Abstract: Methods are provided for selectively depowering any device(s) that seem unnecessarily redundant to strike a balance between resiliency and sustainability to reduce energy costs. The analysis may include a current application mix in use on network paths. For example, a policy may require that at least two available paths are actively energized when real-time collaboration apps are running. Examples of a real-time collaboration app may be data mining in an online database stored elsewhere in the network or holding a video conference call. This double path redundancy can deliver increased application availability. And, in instances where just web/email are actively running, then a backup path that may be energized in less than a second, if a primary path loses connectivity. This lower-power method can also provide increased application availability.

Abstract: Granular guard interval tuning may be provided. A delay profile for a plurality of sub-bands in a serving channel may be created. Then delay spread information from at least one calibration helper device for the plurality of sub-bands in the serving channel may be received. Next, a delay spread matrix based on the delay profile, the delay spread information, and a location of the calibration helper devices may be created. The delay spread matrix may then be used to determine optimal Guard Intervals (GIs).

Abstract: Devices, systems, methods, and processes for network device power management at the floor level are described herein. Network devices can communicate with various devices in a wireless network. However, environmental changes, barriers, and other hazards exist in each deployment environment. To better understand each deployment environment, a floorplan can be generated by sending out a plurality of test frames. These test frames can be formatted with power data that is associated with the transmission power level that each test frame is transmitted at. The receiving network device can compare this power data with an actual measurement of the received signals. This data can all be packaged into a client report that can be sent back to the transmitting device which can then process this client report from multiple network devices such that a floorplan can be generated which can be utilized to make more efficient network decisions in the future.

Abstract: Techniques and apparatus for performing sticky client detection and/or remediation with machine learning are described. An example technique includes determining one or more parameters associated with roaming activity of a client station (STA) within a wireless network. The one or more parameters are evaluated with a machine learning model to predict a sliding boundary associated with the client STA, a first access point (AP) within the wireless network, and a second AP within the wireless network. Information associated with the sliding boundary is transmitted to the first AP. A frame including a request for the client STA to roam to the second AP and the information associated with the sliding boundary is transmitted to the client STA.

Abstract: Techniques performed by offload computing devices that establish and advertise confidential computing environments for use by other computing devices. The offload computing devices may each be executing an attestable bootloader that creates the confidential computing environments, advertises the available resources to the other computing devices, establish secure encrypted channels with the other devices, and run processes in the confidential computing environments on behalf of the other computing devices. In addition to advertising the availability of computing resources in the confidential environments, the offload computing devices may additionally advertise performance metrics associated with the confidential computing environments. Computing devices may receive the advertisements, and send requests to the offload computing devices to run processes on their behalf in the confidential computing environments.

Abstract: In one embodiment, a device registers with a controller for a mesh of overhead access points. The device receives, from the controller, a communication schedule for the device. The device generates a message to be sent to the mesh of overhead access points. The device transmits, according to the communication schedule, the message as a beam cone directed substantially upward relative to the device towards the mesh of overhead access points. The message is received and relayed by one or more particular access points in the mesh without the device previously performing a wireless association exchange with those one or more particular access points.

Abstract: Techniques for identifying nodes in a data center fabric that are affected by a failure in the fabric, and selectively sending disaggregation advertisements to the nodes affected by the failure. The techniques include a process where a component monitors the network fabric to identify communication paths between leaf nodes, and determines what leaf nodes would be affected by a failure in those communication paths. The component may detect a failure in the network and determine which communication paths, and thus which leaf nodes, are affected by the failure and send disaggregation advertisements to the affected leaf nodes. In some examples, ingress leaf nodes send data through the fabric that indicate egress nodes for the communication paths. Intermediate nodes along may receive the data from the leaf nodes to identify communication paths, and the notify only affected nodes upon detecting a failure in the network.

Abstract: In one embodiment, a controller identifies access points forming an overhead mesh of access points in an area, each access point comprising one or more directional transmitters each configured to transmit a beam cone in a substantially downward direction towards a floor of the area. The controller assigns the access points to access point groups. The controller generates communication schedules for the access points such that each access point in an access point group is on a common channel and only one of neighboring directional transmitters of access points in that group is able to transmit at any given time. The controller sends the communication schedules to the access points forming the overhead mesh of access points in the area.

Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a random IP address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a random IP address that cannot be used to identify the endpoint device or service. The client device may then communicate data packets to the server using the random IP address as the destination address, and a gateway that works in conjunction with DNS can convert the random IP address to the actual IP address of the server using NAT and forward the data packet onto the server.

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.
