being provided by the service provider.

Abstract: Presented herein are techniques to facilitate infrastructure and policy orchestration in a shared workspace network environment. In one example, a method may include obtaining, by a service broker, a reservation request from a consumer network for a consumer, wherein the reservation request seeks a reservation to reserve, at least in part, at least one workspace device for the consumer for a workspace for a particular day and a particular time period; based on determining that the at least one workspace device is available, providing a response to the consumer network that includes a first indicator for identifying the reservation of the workspace and at least one second indicator identifying the at least one workspace device; and upon receiving a session request from the consumer network that includes the second indicator, establishing a management tunnel to interconnect the consumer network and the at least one workspace device via the service broker.

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.

Abstract: Systems, methods, and computer-readable media for orchestrating data center resources and user access to data. In some examples, a system can determine, at a first time, that a user will need, at a second time, access to data stored at a first location, from a second location. The system can identify a node which is capable of storing the data and accessible by a device from the second location. The system can also determine a first service parameter associated with a network connection between the device and the first location and a second service parameter associated with a network connection between the device and the node. When the second service parameter has a higher quality than the first service parameter, the system can migrate the data from the first location to the node so the device has access to the data from the second location through the node.
