Abstract: 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.

Abstract: Devices, systems, methods, and processes for orchestrating and managing various lower-power modes in a variety of network devices within a network are described herein. Various network devices, such as access points may be capable of entering one or more lower-power modes of operation that utilize less electricity to operate. When initiating a lower-power mode, the various clients that the network device has been handling need to be handed off to a sibling AP nearby. However, when exiting these lower-power modes, these devices may need different amounts of time to reboot and/or resume normal operations. Thus, when deciding which clients to re-associate with the waking up network device, various considerations need to be weighed based on client needs and network device capabilities. Thus, a smart environmental controller (SEC) is utilized to coordinate these processes. The SEC can be a specialized device, or a logic distributed remotely or among the network devices.

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: Devices, systems, methods, and processes for sustainably reallocating resources based on within a plurality of computing nodes of a network, such as a managed network are described herein. Each computing node may be configured to transmit infrastructure data to an infrastructure monitor or ecosystem management tool. Additional sustainability data may also be accessed either internally or externally. The infrastructure data and sustainability data may be utilized to generate one or more scores that can be evaluated against each other. These scores may be configured to reflect various conditions or facts about the computing nodes including the overall sustainability. In order to increase sustainability levels, a variety of different resource configurations can be generated and evaluated against each other and the current configuration. When a more sustainable configuration is located, it may be applied by moving resources from originating computing nodes to destination computing nodes to achieve increased sustainability goals.

Abstract: Various methods, systems, and/or processes are described herein that can operate on a minimally energized power level to detect motion and paths of motion within an environment. A device suitable for carrying out these operations may include an energization optimization logic which can be responsible for selecting a floorplan, identifying access points associated with the floorplan, determining identities, such as persons, located within the floorplan, and tracking their motion. Once this information is gathered, the logic determines a reduced power configuration and passes it to various access points in the floorplan area to reduce the energy consumption based on the configuration. This allows for energy optimization while still maintaining the tracked motion of the identities within the floorplan. The logic allows for efficient power usage in areas with high traffic flow, while still maintaining the quality of service for the identities within the space, which can change dynamically over time.

Abstract: Described herein are devices, systems, methods, and processes for managing power congestion in multi-path routing systems. Indications may be similar to the ECN, and may be used in network headers, including headers for IPv6, SRv6, NSH, or other tunneling protocols. The indications, namely EOPN, PTE, and ECMP-exclude, can provide a mechanism for managing network power consumption and controlling ECMP routing based on flow priority and characteristics. The power budget can be dynamically adjusted based on the current power source mix, which may help to achieve sustainability goals. Hashing optimizations and signaling can be utilized to manage network power congestion and bandwidth-normalized power efficiency availability. A process may be implemented to ensure there is sufficient capacity to serve the expected traffic for different next-hop paths. Additionally, the ECN can be used to quickly react to congestion, bring capacity back online, and maintain optimal network performance, even in the absence of congestion.
