Differentiated service in a federation-based access network is provided by receiving a set of credentials from a User Equipment (UE) for a wireless network offering a plurality of service levels. In response to determining that the set of credentials indicate a realm associated with a given service level, network access is provided to the UE according to the given service level. In response to determining that the given service level is not a highest service level in the wireless network, a list of one or more preferred realms is transmitted to the UE, where each realm of the list of one or more preferred realms is associated with one or more higher service levels than the given service level.

Described herein are embodiments related to systems, methods, and processes for sharing sustainability-related attributes and data across multiple domains. More specifically, some embodiments describe a sustainability aggregation device which may include a controller or other processor, and a memory. The memory includes a sustainability aggregation logic that can receive telemetry data associated with a first network domain, and in response, generate a multi-layer topology graph for the first network domain. In response to the graph being generated, it can be augmented with one or more sustainability-related attributes. However, the device can prune the augmented multi-layer topology graph based on one or more export policies and export the pruned augmented multi-layer topology graph to a second network domain. The multi-layer topology graph may also be utilized within a closed-loop system to monitor various aspects of the network domain and adjust one or more configurations as needed based on the received data.

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.

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.

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.

Techniques for ultra-short-term resource forecasting for a network device are described. A selection of a time series algorithm from a set of time series algorithms for determining capacity right-sizing of a local resource is received, the is selection based at least in part on current local traffic conditions. Based on current local traffic conditions, parameter values to be used in the algorithm are determined, the parameters are associated with the time series algorithm selection. A number of data points for input to the time series algorithm are determined, the data points are a sequence of values representing an amount of the local resource used by the network device at a point in time and are collected at predetermined time intervals. Based on a calculation of the time series algorithm using the number of data points and parameter values, the right-size capacity of the local resource for the network device is determined and provided.

Devices, systems, methods, and processes for managing network devices through generated predictions and associated confidence levels are described herein. Networks within a floorplan can be operated at full capacity all day in an inefficient way when not adjusted due to traffic patterns and seasonality changes. Data related to the topology of the network, along with historical data can be utilized to generate predictions of various network needs. For example, the overall network throughput capacity needs may be predicted for a series of points in the future. An associated confidence level can be generated as well including one or more confidence intervals. These can be utilized to select a future need for the network and generate a corresponding sustainable network configuration for the network devices and/or their transceivers that can provide sufficient network needs while minimizing the overall power used. This can be automated over time once trust has been established.
