Abstract: Energy-aware configurations can be utilized to operate a network based on sustainability-related metrics. In many embodiments, a suitable device includes a processor, a memory commutatively coupled to the processor, a plurality of elements, a communication port, and an energy-aware topology logic configured to collect topology data from one or more network devices, wherein each of the one or more network devices include a plurality of elements. The energy-aware topology logic can receive power source data and power usage data related to plurality of elements and generate an element energy coefficient (EEC) for a plurality of elements. Subsequently, the energy-aware topology logic can also generate an energy-aware configuration for at least one of the one or more network devices, and then pass the generated energy-aware configuration to the at least one network device, wherein the energy-aware configuration is configured to steer traffic based on at least one sustainability-related metric.

Abstract: A network infrastructure component determines a risk measurement associated with a wireless client device's use of a device address, and provides an advisory with respect to an address rotation strategy of the wireless client device based on the risk measurement. In some embodiments, the risk measurement is based on one or more of an exposure, by the wireless client device, of information on the wireless network that identifies the wireless client device and/or a characterization of a security of the wireless network environment in which the wireless client device operates.

Abstract: Techniques are described for quickly rerouting traffic to an application hosted on a first Virtual Private Cloud (VPC) location. In the event of an error in routing traffic to the first VPC portion traffic can be rerouted to a second VPC portion. The first and second VPC portions can be different portions of the same VPC or could be different VPSs. The techniques include steps for calculating a predetermined route to the second private virtual cloud location. The techniques further include steps for monitoring data for detecting an error in the first cloud location. The steps further include detecting a potential error based on the monitored data, and also verifying that the potential error is in fact a valid error. In response to verifying that the error is a valid error, further steps include performing a fast reroute of traffic to the second cloud locations along the predetermined route.

Abstract: An authorization device obtains a registration request associated with an end device, the registration request including a new randomized media access control (MAC) address associated with the end device; determines whether the end device is authorized to use the new randomized MAC address; transmits a message to the end device with a first randomly generated number when it is determined that the end device is authorized to use the new randomized MAC address; obtains integrity information associated with the end device, the first integrity information being computed based on the first randomly generated number; transmits a request to a validation system to validate the end device based on the first integrity information; obtains an indication that the end device is validated; determines policies associated with the end device when it is determined that the end device is validated; and applies the policies to the end device.

Abstract: Devices, systems, methods, and processes for conducting sustainability-aware virtual meetings are described herein. When establishing virtual meetings, each of the participants can have various devices, locations, histories, and other data associated with them. This data can be packaged together as a user profile which can be transmitted to a virtual meeting service or a host that can receive the various user profiles and generate a meeting profile that can be utilized to maximize the overall sustainability of the virtual meeting. The meeting profile can include configuration suggestions that can be transmitted out to each corresponding device of the participants to either prompt or automatically adjust one or more settings, features, or other configuration, such as energy-saving features, that can increase the overall sustainability. These conditions can be monitored during the meeting and adjusted dynamically in response to changing conditions. In response, devices can adjust configurations or alter audio/video transmissions.

Abstract: Network energy efficiency and green power selection may be optimized by employing graph-oriented service chains configured to share sustainability attributes and metadata augmentation. More specifically, network Service Function Chain (SFC) creation can include a set of power and energy-specific and sustainable attributes. In general, the goal of SFC is to enable the creation of a service path that matches the specific needs of an application or service. SFCs are composed of a sequence of network functions, such as firewalls, load balancers, intrusion detection systems, and other services. Each network function performs a specific task on the network traffic, and the packets are passed from one function to the next until they reach their destination. Overall, SFCs are a powerful tool for managing complex network environments, enabling network administrators to deploy and manage network services more efficiently and effectively.

Abstract: In one embodiment, an access policy enforcement service receives a user authentication request from an end-user device. The access policy enforcement service identifies a telemetry collection intent from the user authentication request. The access policy enforcement service determines a monitoring policy based on the telemetry collection intent identified from the user authentication request. The access policy enforcement service configures, according to the monitoring policy, one or more telemetry collection agents to collect telemetry for traffic associated with the end-user device.

Abstract: A method of orchestrating one or more radio resources among various services executing within a container. The method includes obtaining, by an orchestration engine executing on a network device, a request, from a first service of a plurality of services, for use of a physical/hardware resource that connects a container running on the network device to a network. The request from the first service has a particular priority. The plurality of services execute within the container. The method further includes determining whether to connect the first service to the network via the physical/hardware resource based on the priority and an availability status of the physical/hardware resource and establishing, at a kernel level, a connection between the first service and the physical/hardware resource based on the determining.

Abstract: Presented herein are techniques to shield transmissions from being received and the information contained in them recovered by unwanted devices. Multi-user multiple-input multiple-output (MU-MIMO) techniques are employed, and in particular the spatial dimension aspects of those techniques. Shield nodes are controlled to transmit in a way to obscure the downlink streams transmitted by a wireless access point that are intended for a particular client device to anything outside of the shielded area, and also to obscure uplink streams from one or more client devices to the wireless access point to anything outside of the shielded area but allowing the uplink streams to be well received by the wireless access point.
